Does anybody use a DUAL SIM phone (two SIM cards in one phone)?

[Italianoleone]

Hi!

I have a DUAL SIM phone which means I have two SIM cards in the phone. Touch&Go+ on my 2013 Auris always connects to the first SIM card even though it has mobile data connection disabled. I don't know how to "introduce" a second SIM card to the car.

Does anybody else use a DUAL SIM phone and has any advice on usage?

Thanks.
