DSDA (Dual SIM Dual Active) is a dual-SIM design used in phones and cellular data devices where both SIMs can remain active at the same time, allowing simultaneous service (for example, one line on a call while the other maintains data, or concurrent connections where supported). This typically requires more radio resources than DSDS (Dual SIM Dual Standby).
