Try changing mobile network option 4g to 3g, put in plane mode for a moment, Restart the phone and remove the back cover, finaly flash stock

Oneplus 7t T-Mobile Carrier Lock

Hey Everyone!
I was fooled into buying a Oneplus 7T, which I was told, was SIM unlocked.
Once I got the phone and inserted my SIM, a message popped up saying it is network locked to T-Mobile.
I tried using the T-Mobile Device Unlock app but it did not work. (Some kind of error message)
Is there any way to unlock the phone since all i have the imei number of the phone only
Also sorry about this being my first post
Hopefully there is a way to unlock the carrier
Unfortunately you can't bypass this, so to unlock your device you have to request it from T-Mobile if you meet the requirements.
OR You can follow this thread and your new best friend will unlock it for you.
On a side note: Learn how to search, that way you save yours and others time.
Or convert to Global via hacked msmtool and everything unlocked

In a phone that is SIM-locked, the firmware needs to find a specific pattern in a portion of the SIM card's identification number (IMSI). This portion of the IMSI identifies the country in which the SIM card was issued and the service provider which sold the sim card.
If these do not match the specific country and/or service provider to which the phone is locked, then the firmware will refuse to use the SIM card.
If the firmware includes a SIM-lock, generally the ROM is powerless to do anything about it. And to unlock it you need to follow a specific procedure that network operator or the phone manufacturer offers.
That's why the phone will remain SIM-unlocked even after you switch to a different ROM.
From the above you get that the lock exists in the firmware, not in the ROM.
Maybe my phone was not locked at TMobile central and only at rom level. I'm just happy I can use non TMobile provider for cheaper cost (Mint mobile is $20/mo for 10gb data and unlimited talk/text). I couldn't before converting as it rejected non TMobile sim, but could afterwards
Please any help on how to sim unlock my Tmobile oneplus 7t? Third party unlocks are too expensive for me. Unless anyone knows a cheaper unlock service below $30?

Mint uses T-Mobile towers. So a T-Mobile device doesn't need to be SIM unlocked, in order to use Mint.
The same goes for Metro or any other carrier that uses T-Mobile towers
Not possible unlock

Might be a silly question, but have you tried contacting T-Mobile?

Question E-Sim after upgrade / software change

Hi,
is here someone with experiences about E-SIM? when ive got pixel 5 with 2 active SIMs, one plastic, second one E-SIM and tried custom ROM, E-SIM was blocked, not active when booted those custom ROM, when i was returning back to previous stock ROM the E-SIM was still unactive and it was needed replacement for a new plastic sim/reactivation.
My question is, will this happend when i want to flash stock update to latest stock ROM via android flasher web or adb commands?
Every activation to E-SIM or back to plastic is from our operator 10e
Thank you.
No idea but I use e-sim and did flash a stock OTA update as well as custom kernel (and also factory resets and root) without a problem.
eSIM is persistent if I'm not mistaken. when I flashed CalyxOS, my eSIM was still active.
did you try flashing the full images (on both slots) ? if not try the official Pixel Repair site:
Google Pixel - Update and Software Repair

Question LE 2127 no signal

Need help here! I forgot to backup my oneplus 9 pro LE2127 when I tried to root my phone using TWRP,and I installed TWRP in my phone's boot partition which wiped out all data in that partition. I used TWRP side loaded Global ROM to recover my phone but the phone doesn't have any signal with sim card in. Used MSM tool backe to T-Mobile 11.2.5.5 and still same problem, sim card can be read but no signal. Flashed T-Mobile modem but modem b failed, it says no such partition.
Bought this phone from third party. Any suggestion is appreciated.

Tried network reset
Tried fix the APN.
Nothing helps

Question Volte suddenly stopped working

Hello, Volte used to work well on my op9 pro recently updated to A12, I tied switching my sim card from sim 1 to sim 2 as I read some users were able to connect to 5g that way, well, it didn't work and when I switched my sim back, volte stopped working, tried restarting the phone a couple of times, no luck. Any ideas ?
Also, even before switching to A11 5g never worked and still doesn't work on my 9Pro in the UAE, tried all possible solutions and it still doesn't work, any possible solutions?
Can you try to reset your APNs and/or the whole networking? (Beware: by resetting the network you'll loose your saved WiFi configurations.)

I just tried that, didn't work unfortunately, no volte or 5g, I only get 4g+ and my sim supports 5g on other devices :/ I can live with 4g, but I need volte to work

I was getting the same issue, but flashing a different variant of your current c.44 should do the trick.
Ex: I have a LE2127 (TMO), I converted with a11 to use LE2123(EU) software updates. When android 12 hit my phone wouldn't give me data on the 2123 update, so I had to download the LE2125(global/NA) update and flash using the the system update app that was so generously given in the following post:
Post in thread '[TMO] 9 PRO MODEM RETENTION' https://forum.xda-developers.com/t/tmo-9-pro-modem-retention.4292445/post-86328243
I don't know what software or model your phone is now, so I am NOT suggesting you switch if you are not already on 2123 or 2125. Those two are interchangeable without problem so it should be fine
