2.10. AT+COPS Operator Selection
The set command forces an attempt to select and register the GSM/UMTS/EPS network operator using
the USIM card installed in the currently selected card slot. <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 also apply to further read commands (AT+COPS?). <mode>=2 forces an attempt to
deregister from the network. The selected mode affects 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.
The 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.
The test command returns a set of five parameters, each representing an operator present in the network.
A set consists of an integer indicating the availability of the operator <stat>, long and short alphanumeric
format of the operator’s name, numeric format representation of the operator and access technology. Any
of the formats may be unavailable and should then be an empty field. The list of operators shall be in
order: home network, networks referenced in USIM or active application in the UICC (GSM or USIM) in
the following order: HPLMN selector, user controlled PLMN selector, operator controlled PLMN selector
and PLMN selector (in the USIM or GSM application), and other networks.
