1.20. PLMN selection +COPS
Set 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 MT or is forced by this
command to operator <oper> (it shall be given in format <format>) to a certain access
technology, indicated in <AcT>. If the selected operator is not available, no other operator shall
be selected (except <mode>=4). If the selected access technology is not available, then the same
operator shall be selected in other access technology. 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 network registration (e.g. after <mode>=2,
MT shall be unregistered until <mode>=0 or 1 is selected).
This command should be abortable when registration/deregistration attempt is made.
Read command returns the current mode, the currently selected operator and the current Access
Technology. If no operator is selected, <format>, <oper> and < AcT> are omitted.
