Questions to those that commands not working: - when you've set the number did you put it in the international format or in the local? - when you receive normally SMSs is the number of the sender shown in international or local format? - when you receive the "Location" does your phone switch to GPRS? Could you also put some info like the log and which command you tried? (me too is not that useful) Thanks. EDIT: If you go in the editor in the "Init" tab and press "start" what does the message say?
