How do I change what SIM card to use in Galaxy Y duos?
GT-S6102 is a Dual SIM stadby phone. To switch between SIM or USIM cards, open the notification panel (drag your fingers on the screen from top to bottom) and select a SIM card icon.
If you want to use the SIM card on SIM1, tap SIM 1. To use the SIM card on SIM 2, tap SIM 2.
You need to set the correct SIM card setting during outgoing calls and sending SMS. For recieving SMS and recieving calls, it does not matter.
Network settings must be set in each SIM 1 and SIM 2 also.
