+COPS - Operator Selection

AT+COPS=

[<mode>

[,<format>

[,<oper>>[,< AcT>]]]]

Set command forces an attempt to select and register the GSM\UMTS

network operator.

<mode> parameter defines whether the operator selection is done

automatically or it is forced by this command to operator <oper>.

The operator <oper> shall be given in format <format>.

Parameters:

<mode>

0 - automatic choice (the parameter <oper> will be ignored) (factory

default)

1 - manual choice (<oper> field shall be present)

2 - deregister from the network; the MODULE is kept unregistered until a

+COPS with <mode>=0, 1 or 4 is issued

3 - set only <format> parameter (the parameter <oper> will be ignored)

4 - manual/automatic (<oper> field shall be present); if manual selection

fails, automatic mode (<mode>=0) is entered

0 - alphanumeric long form (max length 16 digits)

1 - short format alphanumeric <oper>

2 - numeric 5 digits [country code (3) + network code (2)]

<oper>: network operator in format defined by <format> parameter.

Note: <mode> parameter setting is stored in NVM and available at next

reboot, if it is not 3 (i.e.: set only <format> parameter).

Note: if <mode>=1 or 4, the selected network is stored in NVM too and is

available at next reboot (this will happen even with a new SIM inserted)

Note: <format> parameter setting is never stored in NVM

<AcT> access technology selected:

0 GSM

2 UTRAN

AT+COPS? Read command returns current value of <mode>,<format> and <oper> in

format <format>; if no operator is selected, <format> and <oper> are

omitted
