Connection cannot be set up

A number of factors can prevent connection setup.

Own errors

No SIM card in the module.

The PIN or another block is not unblocked.

The GSM data module is not registered, i.e. it has not or has not yet been able to register in the network.

The M1 was manually set to an unavailable network operator by means of +COPS=1.

The M1 was signed off of the network by means of +COPS=2.

Invalid characters in the dial string.

Dial string contains more than 30 characters.

Command line contains more than 39 characters.

System errors

A connection is already set up.

The call is not answered within 60 seconds after dialing because the distant station:

is not ready,

is not a modem,

does not support the selected operating mode.

The GSM module returns NO CARRIER.

The distant station is busy. The GSM module returns BUSY.

Before the connection can be set up, the GSM module receives a signal from the computer and returns NO CARRIER. If no connection is set up, the GSM module goes on-hook and returns to command mode.

The GSM network does not or does not yet support the fax/data modes. The GSM module returns NO CARRIER.

The GSM module is not registered in the GSM network. It returns NO DIALTONE.
