Set Up Your Phone Cards

Use your extra card slot to set up a second nano-SIM (on supporting models) or an NM card for more storage.

To configure dual SIM settings, go to Settings > Wireless & networks > Dual SIM settings, and choose your default mobile data and calling SIMs.

Note: Turn off your phone before installing the cards, check that cards are placed in the correct slots, and make sure to insert the card holder back into your phone correctly.
