Hie guys i'm new in this forum. I tried using my SIMCARD which does have credit for the GSM. I power the GSM up but the SIMCARD goes undetected. Shows when the LED blinks on and off at the same rate. I tried using my other friends SIMCARD but nothing changes. GSM i am using is Siemens GSM TC35 Development Board and it is new,about 3 days old. Help please. ASAP.

I don have this development, thinking to grab it during crazy sales, but fail :twisted:

Anyway, have you check the socket of SIM card holder? Insert properly? Orientation correct?
