Problem with SIM 300 - +CMS error: 517

[Krishna Patil]

I bought SIM 300 V 7.03 , connected to PC via RS -232 , using hyperterminal , AT commands like AT,ATI are working but error +CMS error : 517 comes when trying t send SMS and also after powering

+CPIN: NOT INSERTED

+CFUN: 1

I googled it , that means " SIM not inserted " . But i inserted SIM in proper position ,

Voltage between Pin 1 and pin 5 of sim connectors is zero. What might be wrong ? or module fault ?

Re: Problem with SIM 300

There maybe some problem with the SIM HOLDER slot connections.

Check its connections.

If any problem, try soldering it.
