Description
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). 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). Refer subclause 9.2 for possible <err> values. 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.
