I have a LS997 that I purchased from eBay a few years ago. I kept the phone at 7.0 and I definitely was able to set the APN. I used it on T-Mobile for test, I was able to enter fast.t-mobile.com as APN and everything works. I then used it on Tello (Sprint network).
I was told that I can switch to GSM, since it is T-Mobile's network, I thought no problems. Ordered the GSM SIM, activated. After I swapped the SIM, I realized that the APN cannot be set. There is simply no "..." menu like I use to. All I see is a greyed out word of "otasn" in the APN list.
I tried putting in a T-Mobile SIM. It works. I see a grayed out fast.t-mobile.com APN with a unselected radio button. But internet works and everything.
STILL NO "..." MENU.
It seems my ability to edit APN has somehow been taken away. I doubled checked the Android version is still 7.0 ZVC and I have not upgraded it.
I honestly don't know how the V20 ended up like this. Can someone help me out?
Tried installing an app that edits APN. It managed to bring up an APN setup menu. I can see the familier setup page but everything is grayed out and cannot be edited.

Try to go to options, then system updates, then select uicc unlock. Usually unlocks sim for apn if able.

That doesn't seem to do anything. I also found a post mentioning installing Pulse SMS app allows changing APN. That didn't work either. I am really puzzled why the ability to change APN were gone. I am certain that I was able to add APNs. At least right now, it can detect T-Mobile SIM and use its APN automatically (likely because I entered it in the past). I am worried that once I factory reset the phone, even that is gone.

There is a small app that can add an additional APN entry that might work here as some people have done this on the Sprint LG G8. Have a look at this set of comments for the link of the app.
But you should also be aware that some time next year, your LS997 will stop working for phone calls since it can't get VoLTE on T-Mobile, so once they take down both 2G and 3G networks, it will become a data-only device in the U.S.

I read that if you go to TMobile and get a new sim that we can still have service. Just be fully TMobile. No Sprint at all. Something to do with new network merge tool they have. Its called TNX.

I was already referring to full T-Mobile here. The LS997 isn't configured to get VoLTE at all, so all calls would still just go through 2G/3G on any network. It's easy to check by having cellular data on with Wi-Fi off and making a call and see if the LTE icon stays on or immediately switches to 3G or below.
For the few of us on rootable LS997 models, there might be a wild experiment to try by running US996 firmware and see if VoLTE can get enabled on there.

I found a board for a rootable ls997, but I currently have just root shell sadly. Oreo here. Old full root died. I may be screwed. We shall see in a few months. Unless tmobile version will work fine still. I may be forced to downgrade (upgrade). I dont have tmobile version, but if I were to get another v20 maybe only option aside from an us996. I hate this forced crap. V20 days maybe closing up. Super sad n stuff.

You're not too far off-topic since the future of the LS997 on T-Mobile still concerns OP here. My MVNO already stopped new Sprint network activations and started moving to Verizon, so I jumped over to T-Mobile prepaid and finally let go of my LS997 as my daily driver. I could still mess around later this year with US996 firmware and let you know what I can find.
But if you want to stick with your unrootable LS997, then you still have plenty of time for next year. From what I read, T-Mobile will shut down their 3G network by July 1st, 2022 while no official date has been set for turning off their 2G portion. However, even with 2G and 3G still working for calls, if you ever happen to be in a spot where there's only an LTE band signal without 2G/3G, then you won't be able to make or take calls there.
So the only safe way to keep going on a V20 with T-Mobile is to get their H918 model. But even then, you're still limited to Android Oreo, which some apps may eventually abandon as they might raise the minimum requirement to Pie or higher at some point.

If your LS997 is SIM-unlocked like OP's, then you could get a T-Mobile SIM card and keep going until T-Mobile shuts down both their 2G & 3G networks next year. Just be aware that no Sprint-branded phone will pass T-Mobile's IMEI checker. But you should have a VoLTE-compatible backup phone ready to go if you start running into LTE-only or low-signal areas.
FWIW, I factory reset my LS997 V20 (still on Android 7.0) and I still cannot edit the APN. Even worse is that I now cannot use it with T-Mobile since the fast.t-mobile.com APN is gone. I regret resetting it. It is now useless as a smartphone since Sprint CDMA is history and phone cannot pick up LTE signal from other LTE carriers.
I have no idea why my LS997 lost its ability to edit APN even though I did not accept software updates. There does not seem to have any way to bypass the APN write protection.

To me it sounds like sim relocked. Might need to call tmobile/Sprint to unlock again. You could also try rooting (since you have rootable firmware [under zvd]) or temp root; then use an app called shortcut master lite and edit apn that way. I am not sure if app works without root access. I really don't know otherwise. Dumb when crap auto happens. If your sim is unlocked again. You may not need apk to edit apn again.
I guess V20 has a different way of locking the SIM. The modem seems to be SIM unlocked but the phone's firmware prevents me from editing or adding APN. And they seem to be good at it as I have tried multiple methods to no avail.
In addition, I don't know how T-Mobile/Sprint could unlock the phone since phone does not ask for unlock pin.
Maybe rooting would work, if my firmware can still be rooted. I might as well just throw in a new OS since updating firmware will relock the APN. I
As far as I know, only software versions up to ZV7 (security patch level date of May 1, 2017) can get full root. On those versions, you could freely edit the APN values within a hidden menu, and those options seem to be gone on later software.
Sprint phones are notorious for having grayed out APN settings out of the box or after factory resets or major Android version updates. When they're grayed out, you pretty much have to hope that whatever default APN values the phone reads from your SIM card are the ones you want. Otherwise, you'll have to find another way to edit the values. The small app I linked earlier from the G8 is an interesting approach, but it appears to require ejecting the SIM card with the phone staying on which is not possible on the V20 since the battery blocks the card slot, so I'm not sure if that method can be applied to the V20.
I think Sprint and T-Mobile do SIM-unlocking by connecting to a remote server.
This is actually the 2nd LG LS997 I bought off eBay. I think both phone comes with ZV7 or so. The first phone I tested that it is unlocked and I let it upgrade 1 after another until it reached Android 8 and I lost data. Since the seller advertised the phone as unlocked, I didn't have issue returning the phone.
The 2nd phone I am more careful and I stayed at ZVC. I verified that I can edit APN and all even after factory reset. I think the reference about ZV8 is that user cannot edit APN using the Hidden Menu trick beginning ZV8. But supposingly, my phone is unlocked so APN can be edited. But throughout the internet, there are LS997 users reporting phone is locked again after upgrading to Android 8.
On top of that, I am not sure how my phone was unlocked as I also discovered that if I enable secure boot (require PIN during boot) will disable APN editing. I have no idea why they are related. My guess is that my phone isn't unlocked via official means and maybe someone messed with the bootloader in order to unlock.
I am rethinking my options:
1. Root my phone (since I am still on Android 7) and try APN editing using root privilege (not sure what app to use)
2. Root my phone and install LineageOS. Since it is a different firmware, I assume there won't be APN write protection.
3. Upgrade phone to Android 8 and try calling T-Mobile to unlock (I was never a Sprint customer).
4. Try eBay seller who can remote unlock phone for ~$7. They claim they can unlock LS997 with Android 8. It is a lot of hassle as I won't use my regular computer for this type of activity.
Option 1/2 and 3/4 are mutually exclusive.

My bad, I thought zvc was the root able for some reason. ZV7 yes. Its been awhile and lil under the weather. Brain is scrambled lol.
So... you mean my ZVC is not rootable?

Zvc has arb I believe. Damn Sprint. Only other way for Root possiblity would be temp root. Not full root, but you would at least have root shell. https://forum.xda-developers.com/t/3-18-71-perf-root-root-shell-for-lg-v20-variants.3990145/page-5. Download on page 5 at top post.

Hey guys, I just saw a YouTube video that was posted yesterday where the guy shows that after the update he no longer could connect with his Verizon SIM card in the axon 7. Has anybody else run into this? Mine won't be here until Monday but if this is true I'm going to be sorely disappointed. Thanks for your input.
I am on verizon with no additional problems after the update. I am still always roaming, and my signal is the same (more bars but still the same reception). LTE, MMS, SMS, Cdma all work the same.
I'm really glad to hear that. I'm not so sure the guy knew what he was doing either... Lol :silly:

Quick question for you bud. I currently have the Moto Z-Force, but I want an unlocked phone that I can root and mess around with and unfortunately this phone doesn't have that capability. Would you say this is a great alternative in terms of functionality and specs? Tia

My VZW situation. Just an FYI post AND how to fix it.
I'm on Verizon, have had my Axon 7 for over a month now. No issues other than not having VoLTE, and the occasional software farts (Using Nova Launcher now). When I initially set-up my phone, I imported all previous apps directly from the Play Store. I should have known not to install the VZW apps that were previously installed on my HTC One M8 (purchased directly from VZW), but in my excitement for the new phone, it skipped my mind. Anyhow, no issues through 9/19. "Verizon" displayed as my carrier, and full access to the LTE network.
Fast forward to 9/20 (post B27 update) when one of the VZW updated automatically (I don't recall which of the 2 apps I had installed), and BAMM, "123456" displayed as my carrier and no more access to the LTE network (3G only). Later that evening, my VZW account showed my number with an "unauthorized, non-VZW device", whereas, before the VZW app update it showed my HTC one M8. I removed the SIM and shut down the phone, re-installed the SIM and re-booted....nada. Tried what seemed to be every permutation of replacing the SIM card, played around with APN settings...no dice.
My feeling is they booted me off 4G LTE once the app recognized I was using an unauthorized, non-VZW device. The steps below solved the issue (Provided by "vzwcdma" via the ZTE Community Forum).
"As for losing LTE connectivity, I've had a similar problem before, both on the A7 and other devices. On other devices, like Motorola devices, I could just boot into the bootloader and clear the modem state partitions via fastboot, but ZTE seems to have disabled that function in the A7's bootloader. So, for the A7, I had to mess around a bit with the modem mode. Download "Network" or "4G LTE Switch" from the Play Store. Open it and scroll down to "Set preferred network type", where it should say "LTE/GSM/CDMA auto (PRL)". There isn't really a set guide for what you have to do, but try switching into LTE-only mode, try hitting "Turn off radio" and "Turn on radio" (not Airplane Mode), maybe try "LTE/CDMA audo (PRL)", maybe turn off radio, switch to LTE-only mode, turn on radio, etc. At some point (I'm not sure what) the phone will reset its modem state, and should re-connect to Verizon LTE (and when it does, switch the network type back to LTE/GSM/CDMA auto PRL.
My Verizon account also shows "unauthorized, non-VZW device". Shouldn't affect anything. I've been using an unauthorized/non-VZW device prior to the A7 with no issues as well."

Good to know! I've had so many phones and this hardware looks so awesome for the price, but of course vzw isn't gonna play nice with it without some work. Looking forward to getting mine
Verizon still working fine for me.
After the b27 update I saw improved signal strength. I'm on page plus mvno. After driving in a fringe reception area, I lost lte,and I showed as roaming. It seemed to be using boost Mobile from what the phones network menus displayed. Axon doesn't have a mobile network setting for 'system b', only auto & home only. Tried both, rebooting each time, no fix. I ended up resetting phone, fixed it all. I then switched mobile network to home only, and hoping that it's done.
PS-after b27 I had to re-enable a couple settings, pinch for screen shot, etc.
Edit: it's now been several weeks with it set to home network only. I daily drive in fringe reception areas and have better signal strength than ever, with any phone/carrier combo. All is great, no more issues. Great phone!
For reference, I'm on page plus mvno, dropped in my activated sim from my old phone into the right-side sim slot for CDMA services. Then set to home only. Done.

Just wanted to see if anyone else had inputs of post update Verizon service, good and bad... hasn't been a ton of chatter in the last week. I have a phone on its way from the egg, trying to decide if it's worth starting a new sim card with Verizon and dealing with that work around... is getting the number off a display and ordering online still the easiest way to get activated?
Works great on VZW still. Love the phone.

I'd say that the Axon works just as well on Verizon as it did prior to the update, but with potentially better signal strength though I didn't really have a big issue with that prior to the update so I'm not sure (the T-Mobile SIM does seem to do a lot better post-update...but Verizon has always worked well).
I really doubt you'll have any substantive trouble with VZW on this device, especially if you're willing and able to mess a bit with some of the more advanced settings just in case a problem does arise. Here are the oddities, and I'm trying to list *all* of them!
1. No VoLTE or (I presume) HD calling
2. Voicemail appears to have to be accessed by dialing *86 as opposed to long-pressing the '1' key
3. Roaming icon is present intermittently
4. Data roaming *must* be enabled to ensure consistent and reliable data service
5. Verizon's website won't recognize the device at all in the Account Overview pages (mine still shows the last "approved" device I had with my VZW SIM - an iPhone 6S)
6. MMS *may* require a hack to get the proper APN, though I've had no trouble with this (I'm prepaid though); the hack requires a GSM SIM, so beware of this
7. 1X reception *seems* a tad weak in terms of dBm but functionally it almost seems better than my other Verizon phones (weird!)
8. Carrier label will be either '123456,' '002127' (EvDO only), or (I think?) '31000' when not using LTE (i.e., 1X or 3G). When on LTE the phone should show "Verizon Wireless" as normal
9. A SIM/modem reset may be necessary once in a great while it seems...so it's good to understand how to navigate to the "Phone Information" screen to toggle radio settings...also, I've found just SIM-cycling with a GSM SIM will often fix any connectivity problems as well...and sometimes just rebooting the phone with no SIM at all can help too (or a combo of all the above!)
If you can tolerate the above issues then the phone is great. I really enjoy it. I've found the Verizon side of things to be pretty reliable on the Axon 7, even with my endless tinkering with radio modes and other stuff, which has seemed to get me into (recoverable) trouble a few times.
Most importantly - the endless chatter on various forums that Verizon "blocks" the Axon 7 and other non-approved devices is total bunk. In every case where I've run into an issue it can be resolved on my side - Verizon is doing nothing whatsoever to inhibit the use of the Axon 7 on its network as far as I can tell (notwithstanding activation hurdles, admittedly)...many of the people making such claims seem to be speaking from a standpoint of total ignorance and it's kind of getting annoying, to be honest...it seems like the minute someone has an issue with the Axon 7, some ignoramus gets on the relevant forums/comments and claims that Verizon is "blocking" the device. Total BS IMO.
Good luck! As far as activation is concerned...I'd say it might be best to just go to Wal-Mart and buy a cheap prepaid phone or something (looks like the HTC Desire 526 has a nano-SIM and is only $37.49 on their website)...or maybe a cheap nano-SIM'd Verizon phone off of Swappa or eBay? That's probably what I'd do...But I know neither of those solutions are particularly helpful...VZW definitely makes it a bit of a pain.

#6 might not need the GSM SIM workaround anymore after the B27 update. The + sign shows up for me all the time now, even if I only have a Verizon SIM inserted.
thanks for the list guys, i think i'll give it a shot. i'm going to try to add it as a second line to my wifes plan online. is borrowing a friends imei from a nano phone still the best way to get a new activated sim for this phone?
that 526 is a predaid, will verizon just switch that sim to plan if i call in? or are they different?

found this, not sure if this is still the rule...
http://www.prepaidphonenews.com/2016/02/new-policy-may-require-verizon-prepaid.html
"It turns out that Verizon made a policy change effective 1/17/16 that requires Verizon Prepaid Phones to be activated on Verizon Prepaid and have at least $30 in airtime applied to them before they cam be used on Verizon postpaid. A Reddit user posted a copy of an internal Verizon document detailing the new rule:
Effective 1/17/2016, customers who purchase a Prepaid 4G device must activate on a $30, $45, or $60 Prepaid plan and make at least 1 monthly service payment before they are eligible to move the device to a new or active Postpay account .
Device remains locked until first month’s payment is made on their Prepaid plan.
Device is unlocked automatically upon successful first month’s payment and can be used on Postpaid plan (new SIM or SIM swap).
Attempting to use an active Postpay SIM Card with a new 4G LTE Prepaid PIB smartphone prior to making the required monthly payment, hotlines the Postpay MDN (SFO 83643) . The hotline remains until first month’s payment is made.
Customers who activate on the $45 or $60 Prepaid plans and enroll in Auto Pay, receive bonus 1GB data per month.
If account is hotlined:
Data access, outgoing calls, and text messaging do not work.
Text message is sent to smartphone.
*VZW FREE MSG: Phone must be activated on Verizon Wireless Prepaid service and first monthly payment must be made before it can be used with any other service. *
Auto-remark is placed on the customer's account.
*SIM Swap attempted: MDN Hotlined. Phone must be activated on VZW Prepaid service and first month paid before it can be activated as postpaid. *"

Dang...yeah I think you're right about this. My mistake...ugh I wish they'd just make it easy! In that case I'd say Swappa would be the best route...I've bought a few phones off of there and it's always been a great experience.
What are your APN settings? I'm having issues getting my data to work on Verizon.

So frustrating. Before update used today Verizon in upper left corner. Switched to 123456 after update. Rebooted and it went back. After another reboot it only says 123456 and nothing I do will change it back. And now when I get an MMS hangouts tells me it needs to download it but nothing happens. I never get LTE anymore either.
Edit: not sure what I did but it's back now. Might have something to do with bearer in apn settings being lte.

That's #9 in the above list that was posted. Need to cycle the modem state of the device.
so, can someone help me with a little clarification? did ZTE ever actually disable anything regarding Verizon on this phone? i know when people quote the webinar, it sounded like they were going to. i understand that the functionality is basically all still working, but i'm wondering if maybe i'm confused on the terminology.
in this post on reddit, i heard the same thing that has been repeated by some, and i am wondering if i have my band terminology confused. is the cdma part different from the 4g lte part(and that's why it's still working)?, or is sarah just incorrect?

Axon 7
Doesn't work on Verizon yet. It supposedly has CDMA radios but the radio firmware has them disabled. ZTE can't by law enable the CDMA radios because they didn't get FCC approval for the CDMA radios. They would have to pay for the testing and then resubmit the device to the FCC to get approval before they turned on the CDMA radios through a software update.
And the device doesn't have the firmware for VoLTE, HD calling or WiFi calling on Verizon.

Just wanted to post this for anyone else that wanted to use their S7 Active with another provider and didn't want to stay with At&t
or wanted to use other sims when traveling.
( I have nothing against At&T, but there was a better option I wanted to use...ie unlimited 4g)
I wanted the S7 active but also wanted to switch from at&t (for me it was too pricey and again there was no unlimited 4g) so I thought I might be in a bind on options and was holding off on making the switch
(For me the bttery lfe alone made the S7 and S7edge completely inferior to the active and that at first was enticing enough for to me to stay with At&t)
However... I didn't realize how easy At&T themselves made it to switch.
I can confirm the S7 active (SM-G891A) running 7.0 nougat works perfectly on the other network. Not trying to give that network free marketing... but its the other carrier on a GSM network in the US.
Though its pretty straight forward.. I thought I would just state below
Prerequisites
Own your phone outright
Not on contract (or you'll presumably pay a fee)
You are the account owner
Go to this site
https://www.att.com/deviceunlock/#/
Type in your devise IMEI number and info and account email
Request unlock code
Go to your email click the confirmation (Showed up for me in about a minute)
Wait about 10-40 minutes for a second email (It says up to 48 hours but I just did this on three separate devises and they all took less than an hour)
Write down the Code provided
Turn off phone
Remove AT&T sim card and insert other carriers SIM (can be a friends, classmates, coworkers if you don't have one yet)
Turn phone on
(Pop Up generates for unlock code request)
Enter Unlock code
Done!
S7 Active free to go.
Added note:
Once your new carriers SIm comes in and If you want to keep the old number DO NOT CANCEL your line with AT&T, first insert the new SIm from the New carrier and then port your number over...
You'll keep your AT&T number that you had and automatically end your service with them. No fees no hassle as long as you met the prerequisites above.
Hope that Helps for anyone wanting to make the switch
Forgot to add, though it might be obvious I still don't want anyone to get hung up on it... you will have to set your new APN (access point names) per your new provider and or new location. It may auto populate with your new Sim card... BUT it also may be a generic APN with the new provider and not nessicarily the best 4g network.
Just Google or call your new provider and they will provide which APN is best for your S7 active on your network.
*#*#4636#*#* - To change network settings
If you are struggling with default AT&T settings:
Dial *#*#4636#*#* -> 'Device Information' -> 'Set Preferred Network Type:' -> Select 'WCDMA' or 'Global auto (PRL)'
I used to get 1 bar on LTE, now I'm getting full coverage on UMTS. I'm on MINT SIM (they are T-mobile MVNO).
I want to add, after the first week I realized 7.0 had some intermittent 4g issues (some it would say no Internet ever with full bars)
I flashed back to 6.0.1 and all the issues are gone.
Please just keep this in mind if you have issues with s7 active 7.0 off of at&t.
@Acinko thanks for the heads up on 7.0 issues. How were you able to get 7.0 on an unlocked S7 active? It keeps telling me that the firmware is up to date. (Using T-mobile service)

On t-mobile you probably want to stay on 6.0.1 and not move to 7.0 n... t-mobile is having some data issues when the phone is on 7.0
However if you want to try it anyways... download the full firm file for 7.0 and 6.0.1 (both available on this site, just search recent posts) make sure you get both so you can switch back if need e d.
And your gonna need to flash them with Odin when your phone is in download mode.
There is walkthroughs for this on this site and others so I won't repeat it all here but that is what you will need to do.
No root needed.
Here's the 6.0.1 file, you can down load from these links and use the password to open (which is in the third post)
https://forum.xda-developers.com/s7-active/development/how-downgrade-7-0-to-6-0-1-t3590649
And here's 7.0 n
https://forum.xda-developers.com/s7-active/how-to/g891a-android-n-offical-odin-package-t3581042
Just FYI due to heavy bandwidth usage with these types of files the links regularly break (or really just get taken off) so you may have to search for another upload if these stop working.
Good luck.

This is not "S7 Active" specific issue. It is overall S7 issue on Android 7.0. You don't need to downgrade to 6.0.1. Just delete all the APNs (make it EMPTY!) -> Restart phone -> Add APN -> Restart. Problem solved.
Any particular reason why you would go to T-Mo over ATT? I think ATT's network is better? If its cost than maybe consider Cricket?

I'm not sure about yours, but for sure there was issues with my active on 7.0 off of ATT and wiping / replacing APNS did not fix it. What you said to do was the first step I tried.
Then I moved on to clearing location through the other company and fully resetting networks.
Tired default APNs, tried suggested APNs tried manual and custom APNs all of which still lead to intermittent or no connectivity
It became to have regular intermittent complete loss of network and data, no matter what apn was on there.
Flashing to 6.0.1 fixed it and I never had the issue again. Again maybe it worked differently for others, but that for sure is what fixed my issues.

CFoote, I shot you over a pm.
So, I got a S7 active off swappa and it works with my cricket account. However everytime I make or receive a call a small notice a the bottom of the screen says PROVISIONAL FWD ACTIVE comes on. (see screen grabs). Basically if I am on the phone or have the phone down on a table and miss a call. My callers are being sent to this 916 area code in Sacramento which appears to be a general ATT (or old owner?) vmail bank. I have tried and failed to update from ATT instructions (failed to read data). And the 3 ATT reps I am talking to say I have to have the ORIGINAL OWNER turn the function off first! Any helpo or suggestions? Apologies if this really needs its own thread. https://goo.gl/photos/f7UzoQsQfS9sE2Vk9
Reverted to 6.0.1 and still having connectivity issues

I think I've tried all the things listed in this thread. I have a SM-G981a (unlocked) device. When I got it (on Nougat), I cleared all APNs and added the one recommended by my provider (mintsim). I had service for about one hour and then lost it and it never came back.
I rolled back to 6.0.1 and cleared the APNs and used the same mintsim recommended APN and still don't have service.
Any ideas of next things to try?
Thanks in advance.

2. text messaging and emails worked for about one day then quit
3. samsung pay has a message ..access to samsung pay has been denied call customer service
4. s health unable to open app. your device had been compromised
any ideas?
thanks
Would this work for switching s7 to Verizon?
Would this work for Verizon or because it's cdma not gsm it won't work
So just wanted to let you guys know at least this worked on my end. If you have the SM-G950U preordered S8 and using Sprint, you can edit MSL settings.
1. Go to diaper and type in ##3282#
2. Either view DATA or Edit
3. Type in '000000' as your MSL Code.
Don't know if you can really change too much but I'm going to play around a little.
Let me know if this is helpful to anyone or if anybody has any further suggestions or comments.
Worked for me also. Thanks for the information.

I got it still can't edit the APNS
Yeah not sure why we can't. However, interestingly if we try to access APN list via settings - connections- mobile networks - access point names, I can see a list of 7 APNs. I assume most are only used for OTA updates and if you set your connection. From cdma/LTE mode to global mode. If I then go into DATA Menu and edit mode and click on the APNs then I can only see 2 options (EHRPD or LTE) but I am able to select the one I want and change it. However, I do see that I don't have the option to add a APN. This might be a limitation when using Sprint as the carrier.

Well the thing is that I have a sprint Galaxy S8 with i bought "unlocked" to my surprise it wasn't I have ATT. So im looking to whatever i can t get this cellphone unlocked!!!! Since I don't have a Sprint SIM. I can't edit APNS on settings!!
Hmm well I figured you probably already tried this but earlier if I went to Settings- connections - mobile networks- network mode and changed to gsm/umts I was able to then click manual and search for network and connect to either AT&T or T-Mobile. Not sure if this Must be done first.

I went to Settings-conection- I don't have mobile networks here.
I don't know if you need to have a sprint sim for this. But right now I don't have any sim because Im using ATT and using a older phone to be able to have a phone!!!
Okay so I just tried this option. Go into the connection and network mode and change to automatic. Then had to restart. Once restarted I went back to network mode and changed to gsm. Then I went to network operators and searched for network. Got the error that it must kill data connection before searching. I selected ok and searched. Att and T-Mobile came up. I selected Att and it said it registered on AT&T. I don't have an AT&T SIM so I can't test. However, in the morning of I see my roommate I might be able to try his SIM.
Also you might have to select gsm mode and then do the ##3282# and edit mode first and then go into settings to change network operators. Not sure but it seems ##3282# edit mode must be done to unlock additional settings in the phone.

Don't have conection mode either. I'm thinking you have this enabled because you have a sprint sim in it!!
Did you buy the phone already activated on Sprint network? And also it is a G950U correct? The only reason I ask is because I think the G950U is unlocked but if it was already activated on Sprint, then you might have to factory reset the phone and have the AT&T SIM inserted to have AT&T be your carrier.

I don't know I bought it from somebody locally who said it was unlocked and yes it says G90U but when I insert the sim card it says invalid sim card.
Let me try the reset with the AT&T sim in it to see
When I first turned the phone on it never had the Sprint splash screen until it finished setting up and power cycled. That was the first thing I noticed. Also the phone should be unlocked by default bc this variant is exactly the same for the 4 major carriers. When I checked the firmware both CSC and AP it was the exact same as T-Mobile firmware.
Please let me know if that works. It is just a suggestion and there is so much confusion on this at least from my part. Not to mention not much info on the forum yet. If this works then it might shed some light on the G950U variant.

Does not work. Is says please provide the UICC that came with the phone. So apparently when you activate it with a provider it locks!!
Sounds like it might SIM carrier lock. I think the law last year stated that we have to be able to swap phone on any carrier in the US. There is a UICC unlock under settings and software updates but it wouldn't work for me. If I remember properly I had to wait about a month or two before they would let me UICC unlock it. On samfirmware there isn't an AT&T firmware uploaded yet. There should be soon. You could try to wipe and use the T-Mobile firmware as this is GSM and will at least be the network of roam for AT&T. Might at least allow you to use the SIM or at least activate on AT&T

Could do it. I wiped the Verizon one but still the sprint splash screen come on so I don't know
I posted this ? on reddit as well; however, this device is on its last legs so there's not much interest for it. I've gotten some good answers here and there on this website, but a dedicated thread to gather all the good info might be more helpful.
I still use my AT&T H910 as I don't really do much gaming on it. Calling, texting, and YouTube is what I mostly utilize it for. I just heard about the whole VoLTE requirement on specific devices after 2022 for AT&T, and 2021 for T-Mobile.
I spoke to AT&T, and they re-assured that the H910 was going to be one of the devices supported after 2022; however, I've been thinking about changing to T-Mobile (my family has a great plan with them, and I always switch back and forth between carriers based on who gives me the best deal) but I can't seem to get a straight answer from T-Mobile about whether my unlocked H910 will work with them after 2021; some didn't even know about the 2021 specifics of it.
I know AT&T will have to allow devices to be used on their network after 2022 even if they're VoLTE capable already. By the looks of it, T-Mobile won't go to that extreme; however, does anyone know exactly how VoLTE works? Specially in regards to using the AT&T H910 model on T-Mobile? Does my H910 has the required Bands to utilize VoLTE on T-Mobile? Or is it one of those things like "Wi-Fi Calling" where T-Mobile Wi-Fi calling only works with the LG V20 model from T-Mobile, and AT&T Wi-Fi calling only works with the LG V20 model from AT&T?
You need band 12 support which H910 has. Also a rom with IMS services working so no AOSP roms.
Volte works by using IMS processes in the rom to route phone calls over IP. No volte = no phone calls. But the device will still "work".
In theory the ATT software will work, unlock it and borrow someone else's sim. In theory a partial cross flash (just system, no modem/aboot/etc) could work if it doesn't.

I was recommended to use an app called Network Mode Universal on reddit for VoLTE testing purposes, and after inserting a T-Mobile SIM card that I borrowed on my unlocked H910 and using the application, the Voice Network Type tab says "LTE". Which is supposed to be a sign that VoLTE might be working on the H910 using a T-Mobile SIM, but that's all I know; just what people tell me.
Update:
The person who recommended that Network Mode Universal app forgot to mention that you have to actually make a call to know whether the phone supports VoLTE with the SIM card in use. When actually making a call, the Voice Network Type tab changes from "LTE" to "UMTS". Which means the H910 is not VoLTE capable on T-Mobile.

Could also be how his sim is set up. Volte has to be enabled there and in the phone. My suggestion would be to force LTE only on the device as well. Does it use VOLTE on his phone?
Also look at IMS registration in the phone and see if it's registered.

The person I borrowed the T-Mobile SIM from uses an iPhone on iOS 13. According to him, the option for turning on/off VoLTE from the settings is gone. He used to be able to turn it on and off at will; not anymore after iOS 13. It should be enabled by default on an iPhone though, I don't see why it would be off. It's almost a necessity on an iPhone I would think.
The LG V20 seems to be more limited in that sense, as on my previous Samsung phone I could enable 2G, 4G, LTE, etc, individually to force only one. I don't see any of those settings on my H910. I don't see any IMS info either.
Either way, I doubt T-Mobile would bother servicing my AT&T branded H910 phone in case IMS needed to be registered; in the case that it wasn't already. I've had really bad luck in the past dealing with T-Mobile on phones that are not T-Mobile branded.

IMS has a phone component and a sim component.
you can check status in the service menu of IMS on the H910. Hope it works on my Tmo phone, getting my sim upgraded

It should work if it's a T-Mobile phone. The H918 is 40% more expensive, so it would be great if the H910 worked with T-Mobile; however, it's not looking good.

Eh, kinda. I'm having trouble too. My IMS services aren't connecting. Going to try a few different roms. I'm through an MVNO so still trying to get them to understand ISIM vs USIM.

Gotcha, I hope it works. I was mentioning to @C D which has helped me understand a lot about VoLTE, that I'm starting to give in to the system of using whatever carrier my phone supports, as long as I can keep using my H910. The removable battery & IR blaster era has come to an end, and I don't think I need another phone right now other than the V20. I might even consider going back to the AT&T MVNO I was using before.

Latest result: oreo works but not nougat.
IMS never registers. Maybe I can fix it. At least now OK sim-wise. Unfortunately doing the sim swap broke tethering.
Hi guys, I am sorry for reviving the old thread.
I too owned H990DS Sea version on latest nougat. It has volte option but just couldn't switch on.
Please take a look at this thread on LG G8
https://forum.xda-developers.com/t/...ther-qualcomm-powered-lg-devices-too.4343655/
I tried on my H990DS using the above thread's method and it didn't work. I was informed that the mbn files are for LG G8. We need mbn files that are specific for LG V20. I have searched up and down and I couldn't find any.
So I hope that I have provided some insights and I hope any member/master/guru out there can help where to find the mbn file (collection of all international carriers mbn) and make volte works for H990DS.
No idea why this started happening but every time I try to make a phone call, it'll hang up immediately. Checked all the settings and nothing has been changed or altered. However, I am still able to access the internet and send text messages. When I try to check my remaining voice and data by entering *777*1#, it'll say, "Connection problem or invalid MMI". It just doesn't make any sense. Contacted Airvoice Wireless and have yet to hear back from them. Has this ever happened to anyone else?
It must be a whitelisted model if it's running on AT&T's network. 4G VoLTE must be enable in hidden settings as well. A new sim card may be needed. AT&T stopped supporting 3G altogether.
Model whitelist (more may have been added since this doc release):

Yeah. My phone's model is whitelisted. I have the H871 variant of the LG G6. After doing some research, it would seem I need a new SIM card (as you mentioned). Nothing I have tried has worked so far. I even went as far as factory resetting my phone. And of course, it did not fix the issue. It's the SIM card. I did access the hidden settings but didn't really pay much attention to the 4G settings. I'm going to go back to that and take a closer look at those options. If there's a VoLTE option, that might do the trick.

That's the problem if it was running on 3G. My Note was running on 4G VoLTE when I got it so the sim card and settings were correct.
4G VoLTE must be enabled.
AT&T advanced tech support can probably help you. May take more than one call to get someone that knows what they've doing though.

I get my service from AirVoice wireless but have yet to hear back from them. What I found out by messing around in the secret menu is that when I choose WCDMA Preferred, everything works just fine. I can call, text, and access the internet. On that setting, 4G is displayed up top. What I found out was that any setting that displays 4G LTE will block my ability to make a phone call. If it says 4G, then I am fine. The problem with this is that everything will reset when I turn off my phone. So, it's pretty annoying having to set it every time. Is there any way to make my selection permanent?

Not sure. The carrier may need to do a reset on their end.
