(See table on next page)
This command edits (or updates) the SIM preferred list of networks.
This list is read in the SIM file selected by the command AT+CPLS.
<index>: position of the operator record in the Sim preferred operator list. Use AT+CPOL=? to view the
<format>
<oper>: characterstring or integer (see <format>) indicating operator identifier.
<GSM_AcT>: GSM access technology
<GSMcomp_Act>: GSM compact access technology
<Utran_Act>: UTRA access technology
AT+CPOL= [<index>] [,<format>[,<oper>[,<GSM_AcT>,<GSMcomp_Act>,<Utran_Act>]]]
The different possibilities are:
To write <oper> in the <format> at the <index> precising the access technology (in the case of
EF_PLMNwact, EF_HPLMNwact or EF_OPLMNwact is present).
Note:
The supported format are those of the +COPS command.
The length of this list is limited to 85 entries for EF_PLMNsel, and 51 for EF_PLMNwAct,
