3.6. Operator selection
To select the operator, two possibilities exist :
The mobile enters the manual mode, and then try to find an operator
which is indicated by the application. If it finds and registers correctly, then
the mobile stays in idle mode.
The mobile enters the automatic mode, and then try to find the home
operator. If it finds and registers correctly, then the mobile stays in idle mode ;
if not, the mobile looks itself automatically for another network.
To force an attempt to select and register a GSM network operator, the
application must send the following command :
The first parameter indicates either automatic (value 0) or manual
(value 1). The second parameter indicates the format of the third parameter.
The only format supported by Wavecom module is the numerical format
(value 2). The third parameter is the operator identifier (MCC3 MCC2 MCC1
MNC2 MNC1).
