6 TROUBLESHOOTING
This section suggests the possible solutions for common problems encountered when using the
iTegno 3800 GPRS modem.
6.1 Is my modem powered up?
Check whether the LED on the modem is lighted up. If it is not lighted up, check whether the
modem is properly connected to the PC via the USB cable.
6.2 Is my SIM Lock enabled?
Use AT+CPIN? to request for PIN Status, or
AT+CLCK=”SC”,0,”password” to disable SIM LOCK.
6.3 What is my SIM card PIN code?
If you have forgotten or lost your PIN code, or, you have not received such a code, please contact
your network service provider for assistance.
6.4 Unable to register to the network
Check the modem Status Indicator LED. The LED should be blinking if the modem is registered to
the network.
Use AT+CREG? to request for registration status.
Check the signal strength of the network using AT+CSQ command. You should receive a +CSQ
response (+CSQ: <rssi>, <ber>). If the rssi value is 99, it means the network is unknown or
undetectable. The ideal rssi value should be 8 to 31. An rssi value less than 8 has weaker signal
strength.
