Using an unlocked phone on the original carrier?
Hey guys
Quick question on unlocked devices. I have a T Mobile branded phone which was unlocked via MEP code. When I entered my AT&T sim card in the phone it asked to enter the unlock code.
My question is, what if I entered a T Mobile sim card in the phone, will it still prompt me to enter the unlock code or will it work like normal since it's a T Mobile branded phone? I shouldn't need the unlock code in this case correct?
Just checking for potential compatibility issues.
Thank you all!
