Unlocked Sprint LS997 on Verizon? - LG V20 Questions & Answers

I am using a Sprint unlocked phone on AT&T and works perfectly. Last night I tried my friends Verizon SIM card and it read everything perfectly. It recognized his phone number, network state well. Does this mean I can use it on Verizon? But when I check the IMEI with Verizon it says incompatible! Any input?

My guess is they don't officially support it but since it supports the right lte bands it will work on 4g but maybe not 3g.... Out of curiosity because I may need to do the same thing in the future how did you get the Sprint V20 unlocked

I used a remote unlock service through ebay.

What version of the software did you have when you unlocked it ?

Tmobile Version has AT&T LTE support, and unlocked bootloader?

So far it looks like the Tmobile S4 has LTE/HSPA+ support for AT&T, and no real signs of a locked bootloader. Anyone else plan on buying that version and unlocking it if the bootloader is in fact unlocked?
Does anyone know of any apps that would test the LTE/HSPA+ bands the phone is capable of? I want to go into a Tmobile and use a test unit to see if I can get service with my LTE AT&T SIM.

Edit: Well, it looks like I'll be getting the Tmobile variant unsubsidized and use it on AT&T. Tmobile will unlock the phone if you pay the total cost up front. I just need to find a replacement back cover to rid myself of the stupid Tmobile logo on the back... lol.

If I had the money to buy the S4 outright for full price, I would just get an i9505.
EDIT: Spoke too soon. The i9505 doesn't support AT&T's LTE bands.
Can you post info on the source? I was also curious about this but i was thinking if we changed the radios like they did in the past that maybe we could get something working?

I put the info in the OP that I have so far; the LTE/3G radios are reported to support all of AT&T's bands. The bootloader, I'm going off of a guess since I don't think that Tmobile could afford to bribe Samsung to lock their bootloaders for them.
HMM, ok thanks for the info so far. I might have to go out and pick one up and test it.
Looks like the T-Mobile version has all the same bands and some extra ones added in. For instance the at&t only has lte bands 4&17. The tmobile version has LTE bands 1,2,4,5,7&17. Will T-Mobile unlock their phones for u??

I'm feeling like a newbie today cause I have my new T-Mobile Galaxy S4 in front of me & still playing with new features after 3 hours.
Tell me how to check to see if bootloader is unlocked and I'll do it.
Also trying to remember where we go to unlock the developer tools. Only remember that it must be clicked 7 times?
Just remembered, Settings.About Device>Build Number <Click Build Number 7 times, back out and Developer options magically appears.
Now i can go into it and toggle USB debugging. Now I only feel 95% newbie.

Has anybody tried their T-Mobile phone on AT&T yet?
If so, I have a couple of questions.
1. Can you use the T-Mobile phone to wireless tether (become a wifi hotspot) on AT&T's network? The AT&T version can be used to tether (with a simple hack). I was just wondering if a different .APK would be needed to do the same with the T-Mobile phone on AT&T's network or if the T-Mobile phone already has an APK installed that works on AT&T's network?
2. I realize an existing AT&T sim card can just simply be placed into the sim unlocked T-Mobile phone for it to work, but how would I go about changing the imei and other phone info that AT&T has in their system about the phone? In other words, would AT&T cause problems with anyone using a T-Mobile phone on their network even if the person paid full price for the phone and it is unlocked? Would it be better to have them change the system information at a store versus over the telephone?
3. It is reported that the T-Mobile phone works fine on AT&T's LTE network, has anyone verified this and does the phone show LTE when on AT&T's LTE network?
Thank you for any replies. Hopefully this information can help people decide if they want to buy the T-Mobile S4 to use on AT&T or not.

You can, for now, use PDAnet for tethering.
As far as changing the phone to appear as "unknown" to AT&T's system, don't do it without a backup of your /efs folder. I don't recommend doing it either because it's not really worth changing things around to hide that you're on a Tmobile phone, because for the most part, they don't care as long as you're paying them your monthly bill. I personally know a friend who has used her unlocked HTC Amaze on AT&T without issue (she was stuck to 2G speeds). The only way for you to have an "unknown" phone on your account is to use an international model phone such as the HTC one or the i9500 (unconfirmed that the i9300/i9500 model is entered into AT&T's system, I only hèard a rumour that AT&T has the IMEI of those phones in its system). My i9100 currently shows up as "unknown" in my bill statement.
I took a screenshot, but I don't have a link of the LTE working conformation (attached). I won't be getting my phone until I am on holiday in New Hampshire so that I can avoid the sales tax on purchasing the Tmobile variant. I would ask my parents to buy it for me, and I send them the money, but they have no technological skills whatsoëver close to asking/knowing what to ask for at the Tmobile store. Sorry guys, lol.

Is Verizon S5 unlocked? Can it be used on T-Mobile?

Hey guys. Is the Verizon S5 CDMA + GSM?
Is it factory unlocked?
Can it be used on T-mobile with everything working correctly (LTE/4G)?
Thanks

I don't know the answer to your question but I can confirm that the Galaxy S5 that I received from TMobile was in fact LOCKED.
I called the support # and was told that I had to have service and use it for 40 days before it could be unlocked.
I PAID THE FULL PRICE ($720 with tax)!!!
I asked to speak with a supervisor -- after 10 minutes on hold -- no change.
I told the store that I was going to bring it back because I didn't pay $700 for a locked phone. Everyone has been nice but it's locked for policy issues and not for technical reasons. I flew to Canada when I bought my iPhone4.
And, AT&T is worse -- one guy told me 3 months and tech support said it had to be active for 6 months.
>> So, my AT&T sim card is not working in my SM-G900T model.
It is GSM/LTE unlocked (as are all Verizon LTE devices), but I'm pretty sure it doesn't have T-Mobile's LTE bands (or at the very least it doesn't have all of their bands).
From what I have been reading, on a Verizon phone, calls and data using GSM and WCDMA bands would work. But LTE bands are Verizon specific hence would not work.
Tl; Dr Voice /data using GSM/WCDMA. No LTE.

Does this mean, once unlocked, T-Mobile and AT&T versions would work on each other's networks including LTE?
I also noticed that with S5, there aren't GSM carrier specific versions. Meaning they are going IPhone route with making all GSM phones enabled that for that country's LTE bands. Is that right reading?

it is unlocked
I am using the verizon s5 on tmobile. It is unlocked and can be used on tmobile LTE. However there are only set modes. LTE/CDMA GSM/UMTS AND GLOBAL. Which means you can't use lte and gsm at the same time (no lte data and voice calls). I usually keep it on gsm, and when I need speedy data I switch it to lte.

How? If you put a TMobile SIM in the phone, or any other foreign SIM, it boots but receives no service. This is in line with almost all other Verizon branded phones (excluding Apple) -- where the phone works (unlocked) outside the US, but won't roam to ATT/TMo in the US.
Pictures please. For the record, my S5 doesn't register on a network with a TMobile or Australian SIM. The Australian SIM in a Nexus 5 roams to TMobile.

This was probably true about a year ago but the recent releases from Verizon, e.g. iPhone 5/5s and galaxy s4 has been fully unlocked world phones. I'm sure there are a few other phones... I think lg g2? I'm not exactly sure. But I have personally stuck my sim(T-Mobile) into my friend's Verizon phones (s4 and iPhone 5s) and they work right away after a reboot. Only problem might be an edit in APN for data and mms. Just sharing my experience, you should check out your phones again.

Not trying to be a jerk, but unless you tried this process in the actual phone in question, then you don't really know if it works. The phone DOES NOT just magically work on TMobile if you put a SIM in, you receive NO service. Now, I didn't go mess around with APNs -- typically those are only for MMS/Data. This is also true for several other phones:
Razr HD / Maxx HD
Galaxy S3
In the past, when the phones were SIM locked, a foreign SIM would prompt for an unlock code before the phone even booted into "normal" Android. That's not the case here -- because the phone is not SIM locked -- but I do believe it is network locked to VZW only when in the US.
For the record, I did try this in my S5. I will be going to Australia next week and will try a Telstra (or perhaps Optus) SIM over there to see what happens.

Yes, I haven't tried it on the s5, but I was pointing out fact that it does work on recent releases which someone confirmed worked on s5 by just plugging it in. I'm also correcting your statement " This is in line with almost all other Verizon branded phones (excluding Apple) -- where the phone works (unlocked) outside the US, but won't roam to ATT/TMo in the US." because Verizon apple does work in the US on T-Mobile and AT&T beginning from iPhone 5. I believe the 4s was still carrier locked.
I was a wireless agent not to long ago, so I know how these things work, not that it magically just works... I'm just sharing you how some recent releases from Verizon has been world unlocked and a few others have mentioned that they just plugged it in and it worked. So good luck and have fun in Australia.

OK Thanks.
It is odd that the apple phones -- and some of the Android phones -- are totally unlocked so that you can use them on ATT/TMobile in the US -- but some (like the S5, apparently) are not. I still am interested to know how some of the other users in this thread got their S5s working on TMobile...
Why would anyone want to buy a Verizon GS5 and use it on T-Mobile? The bootloader is locked and there is currently no unlock method available.
Would you like to exchange?
Would you like to exchange your verizon s5 with my tmobile s5?
i wanted to use it for verizon but the phone is locked to tmobile and at&t.
It would be ideol if i can find someone to exchange it with someone who has a verizon s5 and is looking for tmobile or at&t s5.

I can confirm the Verizon GS5 is compatible with T-Mobiles LTE network I'm using one now with LTE all you have to do is go to settings mobile network and switch to Global mode some times you'll have to toggle LTE then back to global to get LTE to kick in.
I am able to successfully use my VZ Galaxy Note 3 and my wife uses her VZ Galaxy S5, both devices on T-mobile Edge, HSPA, HSPA+ (21mbps), and LTE (band 4) frequencies. These devices unfortunately will not do DC-HSPA+ (42mbps), but that's not a big deal for us because LTE coverage is good where we live. We have no issues with making voice calls, or sending SMS/MMS, and don't have to switch APN's or toggle between Global Mode or GSM/UMTS mode. We leave them on Global Mode with the correct APN settings.
Here's the guide I followed for both (with correct APN settings screenshots to accommodate for MMS on page 4 or 5 i believe):

Did you ever figure out if this was possible? I can't seem to find a definitive answer.
Bump - anyone know if this will work?
As soon as I get mine unlocked I'll let you know as I have Verizon. All s8 models are the same but I'm sure the T-Mobile software has blocked Verizon bands. I'm sure if you flash Verizon software it will work just fine.
I have an unlocked T-Mobile Galaxy S8+ and it does not work on Verizon. I went into a Verizon store and they tried for an hour to activate the phone to no avail. They tried multiple different SIM cards and none of them worked. If anyone has better luck, please let me know. But they weren't able to figure it out at Verizon.

You need an unlocked Tmobile S8 or S8 plus.
Read the instruction in "Flash any carrier 100%" to flash to the carrier you desired, activate all bands.
Then use it on Verizon.
You need to flash your phone to Verizon to work. I did the exact opposite actually. I bought a Verizon device and flashed it fully to T-Mobile. Works perfect on T-Mobile because every US Galaxy S8 for the major carriers is SM-G950U. They support each other's bands, their just disabled by the carrier firmware.

I did not have any luck flashing it to the official Verizon Firmware, but I was able to flash it to the G955U1 firmware. The official unlocked US Firmware. Make sure your t mobile device is SIM unlocked by TMOBILE before you do this.
1. SIM unlock device by tmobile (pay off device, meet the 40 day requirement, etc).
2. Flash to G955U1 (S8+) or G950U1 (S8).
3. Insert Verizon SIM or ATT or any SIM.
4. Your phone will give you pop up warning saying it needs to restart to configure the new SIM.
5. Enjoy your new carrier.
Did you use a Verizon SIM and did you get both VoLTE and WiFi calling to work with the G955U1 FW?
my 2 cents

I went to Verizon store and used one of their Verizon SIMS from a display model of the S8+. Voice over LTE works, Data works and I was not able to test Wifi Calling at the store. I even ran a speed test and had about 27mpbs down and the associate ran speed test on his phone and he got about 20mpbs down connected to the same server using the Speedtest app. I ran the LTE discovery app and shows me connected to LTE Band 13.
Hope all of this helps.
Bringing S8 to sprint?
Did you anybody try to use a TMobile or other branded S8 on Sprint? The Sprint customer support is not able to add the IMEI to their database for whatever reason.
@Aephel 
 @T33H00
Silly question, but does doing all this void Warranty? or is there no such issue anymore?
For example flashing Verizon Firmware onto a Tmobile Unlocked.
I unlocked my t-mobile s8 plus and attempted to use a Verizon SIM. It does NOT work. Verizon states that the IMEI is not in there database and that they cannot activate it.

Possible to use a Sprint HTC 10 on Verizon with unlimited data & hotspot?

Hi all,
I didn't see anything from reading through the forum on using a Sprint HTC 10 on Verizon. It sounds like there's been success with Tmobile and AT&T.
So far, this is what I've found:
-Sprint HTC 10 should have all the LTE bands necessary for Verizon
-Sprint HTC 10 needs to be sim unlocked before anything can be done
-S-Off + root are required for any potential workaround for Verizon, as the appropriate radio needs to be flashed
How far off base am I? I am intrigued because I am on Verizon and I'd like to take advantage of the sprint HTC 10 sale that's supposedly going on right now. Thanks in advance!
I have the same question. I'm trying to jump on that but for T-Mobile. I'm just worried I won't be able to get the device unlocked.
Historically, Verizon and Sprint don't activate each others' phones. They're the two big CDMA carriers that don't use SIM cards, but activate by ESN directly. But there are always those who get lucky.

I've been working on that recently. I actually want to be able to switch between Sprint and Verizon.
Sprint has to activate both the phone and the SIM. Verizon has moved to just using SIM cards. I've been able to move a Verizon SIM between devices and have everything work, even on devices that aren't official Verizon devices and even some that only support part of the bands Verizon uses and work on the ones they support.
With the HTC 10, I've been able to get S-OFF and unlock the phone myself since Sprint wouldn't do it. When I put in my Verizon SIM, it recognizes it but for whatever reason is unable to connect to anything but 1X Roaming (probably on Sprint but it won't say). Poking around in CDMAtool hasn't helped much.
I'll update this if I ever figure it out.
Any updates? I'm curious myself. I have the Sprint HTC 10 and am working on finding an MVNO that I like, some of the Verizon ones are tempting.

I got s-off and then unlocked via one of the methods here in xda. Using on t-mobile perfectly. No issues.

By perfectly do you mean volte and Wi-Fi calling are working for you? If so please point to the guide you used. I can't find where anyone using a sprint 10 has gotten those things on T-Mobile.
I would be surprised if a sprint 10 used on Verizon would have that work too but haven't seen any mention of it.

I unlocked the bootloader and installed ViperRom, picking the US Unlocked version as my device. I have working VoLTE, but not wifi calling. (Note, this is on Mint Sim, which uses the T-Mobile network)
yeah it would be great if someone could give a for sure answer to this. I've found a lot of post giving conflicting information all over xda and r/htc10 about this. I would love to buy a used sprint htc 10 (seems to be the cheapest version by far) and use it on a verizon mvno, but until I know for sure it works I' not going to do it.

activate ATT v35 on sprint or any cdma mvno

tried to run the imei number on the sprint and verizon site, says cannot be activated. Went to sprint and called verizon, says att branded phone cannot be activated. This is unlocked, works on tmo. tried searching for a solution in the forum but no dice.

Doesn't matter if it's "unlocked", other carriers have their rules for what they allow on their networks. Most AT&T phones don't have CDMA, and Sprint, Verizon (for now) still uses CDMA.
On non-branded phones you won't get VoLTE from most carriers (T-Mobile is the exception) and without VoLTE you would need to temporarily drop down to CDMA for voice calls on Sprint and Verizon.
Even on phones that have CDMA, like the LG V30 US998, Verizon still wants you to buy their branded phones -- because end of this year when CDMA goes away, those phone still won't have VoLTE. So in a few months those phones won't be able to make phone calls. I have two relatives with LG V30/V30+ US998 on Verizon. Don't ask how, there are ways. But even of 2020 they will need new phones when Verizon kills CDMA and they can't get VoLTE on non-Verizon phones.

As an owner of an AT&T v35 I can tell you it will work nicely on the Verizon network including VoLTE and VoWIFI. You do have to jump through a few hurdles. You will need a SIM activated on the Verizon network. That may mean buying a new phone from Verizon. You also need to SIM unlock the v35 by buying a code from a site like codes2unlock.com. You may also need to cross flash to the NA rom. These things should be done in that order, and there is no going back to an AT&T rom afterwards.

Chazz, can you clarify this? I have a US998 v30s running on Verizon with VoLTE. It was my understanding that it will not be affected by shutdown of cdma by Verizon. I like the phone and want to continue using it.

My brother-in-law found Verizon store rep willing to break the rules for he and my sister's USS98 V30+ (converted from Sprint LS998). They switched from AT&T to Verizon.
This guy said "Verizon wants you to buy their phones, of course. They'll tell you this phone (US998) won't work, but it will." He activated two SIM cards and put them in their US998.
He said "If you have any issues, ONLY see me here at this store. Don't talk to any other reps about this." Wink, wink, nudge, nudge. (Monty Python reference.)
My brother-in-law and sister don't have V35 on Verizon, but you probably have VoLTE because you enabled VoLTE on another phone (Droid Turbo)? I don't know if they have Verizon VoLTE on US998 V30+, but I assumed they didn't...

If you have Verizon VoLTE now, then nothing will change.
I assumed my brother-in-law and sister don't have VoLTE and are temporarily dropping to CDMA for phone calls. But I have no way of easily checking. Neither would know what "VoLTE" is nor "CDMA".
I merely told them their US998 phones were carrier unlocked and would work on Verizon -- if they got already-activated SIM cards. My brother-in-law used his considerable sales skills and found a helpful rep.
thanks a ton @chazz for the clarification. i have already move to AMZ 9.0 which looked to be pure android. was not able to get NAO due to error(sha256 auth error). AMZ was the only one that worked from multiple different firmwares(lgfirmware /sammobile) from us region and it works awesome.
For the verizon sim card, can i buy flip phone or a throw away verizon smart phone with the activated sim card and use it with the v35. similarly can you use the approach for sprint?
Again your response is much appreciated.
You should consider features you want to have on your account when buying the phone from Verizon. Some can be toggled through the the settings menu on the v35 like Advanced Calling for VoLTE, but others can't like visual voice mail. Ask to have them activated when you buy the phone. Keep that Verizon phone, you may have to get help in the future from Verizon and it will come in handy! They won't be impressed with the v35.
I don't have proof of it and am not in a position to test, but I suspect you cannot activate a Sprint sim on a Sprint phone and then move to the v35. My understanding from reading about the open market ULM and AT&T branded v35 is that Sprint maintains an IMEI whitelist. Sprint only allows Sprint branded phones on their network. This is why the ULM model is preferred for Google FI.
Please post what you learn so others can benefit.
