Tmobile sim unlock + bootloader unlock to switch to Global. MSM tool will it relock the sim? - OnePlus 8T Questions & Answers

I unlocked my tmobile one plus 8t and bootloader unlock to switch to Global for the dual sim. But now i want to switch back to tmobile by using the msm tool to restore.
Will it relock sim on phone or will my phone still be unlocked after msm without doing anything?

SIM lock and unlock status are independent of the OS, so flashing between Global, T-Mobile, Chinese, India etc, will not alter the SIM lock/unlock state.

Have you had the phone activated with an active SIM inside of it for 40+ days?

Yes, that's what T-Mobile states you need to fulfill in order unlock your device.
If you're not the original owner, they WILL NOT unlock it.
you need to be on t-mobile firmware
Flash back to the T-Mobile firmware with MSM Download Tool, then unlock with the app. Then flash to the international firmware again with MSM Download tool then you'll be able to fastboot oem unlock without issues.

Chinese Redmi 6 not accepting SIM after changing from Global ROM

I had a chinese redmi 6 that had an unlocked bootloader and global ROM and it was using a Giffgaff SIM. Bootloader got locked and it bricked. Finally got it back on its feet again with a chinese ROM and want to unlock bootloader which requires a working sim. However the giffgaff SIM will no longer work, the phone recognises it and my phone number and all the network settings but wont use it.
Do i need a chinese sim?
Thanks!

T-Mobile Carrier Sim Unlock

I have a T-Mobile OP 8T that I converted a while back to global in order to unlock bootloader. Recently I paid the full balance on the phone and from reading online it can be unlocked with the T-Mobile Unlock app. I downloaded the T-Mobile unlock app, but its not working on the Global rom. Anyone know how to sim unlock a paid T-Mobile phone or do I need to call to do that?
Try this?
OnePlus: Settings > Wi-Fi & internet > SIM & network, then choose Advanced or Network Unlock

Yes, you needed to unlock SIM with T-Mobile's app before you converted to global.
You'll need to MSM back to OOS11 again. After unlocking is successful you are free to upgrade to OOS13 or flash a custom ROM
