PIN Code Management

Operation of the OnCell G2100 Series modem requires the installation of an active SIM (Subscriber
Identity Module) card. The SIM card contains the necessary data to identify the modem to the
network service provider. It is also used to store the GSM/GPRS modem PIN (Personal
Identification Number.) and PUK (Personal Unblocking Key), which are also used with mobile
phones. The PIN helps prevent unauthorized 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

1. Connect the RS-232 port of the OnCell G2100 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.)
2. Type AT+CPIN? and press Enter.
If the OnCell G2100 Series modem responds with "+CPIN: SIM PIN" then the user must enter
the SIM's PIN code.
