Nano SIM Card
HTC 10 uses a nano SIM card. The nano SIM card is preinstalled on HTC 10. If you need to remove
or replace the card, refer to the following instructions.
Use a standard nano SIM card only. Inserting a modified card that is thicker than the standard nano
SIM card may cause the card to not fit properly or damage the card slot.
Slots with Card Trays
There are trays inside the nano SIM and microSD slots that are used for inserting your cards.
When inserting the eject tool into the tray eject holes to remove the card trays, make sure not to press
on the trays to avoid damaging the eject mechanism inside the slots.
Also, if you want to use a protective case, make sure to buy a case that's designed for HTC 10 and
that doesn't block the trays.
Insert SIM Card
