former GM862 family products.

Reference GSM

COPS - Operator Selection

SELINT 2

AT+COPS=
[<mode>
[,<format>
[,<oper>]]]

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

<format>
0 - alphanumeric long form (max length 16 digits)
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

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

+COPS: <mode>[, <format>, <oper>]

AT+COPS=?

Test command returns a list of quadruplets, each representing an operator
present in the network.
The quadruplets in the list are separated by commas:

+COPS: [list of supported (<stat> ,<oper (in <format>=0)>,,
<oper (in <format>=2)>)s][,,(list of supported <mode>s),
(list of supported<format>s)]

where
<stat> - operator availability
0 - unknown
