I have a sim card that when inserting into a mobile phone requires a pin code.
When I use this SIM in EHS6 module, do I need to enter the Pin? if so, how do I do it?
Thanks in advance
You use AT command AT+CPIN.
you can also use AT commands to disable pin usage. Most SIM cards support this
+CPIN: READY //enter SIM PIN
+CLCK: 1 //query SIM PIN status 0 = sim pin disabled
at+clck="SC",0,"1111" //disable sim pin usage
I started out with nothing... I still have most of it.
