1. First of all unlocked bootloader.
2. Flash any android 10 (T-Mobile) MSM rom.( I have tired10.5.9 )
3.Unlock bootloader again.
4.Flash any android 10 (GLOBAL) Fastboot rom.i have tired (10.5.9)
5.Now upgrade your device to lastest android 11 through updater or manually.
6. Now you have dual sim compatibility.
some time it takes time for dual sim working,wait a week or two weeks if your phone doesn't pick second sim signal

Converted my oneplys 8 t-mobile to global and swapped to dual sim tray. OxygenOS recognizes two sims and the timezone got updated when i traveled to the other sim.
However, i can't call or data to work. Eventually, I had to physically swap sim2 to sim1 to get it to work. Oneplus 6t conversion does not suffer from this pitfall.

1I was curious as a colleuge of mine recently purchased the OP8 5G from T-Mobile rather than directly from OnePlus. The sim tray only supports one SIM, and I am assuming that as it has been done historically on prior OP devices, the T-Mobile OP software only supports one sim card. I am unsure as to whether the T-Mobile variant has hardware to support two sims or not, but I think it may only a software issue. Would rooting and flashing to get onto the Global firmware enable dual-sim support for a OP8 5G T-Mobile variant?
Thank you,1Yes I have successfully convert my T-Mobile OnePlus 8 to global ROM and now I have dual sim compatibility.1
1. First of all unlock bootloader and u also have permanent sim unlock from t-mobile.
2.After unlocking your phone will restart, setup your oneplus 8 and enable developer mode and in developer mode enable "usb debugging" .
Note: You must have working adb/fastboot drivers.
3. now restart your phone to bootloader.
4. Download any android 10 fastboot Rom from xda developer.
"I have tested this : https://sourceforge.net/projects/fastbootroms/files/OnePlus 8/10.5.9-EUROPE-OnePlus8Oxygen_15.E.18_OTA_018_all_2007160043_913306-FASTBOOT.zip/download
4.1. For flashing this rom your phone has to be in fastboot mode.
5. After downloading extract the rom and open extracted folder and double click "flah_all.bat
5.1.connect your phone to computer in fastboot mode and enter "Y"
wait for 5 to 7 minutes, in this process your oneplus will restart to recovery mode but never unplug the cable or use your phone during installation.
Note: i have tested dual sim with dual sim tray.1
Brother after flashing eu10.5.9 just update your OnePlus to latest 11.0.8.8 (because dual sim compatibility is only available in android 11/oxygen 11) and then lock the bootloader after locking your phone will rest and u will see dual sim compatibility after setup.
Maybe looks wired but works for me1
Hi man, can you make calls on both sims?, im on Global 11.0.8.8 and i can see both sims but just the sim1 is working the sim2 doesn't work
