Using a Dual SIM device
A Dual SIM device enables you to do the following:
Receive incoming communications via both SIM cards.
Select the number from which to send outgoing communications, or have the option to select a SIM card each time
you place a call.
Forward calls received via SIM 1 to SIM 2 when SIM 1 is unreachable, and vice versa. This function is called Dual
SIM reachability. You must enable it manually.
Before using multiple SIM cards, you need to enable them and select a SIM card which will handle data traffic.
