MC55 AT Command Set

8.2 AT+COPS

Command Description

s

mobile

The test command returns a list of quadruplets, each representing an operator present in the network. Any of the formats may be unavailable and will then be an empty field (,,). The list of operators comes in the following order: Home network, networks referenced in SIM, and other networks.

The read command returns the current <mode> and the currently selected operator. If no operator is selected, <format> and <oper> are omitted.

The write command forces an attempt to select and register the GSM network operator. If the selected operator is not available, no other operator will be selected (except <mode>=4). The selected operator name format will apply to further read commands (+COPS?), too.
