Locked iPhone 12 purchased through a third party seller in Germany
My IPhone 12, purchased through a third party seller in Germany, is locked. I did everything according to the instructions, sent the IMEI and received the request number, then inserted a new card into the device, but again I got a message that device is owned by ATT and remote management is required. I would like to ask for more help.
