Use Verizon S9+ on T-Mobile - Samsung Galaxy S9+ Questions & Answers

Sorry if this has been asked and answered, I was looking to switch from Verizon to T-Mobile. I have an S9+ and my SO has a Note 8. Got the SIMS on the BYOD, popped hers in, it detected the SIM, restart, and bam. All the software and what not is there.
Pop mine in, nothing. Restart, nothing. No software, no settings. The device is unlocked (Verizon says all 4G are unlocked.) I get the "Sim card is not from Verizon." Am I missing something?
What a pain in the ass. T-Mo said I'd have to download all the software. Yes?
My kid has an S8, we got the Sprint deal, popped in the Sim, installed and setup without delay. Only my S9+ has drama.
Ideas?

Mine worked fine, it selected the TMobile apn on its own. Maybe you can go to apn and change to tmobile or add one?

I have the Galaxy S9 Plus U. S. Unlocked version. When I first purchased it T-Mobile was my carrier, I popped in the new T-Mobile SIM and everything set up automatically, I tried Verizon when I popped their Sim in everything set up automatically, currently I'm running ATT when I put my ATT Sim in everything popped up and set up automatically. So, maybe there's something wrong with your sim card.

Unlocked Galaxy S: Your sim card does not allow connection to this netowrk

My Vibrant just stopped working...
My Vibrant is unlocked (purchased code from a site) and was working fine for a week (got it 2 weeks ago). It's rooted and I flash a few roms and modems to test out what i liked. Yesterday, it decided to lose signal. I wanted a few hrs and still had no signal. I tried searching for a network. AT&T showed up and when I selected it, I got "Your sim card does not allow connection to this network". I've tried flash the modem, then the rom, and even tried restoring it with Odin. Non worked. I then tried a TMO sim and i got signal, but can't dial out...
Please help! I've search and haven't had any luck fixing it... Thanks in advance.
Usually when you flash a rom, it may wipe the folder containing your unlock code. Redo your unlock with the same code you purchase

Yes I'm on AT&T. What do you mean by load the network? I've been to the network/wireless settings and have the "AT&T 310 410" APN selected. When i do a network operators search, Automatically doesn't fix it. When i do a "search now", AT&T shows up and when i select that it says "Register on AT&T" and then i get the "your sim card does not allow a connection to this network"

I ran into the same problem last week. My Vibrant was working in the morning, and then it gave me the same message a bit later on the day. I couldn't figure it out for the life of me. I contacted TMobile and they told me it could be a bad sim. I was taken back by this, as it was working earlier in the day. I ended up going to a TMobile store and got a new sim. It worked after the new sim was inserted.
Maybe you can get a new sim with ATT.

I popped my friends AT&T SIM in and still had the same issue...
I'm thinking of just getting a prepaid SIM and testing it out. That should be the same as getting a new sim, right?

After the trouble shooting didn't work, TMobile gave me a free sim card. She noted my account and told me to go into a Tmobile store to get one.
I won't pay for a prepaid just to test it out...Can you contact ATT
I talked to AT&T yesterday too... Tech said its the phone... contact the carrier/maker of the phone... They don't really help you unless the phone is AT&T branded... guess I'm SOL and might need to just sent it to Samsung for repairs... =T
Update: I flashed everything back to stock JI6 via odin. Just tested on my friends TMO sim (he has a vibrant also). It finds the TMO network, but can't dial out. After a few min, no signal...
Im having the same issues, my phone messed up and i finally got it up and running again but now I am unable to register the sim on the network, and this happens with other sims
*#7465625# see if your network lock is off
Sent from my SGH-T959 using XDA App
I have the exact same issue. I have another phone (i9000). When I put the sim card in the other phone. it works great. Vibrant can get signal sometimes, but just cannot dial out or send messages....
Please help!
Unlock code
I downloaded the SGS unlock app a while back but had not done anything but get the code.
I powered off, installed a different sim and unlocked the phone. It was some left over sim that I knew would not give me service. After unlock and a failure to connect I powered off and put the working sim back in.
I had a little difficulty with getting 3G to come back up. Edge data and phone worked. I had to go and force a manual selection of t-mobile and then 3G popped up.
Then gmail and syncing died. I restored gmail gmail-storage and sync from backup with no luck. I'm not sure how I got it to come up but I got a password prompt and after entering it I got it back. I still had a sync error message under accounts and sync but not when I pressed on the gmail account. Rebooting got rid of that error and it's back up.
Not a clean swap at all. I'm not sure why gmail hurled.
The phone remains unlocked. If I get another sim I'll see if gmail still has a panic attack.
What should happen when you dial *#7.. on my vibrant it just says Mobile Network not available.

AT&T One was sim unlocked, but it's relocked itself?

I got an HTC One from AT&T back in June and immediately unlocked it. It worked fine with T-Mobile prepaid for a month, but the coverage sucked. I went back to AT&T prepaid.
I got a new Nexus 5 and am selling the One.
When the guy came to buy it, he popped in his T-Mobile SIM and the phone asked for a PIN on boot. What gives? Did the phone re-lock itself? AT&T customer service seemed pretty clueless on this...

It appears that his T-Mobile SIM card has the pin lock enabled, has nothing to do with your phone. It requires the SIM pin code to be enabled any time it's inserted into a phone.
Once your phone is carrier unlocked it will never re-lock itself.

I don't think that's true. I had a SGS2 i777 (AT&T) that I got AT&T to give me the unlock code. My son was using it on T-Mo prepaid. Once he put the sim in an old phone and try to set a passwd, but ended up locking the sim card. Put the sim back in the SGS2 and had the same problem. Called T-Mobile to get the PUC code. Typed the PUC code in, and the SGS2 gave a message about sim locked. Called AT&T again, and had to get the sim unlock code again.
My wife's iphone 4 had been unlocked previously, and a few month later had to call at&t again to unlock it. Don't know what caused the re-lock (she never used non-AT&T sim after the 1st unlock), but it can happen.

[Q] Help! My Atrix won't recognize any network

This is an unmodified AT&T Atrix4G, which is supposed to be unlocked, but it was a warranty replacement and I believe it was carrier locked by the first owner, before ATR&T gave it to me. Last year, AT&T's unlock code didn't unlock it, and they and Moto both claimed to be stumped when we found this out last year. The phone did recognize AT&T NVMO SIMs, but would only say "network error" when I tried a T-Mob SIM.
So this week I went back to T-Mob, thinking maybe the phone IS unlocked but needs a T-Mob APN entered to work with a T-Mob SIM. Phone was working fine, and the T-Mob guy tried to boot the phone with a T-Mob SIM card in it. The phone asked for an unlock code, we put in the one AT&T had previously generated (and confirmed, no error there) and instead the phone rejected the SIM and said "emergency mode only".
Now, it won't recognize any SIM card, not the original AT&T card (AT&T also supplied a new card in case the old one was the problem) nor the T-Mobile. All it wants to do is boot to emergency mode, or ask for an unlock code again.
I've tried the factory reset cold-boot, that didn't help either.
The phone has just gone psychotic and doesn't like ANY SIM card. Is that nuts or what?
Does anyone have any idea what I can do to get the phone working again? With AT&T or T-Mob, I don't care, I'd just like it to work as a phone again, even if that wipes all the data from it.
AT&T's store, and their local "tech center", were both dumbfounded. They claim they've never seen a phone that just won't work, won't unlock, won't take any SIM card before.

[Q] Gear S =Phone Not Allowed MM#6

Hello Everyone.
I am stumped on this issue. There doesn't seem to be any solutions for me. Here is What's happening, then I will tell you what I know..
Originally an ATT watch. SM-R750A
The IMEI is perfect. Not black listed at all. (Verified with ATT,SAMSUNG, and TMOBILE)
It is unlocked by ATT - I received the code and used it with the Tmobile Sim card inside when prompted. Success.
ATT Sim cards work perfectly,and with 4G!! When my Tmobile Sim goes in there, it only allows Emergency calls.
The APN settings are automatically populated. Verified to be correct with Tmobile. Basically, everything is fine on their end..
I am getting the run around from all 3 sources. They point the finger at each other.
Example:
Tmobile :"ATT did not unlock it completely, call them and ask for it to be fully unlocked."
ATT: "Once we gave you the code, our hands are tied. Call samsung, they may be able to complete your request.."
Samsung: "This is a service/network issue. Contact who ever your sim card has service with.."
Please help me, I have tried everything I can think of.
I researched all over the internet.. There are no working solutions anywhere!!!
I even Oden flashed the Official Firmware from ATT to Tmobile, so now my Model # is SM-R750T. I get the same errors. Att sim cards still work perfectly.
:crying:
I added photos of a menu I found on the device.. I dont know what this means..
I can draw conclusions, but I still need help..
Also, I have had the Tmobile Sim card replaced twice..
If someone could help find a solution, this will help a LOT people!
Thank You AHEAD of time.
did you flash the entire firmware package?
I only flashed official firmware from ATT to TMOBILE.. That was all. If there are further steps please let me know.
I stopped at the firmware install because I thought anything extra would have just been for customizing themes, etc..

Tmobile :"ATT did not unlock it completely, call them and ask for it to be fully unlocked."
From my understanding, there are no levels of unlock permissions. Once a device is unlocked, it's done on all levels and access.
It is unlocked by ATT - I received the code and used it with the Tmobile Sim card inside when prompted. Success.
The unlock code needs to be entered on device while connected to the ATT network...not TM's. My initial suggestion is kindly call back ATT and with the correct IMEI/ATT Sim inserted, enter unlock code again. You may need to flash back to xxxA first.
My thought here is the phone isn't unlocked according to ATT's server's Device ID data...when you reestablished connection with ATT, it locked the device again.
[Q]
You said that you got the unlock code from ATT, with TM Sim inserted, and it was a success....
Why did you go back to the ATT Sim again if you had it working?

The unlock code worked. I was not prompted to enter another unlock code. I received success notification. I immediately got the error code that you see in the pictures. Could not dial out. So i went to ATT store for some hands on troubleshooting. But I will try to use the sim card idea you mentioned. I will come back with an update.

The same here. I'm from Vietnam. My boss from USA visited Vietnam office and gifted me a T-mobile Gear S with the unlock code from T-mobile. Before unlocking the network, i upgrade it with the latest firmware from T-mobile (R750TUVU1A07). I then inserted a VN carrier SIM and did follow T-mobile guide as below:
1.Insert a Non-T-Mobile SIM & turn the Gear S ON.
2.The Gear S will automatically prompt you to enter the unlock code.
3.Tap in the unlock code provided by T-Mobile and click OK.
Note: The device should display code accepted

After i receive the successful message, i still cant make call or send message. It keep saying that "Mobile network is not available". I tried with 3 nano sim cards from 3 biggest carriers in VN but there is no luck. (These sim cards work well on the iPhone 5).
BTW, the GPS also didn't work, even before or after unlocking with the code. It keep saying "GPS signal too weak. Please connect the Gear to mobile device via Bluetooth" (or something like that).

You most likely will not be able to use a North American S outside the US. It has nothing to do with the software...the frequency bands are different and hardcoded. You may want to check and see what bands are used by the providers in VN for cellular ie: 2G, 3G, etc and compare those to what US/Sprint uses.
I have the same issues with the GPS. Even when I'm outside, in an open area I can't even get the weather app to update. Not sure how many people have this issue, but it doesn't seem to be a topic of discussion on XDA.

This is from "CELLUNLOCKER" where I got my unlock code...before it was free...lol....... When I click on the t mobile for network....I get "registered to networkk" popup with my ATT GS. When I call a number I get the tmobile cust servc help line...... since I am not a tmobile cust.
I cannot remember which method I used....but I can go with att or tmobile sims with no issues. Right now I have H20 as my carrier, on the ATT network...but at least I know I can go to the Tmobile network or carriers anytime
How to enter unlock codes on all Samsung models
Different phones have different Unlock Code Input Instructions, Try the following Instructions in order:
Note: Non Accepted Simcard is any simcard not from the original provider
Method #1 Insert a Non accepted simcard in your phone and power on. Once finished loading your phone will ask you to enter a code, enter the Unlock Code
OR
Method #2 (NOT applicable for newer Samsung phones, ie. Galaxy S3, S4, S5, Note 2, Note 3, etc)
Go to the dial screen on your phone as if you are going to make a call and press: #7465625*638*UNLOCKCODE# (8 digit unlock code)
OR
Method #3 (NOT applicable for newer Samsung phones, ie. Galaxy S3, S4, S5, Note 2, Note 3, etc)
Go to the dial screen on your phone as if you are going to make a call and press: #0111*UNLOCKCODE# (8 digit unlock code)
OR
Method #4 (NOT applicable for newer Samsung phones, ie. Galaxy S3, S4, S5, Note 2, Note 3, etc)
Go to the dial screen on your phone as if you are going to make a call and press #7465625*638*# Once prompted for code, enter the 8 digit Unlock Code.
When this method is used for newer Samsung phones, it will say "unsuccessful" regardless of the phone being unlocked or not.
Phone Not Allowed MM#6 Tmobile- A clue to problem?
I also have the same problem...it is frustrating.
i have an unlocked AT&T Gear S ( unlocked thru one of the unlock ebay sites. it seemed to go well, and worked)
i setup account with Tmobile, and it worked, i have had it about 2 months, all OK, until..
i took out SIM to test with my unlocked IPHONE 6+, (i have been thinking of switching all my phones to Tmobile) it also worked OK,
Then i swicthed it back into the Gear S, and the trouble started (unless it was a conincidence),
'Phone not allowed MM#6', it tried everything.
1. reset Gear
2.rebooted thru the gear boot menu
-i called Tmobile, they did not have answer,m they asked me to try a new SIM, which i did online and updated account with new SIM,
same problem.
3.Tmo said maybe not complety unlocked to contact AT&T but i doubted this,
4. I tried a freinds SIM from his Iphone 6+ (on Tmo) it worked great in my Gear Sm and my 'unlocked Ipphone 6'
5. i tried my Gear S SIM in my Iphone, message poped up 'Phone not allowed' (this time no MM#6)
6. called Tmo again (maybe 3rd time) suggested another new SIM card, they everything on there end looks fine, they checked imei, sim card etc, all OK.
i told them from what i have read the forums mentioned a network problem, not a phone problem.
They connected with Samsung, they said they can try reflashing the Gear S, if i send it in to them,
7. i called Tmo again, and i spoke one rep who , GAVE ME A CLUE TO PROBLEM.. he found a note concerning the Gear S,
it said if the user puts the Gear S SIM cards (wiith the 'wearable plan') into another phone, it will block the account until the user reinstalls SIM into Gear S.
8. if this the problem, iit is not reseting itself when SIM is back in Gear S.
9. Not sure what to do next.
the last Tmo rep told to go into Tmo store, and they will try another new SIM, and ask them to try new SIM and my in anoother Gear S, but it seems many tmo stores dont have Gear S on hand, only display it am checking.
10. One idea may be to close the whole account and open new account for the Gear S.
did anybody have luck with this problem?

I have the factory unlocked international version, SM-R750W, and several people here said it wouldn't work. It worked perfectly for a day, then nothing. New SIM, it worked perfectly again for maybe 5 minutes.

Still no luck, but maybe a couple more clues;
1. As the tech support advised, I went to a Tmo store, and they swapped the nano sim , no help.
2. I put in a sim from my friends tmo iPhone. It seemed great.
3. I called tech support back, they escalated problem to the engineering dept,
Said it may take 2 days to hear back...... So far no luck, please let me know if you have better results.
(I did check the plan online and with support to be sure it was correct.- the wearable / watch plan)
I feel it has something to do with there network 'rejecting' my imeo, but support checked that several times, as said it is correct.

They escalated my situation as soon as I called them on Tuesday and told me 3 days. Nothing yet.
Have you used the Tmobile IMEI check? http://www.t-mobile.com/verifyIMEI.aspx
I just tried it and it doesn't recognize my IMEI....But if that was going to be a problem, shouldn't that have meant it would never work? I can't think of any reason it would work for a day before they shut it off.
I had same result "did not recognize" with there Imei checker, further, the support reps checked several times and said it is Ok, My gear s is an unlocked AT&T, it did work for the first 2 months (until I removed sim to test in my iPhone ( I was considering switching all my phones to Tmo) Maybe coincidence? + But with a friends sim (from his iPhone ) it worked immediately , it even populated the Apn etc settings, but i did not leave on more than 1-2 minutes to test.
When I put my sim back in, it does not register, it does even show phone number, says:
"Phone not allowed MM#6" and emergency calls only.
I had this same issue come up. The way I solved it was to close out the account for my phone number tied to the watch wearable plan. And then I created a new phone account for the wearable plan with a new number. And got a new sim card from T-Mobile at the time of creating the new wearable plan / number. It seems that the phone number that was previously tied to my galaxy gear s was not blacklisted, but the services were limited on it because I had taken the sim card out of the gear s watch and put it into a cell phone to test if there was service on it. So that flagged the wearable phone number account like I was trying to steal data/phone service from T-Mobile by using the only $15 / month plan on an actual phone. Like said above, the services are supposed to be restored once you put the sim back into the watch, but there is a bug with T-Mobile's service in doing so. So in the end, I closed out the "flagged" account, opened a new account and will never put the sim card into a phone again in the future.
same the issue

The same here. I'm from Vietnam. My boss from USA visited Vietnam office and gifted me a T-mobile Gear S with the unlock code from T-mobile. Before unlocking the network, i upgrade it with the latest firmware from T-mobile (R750TUVU1A07). I then inserted a VN carrier SIM and did follow T-mobile guide as below:
After i receive the successful message, i still cant make call or send message. It keep saying that "Mobile network is not available". I tried with 3 nano sim cards from 3 biggest carriers in VN but there is no luck. (These sim cards work well on the iPhone 5).
BTW, the GPS also didn't work, even before or after unlocking with the code. It keep saying "GPS signal too weak. Please connect the Gear to mobile device via Bluetooth" (or something like that).

So, right now, the Gear S is just a digital watch to me, ha ha.
The error is specifically a sim/network error unfortunately and more importantly this;
9 out of 10 times MM6 error means the phone has been reported lost/stolen and the IMEI has been network blocked.
Here are a few options that could be causing most of the issues I have read;
At&t is NOT open and a fan of allowing devices outside their network. Therefore its possible your device is literally reported as lost/and or locked to at&t and they dont want it on T-Mobile. And your best bet is to raise hell threating an investigation by the FCC.
At&t re-locked your device when att sim is put in.

lg k8+ x210 ulm unlocked carrier sim issues

I have an lg k8+ model x210ulm that i want to use with cricket. The phone is fully unlocked and will accept any sim from any carrier but has an odd behaviour that wont let me use my own sim.
I bought a feesh sim from cricket and when i put it in and set it up it will register with crickets apn and mobile network settibg. I get data and it shows up in the about network as connected and working. It shows cricket carrier in notificstion and i can get texts and even voice mail. But ........
I cannot use the dialer. Upon connection there is no error toast or anything it just imnedistely hangs up.
I can use my wifes my sons or my friends sims in the phone and after a reboot works perfectly. But when i put mine in it stops.
Also my sim works fine in any other unlocked device or cricket device.
Any clue as to wth is going on
Ok so after talking to lg and really that was frustrating. Why because the rep told me it the phone was carrier locked to us cellular which i knew it wasnt because its advertised as being unlocked and well us cellular put up an advert a few years ago stating that all thier phones are unlocked.
So after that i went ahead and talked to a rep at us cellular who assured me it was unlocked and checked the imei for me and sent me link to the advert about thier phones being unlocked.
Back to lg and got another rep this time who knew a lil about something but not much. Could not tell me any thing though.
Now back to cricket where we tested my girlfriends sim in my phone to which it worked and mine in her phone to which it worked. We put the sims in my aristo 2 and fortune 2 and both sims worked. But when i put my sim back in my my k8+(2018) once again every thing works fine but you cannot make or recieve phone calls.
We also tested the voice mail app and and thier what qualifies as a carrier app and it registers. The sim registers in about phone shows service and is connected. Shows the phone number every thing works.
Just not the phone Dialer app
So is there any one out there at all that has had an issue like this before. Any one that can help me figure out what the problem is. This is so crazy that my sim wont work and every one elses will.
Could it be something i did using dialer codes? Any cLues at akl
So here we are months later and im still having sim issues with my k8+ ulm. I ended up buying a brand new device and i tried my provisioned sim card with it not working but literally every other sim card works fine.
I have switched from cricket to assist wireless now who is run or what ever by sprint and i can get the sim card to work for a couple days before switching it to another phone but the main issue is that i get a error popup stating that the sim card has locked and that i need to power cycle and call customer service.
But i made a ton of changes by adding all the system apps from sprint including sprinthiddenmenu and any other apk that was on the tribute dynasty they came from. I also went through the file system and made any prop changes or any thing else that was needed to enable sprint.
At this point id flash a sprint modem but i cant find a cv1 device provisioned under sprint
