In preparation for the multi-SIM setup, we need a way to tell whether a given SIM card is active or not in the system. On systems with one single SIM slot, the available SIM card will always be active. On Multi-SIM Single-Standby setups we may have multiple SIM slots with multiple SIM cards, but only one of them will be active at any given time. On Multi-SIM Multi-Standby setups we may have multiple SIM slots with multiple SIM cards that may be active at the same time. E.g. the QMI protocol allows up to 5 different active SIM cards (primary, secondary, tertiary...).
