OnePlus 6T was officially launched in the U.S. previous year with the T-Mobile branded OnePlus 6T. All the features of the device were the same as to that of the international variant, but with a few minor difference in the sim card tray. The T-Mobile OnePlus 6T has a single SIM nano-card slot.

How this worked was the customers who bought the T-Mobile version of the OnePlus 6T, needed to pay-off the price of the device completely and get the SIM-unlocked before they could go ahead to unlock the bootloader of the device.
Moreover, this process took at least about 40 days for completion. However, there is some good news for the T-Mobile OnePlus 7 Pro users as there is a workaround for unlocking the bootloader and skipping that 40 days of time for unlocking the bootloader following the official procedure. Thanks to XDA Member, Daniel Marchena, discovered this method of unlocking the bootloader, even if you do not qualify for the official unlocking procedure.
