Need some help please.
I have tried both a foreign SIM as well as an AT&T SIM. I get the message "SIM from an unknown source". What is the next step? In settings, wireless networks, mobile networks, I see only 2 options: 1. CDMA/LTE 2. CDMA only.
If I go into Network app (from the market) and select GSM Auto, I get new options to select an operator in settings. However, after searching for an operator it never finds a network. This is with both the At&t SIM card as well as a german SIM card.
