What Roms work with Sim unlock?

I have a G2x rooted and running Weapon 2.4 and have entered the sim unlock code in a previous rom ( stock rooted ). I want to use the phone with a gophone prepaid sim when I go to Mexico. What roms work with the sim unlock? The phone now does not read the sim card.
Thanks in Advance

CM7 will definitely work, not so sure about the stock based roms though

Any rom should work once the phone is unlocked. If the rom cannot read the sim card then I would try another rom. Or your sim card took a dump.

any rom will work
th eunlock is hardware unlock not a software
i t unlocks the hardware to support any sim - i use an unlocked phone in india
once it unlocks it is unlocked for ever
any sim any network any rom u can try it will work fine

Use a stock ROM

First of all, you have to obtain unlocked code. You can obtain from T-Mobile if you passed 3 months after you requested last unlocked code, and the phone passed 14 days (30 days in CA) trial. It is recommended to request it through online chat to ensure it's 100% correct (you can obtain your IMEI by key in *#06# from dial. Make sure you triple-check it).
After you obtained your unlocked code, go to dialer (you don't have to have foreign SIM but it is recommended to test) and input
2945#*999#
(this method works with ANY LG GSM Android phone because #*xxx# is actually your phone model. For example, Optimus T is P509 then #*509# and G2x is P999 so #*999#)
Enter unlock code correctly. Once you verified everything is correct, you can press the button below, and the phone will reboot, then the phone is unlocked.

When I swapped SIM in CM7 based ROM, the unlock screen kept crashing and was scared because thought a CRASH=WRONG CODE Entered.
I Flashed to EB 2.3.3 Stock and it worked. Phone rebooted after the code was entered. Message said "Network Unlock Failed"
I had an extra SIM to test and verified it did work. Again I did it without swapping SIM but better to do it on a STOCK cooked ROM.

Oh, and also, ANY ROM will work with the SIM you enter
As long as the APN gets properly you are fine.
I unlocked my phone to try Straight Talk. APN had to be modified to make MMS/DATA work. Again, this was a special case cause I'm not suppose to use ST SIM on a non-ST phone.

T-Mobile SIM LOCKED After TWRP Restore. Help!

Hi guys need some help! :'(
I bought a N920-T from shop which was Unlocked and Working for other carriers on Kit Kat rom.
I then installed stock Marshmallow using Odin/Rooted and TWRPD it. And it was fully working with my international SIM. I made a backup of my fully working unlocked Marshmallow with all the items checked (EFS and MODEM too).
Today, somehow my rom got stuck and crashed and I decided to Restore it using backup which I made. Restore got through and everything was back EXCEPT I see "Network Lock:" screen on first time boot up after restoring it.
"The device can be remotely unlocked if eligible. Please use "Device Unlock" application to unlock the device."
Please help! What should I do? Should I launch the T mobile device unlock application and continue it with wifi and see what happens?. Or what?. My device was unlocked and fully working on Kit Kat and Marshmallow too. It means it was officially unlocked right?. PLEASE GUIDE.

It would not hurt anything or make things worst for you if you tried the Tmobile Device Unlock,
it will either network unlock your phone or it won't.
I used Device Unlock on my Tmobile Note 4 and my Tmobile S6 Edge+ and in both cases it
worked fine and unlocked my phones.
Good luck,
Have a great day!

First off the phone shipped with Lollipop not kit Kat. Second a true Sim carrier unlock is permanent and can't be undone as far as I know.
I do remember when you use the device unlock app their is an option to temporarily unlock, I wonder if that's what you had?

Unlocking the carrier lock is permanent
No amount of modding would change it
See if your phone is eligible to unlock: Mobile Wireless Device Unlocking.
From that Application list, tap Device Unlock.
Tap Continue.
Wait while the device connects to the server.
Choose the desired device unlock type:
Permanent Unlock: Permanently unlocks the device.
Temporary Unlock: Temporarily unlocks device for 30 days.
Note: Temporary unlocks must be performed with a mobile data connection. Wi-Fi will not work.
Wait while the device requests the unlock.
If successful, restart the device to apply the settings

I can't even use smart switch to go back to stock

The T-Mobile app didn't work. Permanent and Temporary Unlock said my device is "not eligible". I am confused, when I bought the phone it was working with other Sim and was on Lollipop/Rooted and then I installed Marshmallow T-Mobile Stock Rom via Odin/Rooted and it was still Unlocked then back up which I created was with EFS and MODEM checked in TWRP of Marshmallow. I think the EFS and MODEM option in backup creation and restoring it messed my phone up. But I am still wondering how was it unlocked?. T-Mobile says my mobile is ineligible, maybe shop owner used Z3X Box Samsung Tool Pro or something?
UPDATE:
I decided to use unlock services online. The one I used was unlockbase they have a software that unlocks the phone on-the-go and it requires internet connection. I got my phone unlocked and international SIM working. The question is that if I backup my EFS and MODEM now using TWRP and later restore it will it break the UNLOCK?.They guarantee that their unlock is permanent and modding won't do anything.
Because the unlock they do is of course by altering the EFS/FILES and in that case backing up EFS and MODEM is a safe way to UNLOCK my phone again in future if it somehow gets LOCK again, right?.
For Developers: I have my before/after EFS files backups. Before unlock and after unlock, if some developer wants it for research purposes, I can send it to you for the sake of development.

ask the gentleman to unlock it on xda he's awesome! Never restore it'll cause you to loose unlock under all cercumstances I've learned not a big deal

UPDATE:
I have Saved my UNLOCKED EFS and Modem Files, and upon restoring those using TWRP my phone gets unlocked, tried purposely after locking my device and it works, you just gotta save them EFS Files (unlocking services like via box or online tools edit these files in order to unlock) , they are the real deal lol. Made Several copies of my Unlocked EFS/Modem Files xD

Carrier Unlock Samsung J7 (6.0.1)

Hello. I bought an Unlock code for my J7 that is locked to T-Mobile UK.
The problem is that when I insert any other carrier Sim card, the phone don't ask me for the code. It only shows some message saying that the phone can be unlocked remotely and the option I have is "OK". Even when i dial *7465625*638*# nothing happens.
Does anyone knows what should I do?

I used the T-Mobile unlock app I have been trying to unlock it for a ninth. Just happen to hit it tonight and it said device permanently unlocked and I been trying for a month

SM-G930T shows up as SM-G930U in settings.

thought i bought a unlocked sm-g930u but looks like I got the T-mobile varient. The model number is SM-G930T on the back glass and that's what shows up when pulling imei but checking in the settings it shows as the SM-G930U. Worked fine for about a month on the straight talk AT&T network and then I got a notification saying "unlock expired, restart required" and then I got the invalid sim notification. Phone is now locked to t-mobile. There's absolutely no T-Mobile bloatware...not even a T-Mobile splash screen. It doesn't have root access...what's going on here? I can't even get a unlock website to take my money lol

Sounds like someone requested a temporary unlock through T-Mobile, then flashed a U variant ROM...then the temporary unlock expired. You got screwed basically.

Download the official T-Mobile unlock app from the Play Store and try to permanently unlock it...if that doesn't work...try flashing the official T-Mobile firmware in Odin, then try the unlock app...if that doesn't work, then someone sold you a phone that's still on a payment plan through T-Mobile.

ATT APN for official OTA? please help

I have a carrier unlocked Note 8. I am currently running stock AT&T firmware. I am trying to figure out how to get the OTA updates on my note. If I need to add a different apn. Does anyone know which one if is? Or is there something else I need to do?

Are you in AT&T network with AT&T sim card (either postpaid or prepaid)?
You can only get OTA from AT&T network server. I know it sucks.
You can borrow AT&T sim card from friends for a few hours if you're using other carrier's sim card. Or flash XAA firmware (unlocked and unbranded).

Yes I am on AT&T network and with AT&T sim card. But I still don't receive the OTA

If you can make a call or use AT&T cellular data,
put this in your phone app: *#8736364#
Then go to Field Test mode.
Change "Device Initiated date" to one or a few minute ahead. wait until you see "SET" then press Home.
Wait until you see software update to kick it.
Try several times if it doesn't work at first.
Still doesn't work? then put your sim card in different phone and turn on for 10min then put it back in your note 8.
Try again.
For your info, my note 8 is unlocked too. And in AT&T network.

No I have not received the updates. I did them manually through odin.
So I keep doing the same thing when window Pops up by themselves.

So.... did you try my method?
If you're AT&T customer, why don't you drop by AT&T corporate store for assistance?
I am not AT&T customer, that's reason why I borrowed sim card.

Yes trying but don't get prompt to update. AT&T wont help if it's a carrier unlocked phone. Did you have to change your apn at all?

borijess, if I am correct, I think you mean you have an unlocked Note 8 directly from Samsung, right? You then odin AT&T firmware so you have a SM-N950U phone now. If that is true, you will not get OTA update from AT&T. This has been discussed before. AT&T will not put your IMEI on their white list. Only phones bought directly from AT&T will have their IMEI on the white list and those are the phones that will get OTA update. Many people have tried to call AT&T to add their IMEI on the white list but to no avail. We are stuck with odin every update, sorry.

Yes unlocked from Samsung.

Unfortunately, you will not get OTA update. I have tried multiple phone calls to AT&T to put my IMEI on their white list but unsuccessful. AT&T are on that power trip to try to force customers to buy from them. My contract is up soon and will definitely switch. Anyway, I have been doing odin since I got the phone to update.

I could pull AT&T OTA update on Red Pocket (GSMA plan). Red Pocket has same MNC MCC as AT&T.
