...and it went wrong. At first i bootet my Pre+ with my old SIM and did a full erase. Then i booted the old Pre+ with my gitls SIM and it boots and boots and boots - and then it starts the language configuration. After I choosed "german" it again takes inuts for the next step - and then it comes up with the configuration screen, has no telephone number setted up and also shows me "no sim - sos only". If there was no SIM inserted, I couldn't configure even the language, so what is the problem here? It is a german O2 pre+, which comes unlocked and the SIM of my girl is also an O2 SIM. So what is the problem?
