The SIM slot on the side panel supports dual Nano SIM cards. The SIM socket supports the push-push
mechanism, allowing inserting and ejecting the SIM card to be as easy as one push.
1. Locate the SIM card cover on the side
panel.
2. Loosen the twist-screw and remove the
slot cover.
3. Two Nano-SIM cards can be placed on
the top layer. Insert and push the nano-
SIM cards, gold contacts facing upwards,
all the way until they click into place.
4. To remove the nano-SIM card, use your fingertips to push it once, to have the card automatically ejected.
5. Place the door back and tighten the twist-screw.
