OnCell G2111/G2151I Series AT Command Set

3-5

persons from using the mobile devices. Users must enter the PIN each time the modem is powered up. The PUK

is used to unlock a SIM card when an incorrect PIN code has been entered three times.

Query the Current PIN Status

Connect the RS-232 port of the OnCell G2111/G2151I Series modem to a host PC. Start PComm Terminal

Emulator with the current communication parameters (default: 115200 bps, 8 data bits, None parity, 1 stop bit,

and no flow control.)

1. Type AT+CPIN? and press Enter.

If the OnCell G2111/G2151I Series modem responds with “+CPIN: SIM PIN” then the user must enter the

SIM’s PIN code.

AT+CPIN? responses

+CPIN: READY Modem is not pending for any password

+CPIN: SIM PIN PIN1 is required

+CPIN: SIM PUK PUK1 is required

If the OnCell G2111/G2151I Series modem responds with “+CPIN: READY” then the SIM security is

disabled, or the PIN for the SIM was entered correctly.

1. If the modem responds with +CPIN: SIM PIN, type AT+CPIN=<pin> where <pin> is the correct PIN.

Press Enter. The following example shows “0000” being entered for the PIN.

ATTENTION

Be careful when entering the PIN codes.

After 3 unsuccessful attempts at entering the PIN, you will need to use the PUK to proceed. PUK

validation

forces the user to enter a new PIN code as a second parameter, and this will be the new PIN code if PUK

validation succeeds. CHV1 will be enabled if PUK1 is correct. Therefore, the application uses the following

command:

AT+CPIN=<PUK>,<NewPIN>

Note that users must apply for PUK codes from the mobile service provider.
