F0402 AT+COPS Operator Selection
Write 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 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 (AT+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,
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 should then be an empty field.
The list of operators shall be 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 shall be delimited from the operator list by two commas.

The value of < on/off > is nonvolatile, and factory value is 0. 2. For automatic time and time zone update is enabled (+CTZU=1): If time zone is only received from network and it isn’t equal to local time zone (AT+CCLK), time zone is updated automatically, and real time clock is updated based on local time and the difference between time zone from network and local time zone (Local time zone must be valid). If Universal Time and time zone are received from network, both time zone and real time clock is updated automatically, and real time clock is based on Universal Time and time zone from network. |

| <tz> | Local time zone received from network, it’s an integer, and the format is “±tz”. |
| <dst> |
Network daylight saving time, and if it is received from network, it indicates the value that has been used to adjust the local time zone. The values as following: 0 No adjustment for Daylight Saving Time. 1 +1 hour adjustment for Daylight Saving Time. 2 +2 hours adjustment for Daylight Saving Time. |
| <time> |
Universal time received from network, and the format is “yyyy/MM/dd,hh:mm:ss”, where characters indicate year (two last digits), month, day, hour, minutes and seconds. NOTE: Here in,<time> is Universal Time or NITZ time. |
