Verizon: Global Roaming Problem (on return to USA)

I've been tracking and testing a bug where if you activate your N6 on Verizon, then switch the SIM to another carrier (say TMO) to test your phone will not re-connect to VZW when you put the original SIM in. This happens if you change the "Global" setting the LTE (Recommended). After you set that on TMO (or AT&T or...) the options menu only gives you 2G/3G/LTE where when activated on VZ gives you "LTE/3G/1x/Global". The only way to get the phone back on VZ is to factory reset.
Today - I just came back from a trip to Canada where in Global mode the phone roamed on one of their GSM based carriers. I didn't change the roaming mode out of Global (I know better) but when I was back in the US the phone wouldn't go back to VZW - instead went to "Emergency Calls Only" I checked the carrier settings and in the time I was in Canada (2 weeks), the Global option disappeared, leaving only 2G/3G/LTE...and no Verzion. It was done. Factory reset time.
Hope they've spotted this issue in their "intensive" testing process and that's why they are holding up the release. If not..be prepared if you roam globally on the N6 to have a dead radio when you come home and factory reset.--unless there is a service/app settings that can be easily wiped...

I had the same issue (my thread is in the Q&A subforum). Nothing short of a factory reset would fix. Hopefully Google gets on this and fixes it. I travel overseas for work frequently, and the whole point of getting the Nexus 6 was so I could use one phone here and there!

I'm on ATT using a GPS version phone, and I noticed in the "Preferred Network Type" my default setting was on "Global". But it only has choices of "LTE (recommended)", "3G", and "2G". So if I switch to LTE, I have no way of changing back to Global.
Subscribing to thread for a fix.

Can you not change the network type in the *#*#4636#*#* menu to "LTE/GSM/CDMA auto (PRL)"?

I just switched back and forth. Not sure I understand what is going on here.
Edit. Ahhh but you also switched carriers, interesting.

well thats a bit concerning... I'm leaving for taiwan in a couple days and was looking forward to just dropping in a sim over there.
So even with 5.0.1 you cant go back to VZW without a factory reset?

Okay I just got back from a trip to Taiwan. I switched to 2 different carrier Sim cards.
Upon returning to the states, I popped in my Verizon sim card and everything works fine.

Yeah, just do the *#*#4636#*#* and change the network that which you'd like to connect. So for Verizon, you would choose CDMA/LTE in the drop down menu. Once you do that, your network options in the regular settings will change.

Same thing happened to me on a recent trip to Spain. I made a backup before traveling and upon return I flashed the backup to get it to work again in the states.

Has anyone seen any updates on this? Is Google aware of this bug? I'm using my Moto X overseas since I don't want to factory reset my Nexus 6 when I get home. This was the whole point of getting a Nexus 6 in the first place: I could use the same phone here and home with a simple SIM swap!

Has anyone tried
fastboot oem config carrier vzw
to see if that will "jump start" the phone back to Verizon?

That did nothing for me. Tried it earlier this week

Those with the radio issues could try to flash only the radio.img using fastboot. This would let you restore the radio without having to wipe the entire device. Hopefully a fix will come when Verizon officially releases the Nexus 6.

My solution was to pop in an active T-Mobile sim, turn the phone on, and then back off, and then pop in the vzw sim.
That seemed to solve the problem.

Interesting. Wonder why a US GSM carrier would fix the problem, but a foreign GSM carrier causes it. Maybe I'll give that a try next trip (in 2 weeks).

I don't think its the matter of a foreign GSM carrier causing the problem.....
I think the problem is Verizon.
I don't hear of this issue with anyone else but Verizon customers.

I doubt it, since the inability to switch modes is present even before the Verizon SIM is inserted. I think it's a bug within Android itself.

I just tried this exact same thing after being in London and Budapest. My Verizon SIM in my Nexus 6 wouldn't register on their network. I put in the T-Mobile SIM and it did work and register with no problems. Switched back to Verizon's SIM and no luck. Still not able to register on the Verizon network.

To clarify, the verizon sim roamed onto canadian providers without problems. When I returned to a normal Verizon service area, the phone wouldn't register again (on verizon) until I popped in a t-mobile sim, and then switched back to the Verizon sim.

Yes, that's what I did. Went to London/Budapest with the Verizon SIM roaming. Landed back in the States, no more Verizon connection on the Verizon SIM. Popped in the T-Mobile SIM and it works perfectly.
Tried doing the switch back like you mentioned, but no luck at first. Had to try a few times. Back to life now.
Thanks very much.

Uscellular g4 with tmobile sim

I dont know if anyone else has tried this but i popped in my tmobile sim into my uscellular g4 and had service the only thing i had to add was the apn

This is without a sim unlock bought the phone 2 days ago and been using it was going to get a sim unlock but apparently it works just fine without it on tmobile.

Just to show that its a uscellular g4

Are you getting full speed LTE?

Yes doesnt seem to be a problem only thing i noticed is it wont let me make calls and or text but it will let me use data

When i make a call it tells me its an incorrect sim so i think if i unlock it will allow me to make calls and texts but as i said previously itll let me use data no ptoblem

I had heard that some CDMA phones may not allow phone calls or texts, you should look into finding a way to disable the CDMA, it may or may not work.
I think calls and texts are going through the CDMA and not GSM.

I have to agree i think if i sim unlock it that it will allow me to bypass the cdma part of the phone uscellular said after i pay the phone off i could get the sim unlock for it

No need to sim unlock, it already is, most new phones from verizon are already sim unlocked and some other carriers as well, only help is probably trying to disable the CDMA in the hidden menus and probably enabling gsm.

I agree with @Arctic Prodigy, you should be able to make calls texts, just by changing something in Settings. On my One Plus for instance (the only device I have handy, sorry) go to Settings > Mobile Networks > Preferred Network Type and then change from CDMA or whatever it is set to, to GSM/UMTS or something similar to that if it's available. To reach this menu on your device it may be slightly different in Name or location but it should be there somewhere. A friend of mine had a VZW s4 and I told her she could use a straight talk sim in it. She had issues at first but I do remember I changed this setting I mentioned above from whatever form of CDMA setting it was on to GSM and it has been working fine ever since!
I would think if it were sim locked, then you most likely wouldn't get data after setting Apn. This tells me it sees the tmo sim and that you have active service, so it is allowing phone to use the data connection.
Hope this helps!

It has these and i changed itto global and gsm/umts and still vouldnt make calls or texts

It tells me when i make a call its an invalid sim even after changing it to global or gsm/umts

But like i said it lets me use data so ill have to do some digging i used to dev for the note 4 so ill have to learn lg's a little shouldnt be to hard

I know the T-Mobile iPhone 6 has CDMA as well but it is disabled, regardless of changing in the settings to gsm/umts it still maybe trying to go through CDMA, you need to disable CDMA and enable gsm in the hidden menus and if you get it to work that way you may need to reset it if you reboot phone.

The problem is i havent been able to ascess the hidden menus ive tried all the known lg hidden menu codes

I am positive it will happen soon, I have seen a posting somewhere here for the hidden menu but it still might not be accessible just yet, but a developer will get it soon enough, I know for the LG G2 or G3 the CDMA phones all have been patched to get gsm. It's only time now.

Well if i can put a few heads together that have a uscellular G4 im sure we can access the hidden menu for the uscellularG4

Try 277634#*#
Also found this link http://androidforums.com/threads/how-to-turn-4g-on-off-access-hidden-menus.638374/

That doesnt open anything at all for me

It seems to be working only on some of the G4's but not all.

Verizon compatibility broken after update?

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.

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?

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.

S7 Active - Switch From AT&T - Confirmed Working

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.

Dial *#*#4636#*#* -> 'Device Information' -> 'Set Preferred Network Type:' -> Select 'WCDMA' or 'Global auto (PRL)'
My phone worked fine in Sweden with default settings, but in Romania I had to type in the above and chose LTE/UMTS auto (PRL) and then it worked perfect!

i have an s7 active that was frp and network unlocked. i am trying to use this on tmobile.
my s7 active is running android 7.0
i have a few problems and need assistance
1. the wifi calling option is greyed out under settings. from the home screen using the pulldown menu the wifi option appears to be turned on.
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

H918 (T-Mobile) - Is it carrier unlocked?

Hi everyone.
I bought a V20 T-Mobile version H918 on eBay. Seller claims it's carrier unlocked. As a precaution, I bought a $10 Red Pocket prepaid SIM card to test it with (because my current phone is CDMA). First, I tested it with Red Pocket's "GSMA" sim card, which uses AT&T's network. When using this SIM, the phone mostly didn't work. Out of 30 tries, I was only able to make a phone call once. All other times, I got no dial tone. And I wasn't able to receive data at all. APN settings were correct, verified with Red Pocket customer service; also tried many other APNs I found on google, but they made no difference.
Next, after doing a factory reset, I tried Red Pocket's "GSMT" SIM card, which uses T-Mobile's network. When using this SIM, all services including calling, texting, mms, and data work perfectly. Although, despite it working, the phone is using the wrong APN (fast.t-mobile.com). This seems to be a hard default setting, and the phone doesn't allow me to select a different APN while this SIM card is inserted.
Red Pocket tells me that an unlocked phone should work fine with either the "GSMA" or the "GSMT" card. So, their advice, together with the fact that the phone isn't letting me change the APN when on T-Mobile's network, leads me to believe it might not be unlocked. How can I know for sure?
Note: IMEI registers as clean in the database. Also, the IMEI in settings, the one shown by dialing *#06#, and the one on the sticker all match.
Thanks!

If it was locked, I don't think it would have accepted the ATT sim at all. You can try playing around with the Device unlock app, but on the first screen it seems to pretty much always claim its locked for me
On my (pretty sure its unlocked, havn't stuck another sim in it almost since I got it months ago)
H918 that's running on a T-Mobile (proper, not mvno) sim I can freely add and switch between APNs
Keep in mind that the H918 isn't going to be good on ATT's network.

Thanks for the reply. You're saying if it were still locked, it would give an error message with the AT&T SIM?

right, if it were locked, you wouldn't even get 1/30 phone calls to work, you'd get like invalid sim or something. Locked means it wouldn't even try to use the other sim.
Happend to find a video of someone with a simlocked h918 unlocking it, it shows networked locked where the carrier name goes.
