Inserting the nano SIM and microSD cards

  • Use a standard nano SIM only. Don't cut a larger SIM card to fit. It's thicker than a standard nano SIM card and may get stuck in the slot.
  • The microSD card is optional and sold separately.
  • If you're using your old microSD card, make sure you have backups of your content on a computer or cloud storage before inserting the card. You may be prompted to format the card.
  1. Hold the phone face up.
  2. Insert the tip of the tray eject tool that came with your phone—or a small bent paperclip—into the tray eject hole.

    When inserting the eject tool into the tray eject hole to remove the card tray, do not obstruct the tray to avoid damaging the eject mechanism inside the slot.

    Illustration warning not to press the tray when inserting the eject tool.
  3. Push the tip into the hole until the tray ejects, and then pull the tray out.
  4. Do the following to place your nano SIM and microSD™ cards into the tray:
    • With the gold contacts facing down, place two nano SIM cards into the SIM 1 and SIM 2 holders of the tray. Make sure to align the cut-off corners to the notches on the holders.

      Both SIM 1 and SIM 2 cards can be 4G LTE cards. To find out how to set the preferred card for your mobile data connection, see Changing your nano SIM card settings.

    • When you need to use a microSD card, remove your second nano SIM card and then place the microSD card into the outer holder of the tray. You cannot have both the second nano SIM and microSD cards inserted at the same time.
  5. When reinserting the tray, make sure it is facing up so that your cards don't fall out. With the outer card holder between your fingers, steadily slide the tray all the way into the slot.
  6. Make sure the tray is flush with the side of the phone.
Follow the same procedure above to eject the tray and remove your cards. Before ejecting the tray, make sure to unmount your microSD card first. See Unmounting the storage card.
