+COPS - Operator Selection SELINT 0 / 1
former GM862 family products.
Reference GSM 07.07
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
