Write command forces an attempt to select and register the GSM/UMTS network operator. <mode>
is used to select whether the selection is done automatically by the ME or is forced by this
command to operator <oper> (it shall be given in format <format>). If the selected operator is not
available, no other operator shall be selected (except <mode>
=4). The selected operator name
format shall apply to further read commands (AT+COPS?) also. <mode>=2 forces an attempt to
deregister from the network. The selected mode affects to all further network registration (e.g. after
<mode>=2, ME shall be unregistered until <mode>=0 or 1 is selected).
Read command returns the current mode and the currently selected operator. If no operator is
selected, <format> and <oper> are omitted.
Test command returns a list of quadruplets, each represent
ing an operator present in the network.
Quadruplet consists of an integer indicating the availability of the operator <stat>, long and short
alphanumeric format of the name of the operator, and numeric format representation of the operator.
Any of the form
ats may be unavailable and should then be an empty field. The list of operators shall
be in order: home network, networks referenced in SIM, and other networks.
It is recommended (although optional) that after the operator list TA returns lists of supported
<mode>s and <format>s. These lists shall be delimited from the operator list by two commas.
When executing AT+COPS=? , any input from serial port will stop this command.
