No connection with the modem

If there is no communication with the modem take the following steps:

check all external connections with the modem (serial interfaces, USB, power supply).
check that the power supply is correct (see [[{{{model}}} Connectors#Power supply connector|Power supply]]).
check that the COM port is correct.

No connection/communication with the modem

If there is no communication with the modem take the following steps:

Check all external connections of the modem (RS-232 or USB, Power supply)
Verify if the power supply is correct (see [[{{{model}}} Connectors#Power supply connector|Power supply]])
Check if the COM port is correctly parametrized

Receiving ERROR message The modem answers ERROR on AT command in the following cases:

The syntax of typed AT commands is incorrect – check the command syntax in [1]
Parameters of typed AT command are incorrect - type AT+CMEE=1 for enabling wide description of error which occurred. The response now will be in format:

ERROR +CME ERROR: <err> where <err> is a description of the error which has occurred.

Receiving NO CARRIER message There are some common cases when the modem answers NO CARRIER:

If a data/voice/fax connection cannot be established
Right after hanging up the data/voice/fax connection
If there is no connection with the network – check antenna and registration status (see Network registration)
If there is no power supply (see [[{{{model}}} Connectors#Power supply connector|Power supply]])
If modem answers NO CARRIER, you can check extended error code using AT#CEERNET command. A list of codes can be found in AT commands reference guide manual.
