The mobile computer accommodates two SIM cards and supports dual standby of two
different networks. Both networks will be monitored at the same time, and the phone will
dynamically switch between the two networks during usage. Calls will be placed with either
one of the networks; you cannot switch networks in the middle of a received call or placed
call, or receive or place calls with both networks at the same time.

the SIM 1 card slot. See Installing SIM Card, SAM Card and Memory Card.
