into the tray eject hole.
3. Push the tip all the way into the hole until the tray ejects, and then pull the tray out.
Dual SIM model: SIM 2 and SD are labeled on the same holder in the tray. Remove your
second nano SIM card when you want to use your microSD card. Both cards can’t be inserted
at the same time.
4. Place your microSD card—gold contacts facing down and narrow side facing in—into the SD
holder of the tray.
