2.1.3.3. AT+COPS Operator Selection
Command Function Write command forces an attempt to select
and register the GSM 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 (+COPS?) also.
<mode>=2 forces an attempt to deregister
from the network. The selected mode
affects to all further 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 representing 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
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.
