Select phone network programmatically

Hello

 

I develop a solution for a client which travels between two countries all day long

 

The devices are Motorola MC55

 

If I go to Settings > Connections > Phone Network Setup and choose the "Auto" Active Network Selection Mode, the solution works well in country A + operator A

 

But it does not work well in country B because I'm still working with operator A

 

I have to change manually the operator to get the juice

 

Do I have a way to select the operator programmatically?

 

Regards
