will i be able to use a T-Mobile phone on AT&T network if i install AT&T firmware?
i have a T-Mobile galaxy edge and want to use it on AT&T network and i was just wondering if i change the firmware will i be able to then use it on the AT&T mobile network?? or if anyone knows how i can do this please let me know how, from what i've learned the lock is due to a certain permission needed from the IMEI, i was also wondering if it can work by changing the IMEI??

Hello, and welcome to XDA!
In short, no and no. A SIM lock is due to something different. A firmware change from one carrier to another (in my experience) will not only not affect the SIM lock, but it can be disastrous for the phone. Changing the IMEI also has it's consequences.
I am connecting you to the forum your device experts can be found (T-Mo Galaxy Edge Q&A):
> T-Mobile Samsung Galaxy S6 Edge > T-Mobile Galaxy S6 Edge Q&A, Help & Troubleshooting
The experts will likely have some suggestions on how to SIM unlock.
Please note, to respond to replies, you will need to register for an XDA account.
Hope this helps, and good luck!
Hello everyone,
Yes, I'm a noob here but online research, etc. tells me that XDA is the place for me. I am a IT tech, just not a programmer nor have I done a lot with flashing phones, etc.
based on some basic searching my issues seems to be common.
I am a T-Mobile user and I now have a new AT&T Branded Galaxy S9 SM-G960U. I paid a third party to provide me with a Samsung unlock code. I unlocked the phone last night, had T-Mobile update my account with my new Nano Sim, etc.
All is working except I can not enable WiFi Calling and of course there are some advanced text messaging features that I can not enable, i.e. sent receipts, etc. I tested the phone with a active AT&T sim and the features work fine.
Does anyone have a work around for getting WiFi calling and text features to work using the T-Mobile Sim?
Do I need to some how flash a T-Mobile ROM to the phone?
Any help and guidance would be greatly appreciated
it will never work because is att brand. you needed to get international model.
I'm not so sure.......... I have the SM-960u1 and have flashed various AT&T FW to it at least 50 times and cannot get any IMS features to work. I get get the ATT bloatware, software,splash screen. But no VoLTE, WiFi Calling etc. I am tired of flashing. Back to Stock U1 for me.
AT&T is the same. They keep promising wifi calling for unlocked phones but I can't get it and neither can 2 others I know with unlocked phones.
This sounds normal. I have an AT&T branded Galaxy S6, which has wifi calling, but I'm using a MintMobile (T-Mobile) SIM. Wifi Calling is grayed out. There's probably some sort of check in the software that only enables the wifi calling if you are using an AT&T sim.
Yes, you have to flash the T-Mobile firmware with the latest modded Odin, or the unlocked U1 variant firmware (for which TMO's RCS messaging and video calling won't work-with U1 firmware, I mean). If you flash the TMO firmware, it's for all intents and purposes turning the phone into aTMO phone, with bootscreen, bloat and all.

You will need to flash to the U1 Firmware then Flash the T-Mobile firmware. AT&T's Wifi Calling is proprietary and thus their phones software won't work with other Carrier's Wifi Calling.
Has anyone tried to add the mobile data toggle on the Note 10 plus? I know there is a way to do it on the S10 plus and other models. Not sure if there is a way to do it on the Note 10 plus yet.
just so everyone know. i dont know about carrier branded note10+
but unlocked note10+ do have mobile data toggle.

Yeah mine is unlocked but I flashed it to the ATT firmware so I can use Wifi calling.
Wondering if anyone can verify if Verizon HD and WiFi calling work on the unlocked A50? They actually both work fine on Sprint without any issue, surprisingly.
As an FYI, I visited a couple of Verizon corporate stores and found the following... The unlocked A50 and the Verizon branded A50 will both do WiFi calling, but neither has VoLTE. Sprint does both - there's a VoLTE indicator in the status bar and a switch in the phone Settings. Verizon has no switch for VoLTE.
Purchased a Redmi Note 8T phone to replace my mother's aging LG feature phone, specifically due to TMobile USA dropping support for phones without VoLTE in January 2021. Followed the steps to disable the carrier check *#*#86583#*#* and confirmed that VoLTE option shows enabled on *#*#4636#*#* menu. Also confirmed I'm getting LTE signal and data. In the SIM settings it shows VoLTE enabled but no icon next to signal indicator and doesn't say HD when making calls. IMS status says Not Registered. Any suggestions? Is this because the phone has been on the TMobile network for only a couple hours? Or because TMobile still thinks she's using the LG feature phone which definitely wasn't VoLTE capable?

After much testing and process of elimination we have basically determined that either it's not possible on the US T-Mobile network, or that getting it to work is far beyond my technical capabilities.
