How is PIN code given in GSM shield


I am starting a new GSM shield + Arduino project. My new Prepaid GSM account has a PIN code, but PIN codes are not mentioned in the code examples.

I'm just talking to myself.

I added ret_val = gsm.SendATCmdWaitResp("AT+CPIN=PINC", 1000, 100, "", 1);

into Void setup block. There is plenty things to check, like how to disable sim code and how to know when it is needed.

but it the sim card in a phone and disable it...

jus a thougth...

i have no experience with that kind of electronics.
