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!
Hello,
I got a new xiaomi poco and i'd like to unlock the bootloader. However a sim card is needed. I do have an old, deactivated sim card lying around. The phone does detect it but it doesn't recieve any signal and i can enter the xiaomi login menu (impossible without SIM). Has anyone tried unlocking the bootloader with such a card? Was it successful?
Thanks in advance
Hello!
I have a Huawei P20 bought from Orange, the problem is that orange changes the phone software to work only with one sim card even this model is dual sim, so is there anyway to get dual sim, I have seen older methods that require unlocked bootloader, but Huawei doesn't allow unlocking it now.
Thank you!

Is your device completely paid in full
-- As long as your device is unlocked (60 days after initial purchase from Verizon) then it will work with any SIM
-- Refer to porting out your mobile number to another carrier
-- Power off device, remove SIM card, wait a few minutes, reinsert SIM card and try again
The Verizon modem only works on the Verizon ROM, unfortunately. Unless you want to flash a custom ROM, you have to stick with OxygenOS to keep your cellular data if you have an IN2019.
