AT command for SIM Pin retries left
-

Question
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.
Solution
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.
OTHER TIPS
The latest 3GPP spec lists the command you want as +CPINR
