<ci>:
<ci> Description
String type Four byte cell ID in hexadecimal format. Four bytes
are required for UMTS, whereas only two bytes are
applicable for GSM and the two first bytes are then
zeros, for example, 00001A02
Description: Forces an attempt to select and register the GSM/UMTS network opera-
tor. <mode> is used to select whether the selection is done automatically
by the ME or is forced by this command to operator <oper>, given in for-
mat <format>. If the selected operator is not available, no other operator is
selected, except when <mode>=4. The selected operator name format
applies 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, for example, after <mode>=2, ME will be
unregistered until <mode>=0 or 1 is selected. This command is abortable
when registration/deregistration attempt is made.
Read command returns the current mode and the currently selected oper-
ator. 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. A 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 opera-
tor. Any of the formats may be unavailable and should then be an empty
field. The list of operators is 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 are delim-
ited from the operator list by two commas.
