Dual SIM Dual Standby
More recent models feature Dual SIM Dual Standby (DSDS) technology which enables them to have two active SIMs with only one transceiver.
yan pala ibig sabihin nyan, nung binili ko phone ko naka indicate naman na dual sim dual standby. ang pinagkaiba lang nyan sa ios 11 is maaccess mo yung on/off feature nya.
