Q:

AT command for SIM Pin retries left

Does anyone know an AT command that will allow me to query how many retries of entering PIN on a SIM card before it locks me out?
I've tried AT+CPIN? but that does not give me how many times I can enter the PIN before I need a PUK.
How do normal phones do it?
Thanks in advance.

A:

The latest 3GPP spec lists the command you want as +CPINR

A:

It's not part of the ETSI spec so it depends on the equipment your using.
It's most often called the "Pin Counter" and can be read via AT^SPIC however your best bet is looking for "Pin Counter" in the devices AT command documentation.
