Syntax:   

AT+CPOL

=  [<index>] [,<format>[,<oper>[,<GSM_AcT>,<GSMcomp_Act>,<Utran_Act>]]] 

 

The different possibilities are: 

AT+CPOL = <index> to delete an entry. 
AT+CPOL = , <format> to set the format used by the read command (AT+CPOL?). 
AT+CPOL = , <format>, <oper> to put <oper> in the next free location. 
AT+CPOL = 

<index> , <format> , <oper> to write <oper> in the <format> at the <index>. 

AT+CPOL = 

<index>,<format>,<oper>,<GSM_AcT>,<GSMcp_Act>,<Utran_Act>  

 

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). 

  Per default if Acces technology parameters are not given, the GSM access technology will be 

chosen. 

 

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, 

EF_OPLMNwAct, EF_HPLMNwAct.
