nano SIM/UIM card

On HTC Desire 10 pro, use a standard nano SIM/UIM card. Inserting a modified card that is thicker than the standard nano SIM/UIM card may cause the card to not fit properly or damage the card slot.

Inserting the nano SIM/UIM 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.
   
3. Push the tip all the way into the hole until the tray ejects, and then pull the tray out.
4. Do the following to place your nano SIM/UIM card into the tray:
   With the gold contacts facing down, place your nano SIM/UIM cards into the SIM 1 and SIM 2 holders of the tray. Make sure to align the cutoff corners to the notches on the holders.

   

   Note:

   • By default, SIM 1 will connect to the 4G LTE/3G network, and SIM 2 will connect to 3G/2G. To find out how to set the preferred card for connecting to 4G LTE, see Managing your nano SIM/UIM cards with Dual network manager.
   • SIM 2 and SD are labeled on the same holder in the tray. Either place your second nano SIM/UIM card or a microSD card into this holder. Both cards can’t be inserted at the same time.
5. When reinserting the tray, make sure it is facing up so that your cards don't fall out. Slide the tray all the way into the slot.
   
6. Press on the cover that's attached to the tray to close it tightly.

Removing the nano SIM/UIM card

Important: Make sure to switch off HTC Desire 10 pro before removing the card.

1. Hold the phone face up.
2. Insert the tip of the tray eject tool or a small bent paperclip into the tray eject hole.
   
3. Push the tip all the way into the hole until the card tray ejects.
4. Pull the tray out, and then remove the nano SIM/UIM card.
5. To reinsert the tray, center it first in the slot, and then slide it all the way in.
6. Press on the cover that's attached to the tray to close it tightly.
