Hey. I am new to the mailing list. I have a Sony Ericsson J100a phone (GSM-850 / GSM-1900)The problem is that I can not make calls and send SMS. I think the problem I have is with the configuration of the stage of Radio the phone, it seems that the SIM card is properly read. I leave it attached the console output of osmocom.
