When, for example, making a call, you can choose which SIM to use by tapping the
corresponding SIM 1 or SIM 2 button after you dial the number.
Your phone shows the network status for both SIMs separately. Both SIM cards are available
at the same time when the device is not being used, but while one SIM card is active, when, for
example, making a call, the other may be unavailable.
