Interfacing TC35i GSM problem


Recommended Posts

Hi,
I am interfacing a TC35i GSM module.
I have a problem which is :
When there isn't SIM I can connect to serial port and send and receive AT command.
But when I insert SIM card it is going off after a few seconds. during that shot period of time I can send AT command and it show SIM ID too, There isn't any output to serial on shutdown.
I would appreciate if you can help me.
