"Unlocked" Verizon Samsung Galaxy S4 to Tmobile switch - cannot send text messages
Please! HELP!!
I switched from Verizon to Tmobile and my stupid phone updated to Lollipop 5.0.1 and now I can't send text messages without calling Tmobile and having them send a signal to reprovision my phone EVERY time after it reboots (which I have to do EVERY day now that bluetooth sucks so hard and randomly stops all the time in Lollipop).
Before I accidentally hit the button to update, my phone would show my Verizon voicemails waiting in the notification area and say "No Service" until I called my voicemail and let it disconnect, to which effect it would seem to go to no signal to nothing to HSDPA to plus to 4G LTE and BAM! I'd be on Tmobile able to send texts and all (before which I could NOT send texts, but COULD receive them (IIRC), and make phone calls (WITHOUT dial tones being accepted (which seemed to be fixed in Lollipop by selecting long press tones in the phone settings), and I COULD browse the web, etc.).
NOW, that little workaround does NOT work anymore and I have to call Tblowbile to send that magical signal to my phone (which doesn't seem to take all the time for all people for some reason).
I DO have the APN entered correctly (as stated on their website) and setting the phone to and from global to global/lte/gsm and selecting tmobile as the mobile network in the settings does NOT work.
I GUARANTEE it is that stupid GRAYED OUT Verizon APN that I CANNOT remove that is causing ALL these problems (given the nature of the phone post-reboot on KitKat).
PLEASE, tell me how to delete that stupid VZW APN or how to downgrade to KitKat or of another workaround other than having to call the deceptive, bait and switch company that is Tmobile EVERY time!
I'M DESPERATE!
PLEASE, HELP!
You can't. The bootloader is locked on Verizon, which prevents root. They've also apparently blocked access to the APNs in firmware.
Your options? Head to the XDA Verizon S4 forums and check out their various guides.
P.S. T-Mobile is not pulling a bait and switch here. They are providing you with service, which is what you paid for. They have no control over the OTA function of the device. Unless you have proof that T-Mobile is baiting and switching, your comment is slanderous/libelous.

I have the Verizon model of the S6 Edge+ (SM-G928V) I want to know if it's possible to flash it with the t-mobile rom??
I currently have a T-mobile MicroSIM that i put into the verizon phone. I had to configure it with the t-mobile APN to get calls/text to work. Currently I have a few issues:
1) I can make & receive calls, send & receive texts, but CANNOT send mms, but i can recieve mms sent to me. (I tried to see if enabling wifi would make a difference but it doesn't)
2) I get an annoying message anytime the phone reboots that says I'm not using a verizon wireless SIM. (if anyone knows how to get rid of that, great. if not it's not such big of a deal)
3) How to remove the Verizion boot loading screen??
Do I run the risk of bricking or tripping knox if i try to use a t-mobile rom on a verizion phone? Or does anyone know how to resolve any of the issues i'm having? Any help would be appreciated, thanks in advance. (and No, just getting the t-mobile version of phone is not an option for me)

You cannot rom that phone because Verizon nazis lock all bootloaders on all their devices. As for the sending mms you'll probably need to take it to a t-mobile store and have them sim unlock and flash their full apn. That should do it but I can't say for sure since I've never used a Verizon phone on t-mobile
So just to update: The issue with not being able to send mms messages is because of the Message+ app that was set as default messaging app (factory reset setting). When I changed the messaging app to the "Messages" Samsung app I'm able to send&receive mms with no issues. (Please note the proper APN settings must be set)
The other issues such as the loading screen and the SIM notification I'm not too worked about, but if you have any help on those that should be great.
The only *real* issues with using t-mobile sum card with vzw phone is that the service isn't all that great, I seem to have 3g in some areas where I can't send mms while on the phone, but other than that it works well on an unlocked phone.

I believe the radios in verizon phones don't cover all the band's that t-mobile uses. However t-mobile phones tend to run pretty well on Verizon so your signal issues will continue until t-mobile launches band 12 in your area, which is the primary band that Verizon uses for Lte
Samsung lists band 12 on their site for the Verizon S6e+.

I own a SM-G935V that I'm using with Tracfone. It's running 7.0/Nougat, patch level 4/1/2017. On another forum, here's what I wrote:
I've run multiple tests on this and it turns out that if I reboot my phone, I do not get reconnected to cell service unless I make an outgoing telephone call.
The reason why I didn't notice this is because I use Google Voice for about 99% of my SMS communication. So here's the test I ran:
1. Reboot phone, wait until it comes back online and I have bars and 4G on my status bar
2. Call my phone from another phone -- goes straight to voicemail
3. Send SMS via phone's SMS -- goes to pending and is never sent
4. Make an outgoing phone call not using Google Voice but my cell network resolves the issue
I've changed the network from Global to LTE/CDMA, but it makes no difference. I've also turned off the wifi and tried to see if I would be denied for data access, but that is not so -- I can visit websites without any issue. But doing that DOES NOT reconnect me to my cell network. So it seems that since I'm using 4G/LTE for data, that authentication is separate from the cell authentication.
I got a response from another user that's experienced the same issue. He said he had no problems with Verizon prepaid SIM but the same exact thing with a Tracfone Verizon-piggybacked SIM. His solution was to push an unbranded firmware on it.
I'd rather not go this route if I can help it since the phone works well and this is the only issue I've encountered. Any suggestions?
Hello. Moto g5 plus unlocked 32 gb from amazon, no prime ads. Unlocked bootloader, custom Validus 8.1 rom and TWRP recovery. Was previously with Redpocket Mobile, switched to Verizon prepaid ($40/month plan) and received my 4g LTE sim card yesterday and have been having nothing but problems since then.
TO start, the sim took a long time to register my number, and "program" itself as Verizon called it, this is because I finally figured out even though Verizon claims excellent coverage in my area (49783 U.S) I currently have barely any service, so that's why it took forever to register/port my number over.
SO now I can hardly even send a text with the stupid thing, it's resting on 1 bar and then usually disconnects frequently and says "no service." When I go into town I get 3/4 bars of 3g , not 4g LTE. I was curious as to why this happens, so I spoke to a friend who has Verizon in my area and he said it's a deadzone for verizon where I live, but that he gets 4g LTE everywhere else in the city.
Does anyone here have a Moto g5 plus US version (no indian/foreign versions) PURCHASED in the US and on the Verizon network? Also, my friend is on postpaid network, not prepaid, not sure if that makes a difference. IF anyone's with Verizon here can someone confirm it's compatible? It shows up on my Verizon account as XT1687. I got this plan for the extra data and rollover/hotspot capabilities that redpocket DIDN'T have, but if I can barely even send a text message at home what's the point? I have been on the phone with Verizon for hours and they claim my phone is compatible but that they "cannot guarantee coverage on phones not purchased from them" or something like that. Does having a custom ROM affect coverage in any way?
Couple more symptoms to help you guys diagnose my issue: In settings > about this phone > sim status, when I click mobile network status it usually "refreshes" so if it had listed one bar previously, I tap on it and it will say "no service" which to me indicates tapping on it updates it, and that the phone is constantly losing signal. Also, I keep getting messages about leaving service and roaming, though roaming is turned off.
What I'm most intrigued about is I can make calls from anywhere in the house unless the phone says "no signal" so even if the phone is on one bar and listing x1 for service or 3g, a call will come in or go through fine, but MESSAGES WILL NOT SEND. In android messages, it says "tap to send again." Which is weird because if a call could go through certainly a simple sms would?! I still have yet to test service in the heart of the little city I live in, I've only been outside of my house and in, so I haven't extensively tested different areas yet, so I'm not giving up yet!
Finally, what APN should I use? It's set to "straight talk verizon" right now, but there's a bunch listed. Perhaps other Moto g5 plus users could confirm which one they use? I suppose it sets itself by default...
thanks for looking through and please answer my questions! I need more competent help than Verizon can offer.
Just as the title says, has anyone successfully used an unlocked, Verizon branded LG G6 (VS988) with a third party sim (for data and making phone calls? Which country are you in, which sim cards are you using, any attempts abroad/traveling, etc?
Bought a mint unlocked Verizon LG G6, confirmed it was unlocked by two Verizon reps over the phone, and one in-person Verizon rep in my city. With the in-person rep (as well as on my own of course), we could not get my T-mobile, Three (a UK sim), and Project Fi to work with the phone, for data/phone/SMS.
Not surprisingly, when he inserted a Verizon Sim, of course it worked. The rep genuinely tried his best to help, but in the end was like "sorry, ¯_(ツ)_/¯ " and said it was probably an unresolveable network problem, and yes, that the phone was definitely unlocked (checked his database).
Before I came to his shop, though, I spent a couple hours at home tinkering with ALL the phone settings (set up a verified APN, toggle global/LTE-GSM-CDMA options, set data roaming ON), and the best I could get was the G6 successfully connecting to T-Mobile for all of 30 seconds (I could surf the web, but NO phone calls), then losing all bars of connection and cutting out entirely. Toggling airplane mode allows you to connect for at most 30 seconds at a time, also, weirdly enough.
What gives? I confirmed the sim cards worked on my other unlocked devices (LG G5, 1+5, Xiaomi Redmi), and I really want to use this G6 here (USA), but more especially, while I am traveling abroad and looking to use whatever country's local sim cards.
Lastly, do you think rooting this phone and installing a custom ROM would help the issue? I prefer not to return this phone because I got a decent deal on it (through ebay's 20% off) and everything else about it is awesome.
Hi
While not strictly the same, I have Verizon LG V20 VS995 with a similar problem with my EE sim which will not register properly and when it does it is only 3G instead of 4G/LTE but keeps dropping off. Where I differ from you is that I can use an O2 sim and get both calls and 4G/LTE data with it. I live in UK. Hope this might help.

My G6 is the unlocked us997, but the wifes is the Verizon Unlocked G6. UNFORTUNATELY I have yet to get her MMS messages working on it for her but everything else works perfectly fine, on TracFone sim (on AT&T network), ... And FYI, only the bootloader unlocked LG G6 can be rooted, all the carrier version, whether they're network locked or unlocked, they're most definitely bootloader locked, thus no root :<P
I got the same phone as you...I live in the Dominican Republic using a Claro chip...Bought the phone from ebay unlocked. So there is something you must talk with verizon so they unlock it. On the other hand we cant root our phones only the europe and US version can be rooted.
Have you checked if this phone has a region locked on it? And if it's removed by placing that 5 minutes-long phone call?
Also, once the SIM (non-Verizon SIM) did you check the APN settings if they are the correct one for your carrier?
I have a similar problem
I bought an unlocked Verizon G6 vs988 on ebay (the listing actually said US997).
I managed to get it to work for phone calls and sms but could not set the data.
I manually set the APN but it would not stay "chosen".
I got all the settings but when I chose it and closed the screen it got unchosen (unchecked) and I did not get a data connection.
is there any custom rom for this model?
would a firmware for the us997 work on this model?

If you are in U.S. it should work fine with AT&T and T-mobile, as long as correct APN has been entered. once you enter the new APN, you must select the 3dots, on top right and save, once the new SIM inserted, just go back to APN and select the correct APN.
If you are outside U.S, the LG G6 Verizon unlocked does not have B1 (2100) which is required by most GSM carriers out side US, so you can get 3G or in most cases 2G (E) network only. LG G6 AT&T unlocked works fine outside US, but it does not have CDMA technology and can't be use with Verizon or Sprint. hope that helps
Hi , I have a similar problem. I bought vs988 verizon version and popped in a MINT sim. I had issues setting it up but eventually got it work via the pull down menu in the 'settings' at the top that said 'mobile data off - turn on?' - now this has vanished- can I get this back ?
The mobile data button in the notification tab and the actualy mobile button in the mobile data section in 'settings' do not work (and never have) - they always ask me to contact verizon.
So what do i do ? I have no mobile data now. And it's a pain.
My issue is partially solved in that when I 'reset network settings' and then re-add my APN (for mint) it automatically turns on mobile data. Using the other 'mobile data' buttons (as I mention below do not work).
And now that mobile data is on - I use airplane mode to turn it off, and turn on wifi (because i have google voice I still get voice calls). Anyway this works if you have a similar problem.
I am wondering if this issue would exist if I used a Verizon MVNO (instead of Mint/t-mobile) ?
(so by it being offically "unlocked" actually is not really true - when i first bought the phone I messaged LG and they suggested i needed to send it into them so it could be re-flashed. They would charge me for it and I would lose my phone for about 2 weeks - which is a pain, and not worth the expense)

I have the verizon version of lg g6 and it works perfectly fine in Nigeria with all nigerian sims:mtn,airtel,glo,9mobile and even works on 4g let but I set the network mode to global and I receive calls and sms promptly
Okay so I have been fighting this phone for months now. I am so ready to just sell it to some phone trade-in company for $175. I am at a complete loss.
My father-in-law ran over his SM-G935V (yes, Verizon) with a golf cart and broke the screen and back plate. He then gave me the phone so I could fix it and use it. I replaced the screen and back cover on it and ordered a verizon sim card (I was on straight talk BYOP program using an ATT sim card) I activated the sim card and it didn't work on this phone. It just said, "Searching for Service". I put the sim card in my Moto X (Pure Edition) and it worked fine and had full signal. I took it back apart and made absolute sure that the antenna and every other connectors that I unplugged were seated and connected properly.
Seeing all the verizon bloatware and that it was on 6.0, I then thought it may be a software issue so I decided to get the G935U 7.0 factory unlocked image from sammobile.com. I waited for like 4 hours and downloaded both the unlocked version and the Verizon version. After using odin to flash both of them (one at a time of course) neither worked . The flash did work perfectly in every other aspect and the phone is now a G935U. I still have the original problem, however, where the phone shows "no service" and wont connect to a cellular network. It auto configures for what ever sim card type I put in (verizon, ATT ect) and connects to Wifi.
I'm so done with this thing.
Any suggestions?
Thanks guys!!
I have the same problem, I haven't find any fix to this error...
I didn't have much money into the phone so I sold it on one of the phone trader websires for $180.
Case closed haha
No service message
I'm using smg935v with straighttalk byop sim card.. every time I restart my phone it says searching for service.. no text messages or incoming phone calls can be recieved. However, if I open the phones dialer and attempt to complete any dialed number.. Verizon wireless reappears and full phone functionality returns. I realize this is way late on your post and this probably doesn't matter.. but this may help anyone else experiencing this issue in the future.
I have a Verizon Galaxy S7 Edge G935V. I use it on Straight Talk with the AT&T sim card I took out of my Nexus 5.
I had to go into the settings and change it from CDMA to GSM. There is another choice called Global.
I tried both GSM and Global with same results.
Next I went into the APN settings and added a new APN. I entered all the information required for Straight Talk.
The phone is working fine except for 2 things I noticed. The verizon s7 Edge is missing LTE Band 17 and I think 12 too.
In my area Band 17 LTE is what my nexus 5 would connect to verified by an app called LTE Discovery available on Play Store.
On the S7 Edge it doesn't get Band 17 LTE. Fortunately I can connect to another band but its not quite as strong but it works.
I can surf, text and send pictures. When sending pictures I noticed the messenger program (default) isn't reducing the size of
the pictures small enough to work with text messages. I struggled with this for a week until I tried an experiment.
I used an app called Photo and Picture Resize. The App lets me take a picture, resize it and then send it with the messenger app.
Once the picture was reduced it sent fine. My nexus 5 never had this problem.
The other thing I noticed is sending a video text results in terrible quality. I have tried the lowest resolution
to the highest resolution setting with no improvement. I did a search on this and others seem to have the same
problem with the other versions of the S7 Edge, S8 and S9. I would like to find a fix for that.
The straight talk site offers the correct APN settings should you not know what the are.
