No acces at all with prepaid SIM.
i am for 2 weeks at holiday in the sates enjoying your beatiful country. Comin from germany I decided to buy an AT&T SIM 5G 5GB for 30 days. But there no access, no data, no calling. The SIM is recognized as unknown but the phone number is correctly shown.
Here a few Info of my phone:
Typ: Galaxy A53 5G
Model number: SM-A536B/DS
IMEI Slot1: (Edited as per community guidelines)
The error message I get ist >> nor registered to the network <<
I deactivated the automatic mode to search a network provider an choosed AT&T, tried different APN, did restarts, but nothing worked.
Any ideas, what to do? Help would be very appreciated.
Thanks in advance and best regard
