HTC One E8 - Manual (Page 10)

nano UIM and nano SIM cards
HTC One (E8) has two card slots that allow you to insert a nano UIM card and GSM
nano SIM card.
Use standard nano UIM and nano SIM cards only. Inserting a modified card that is
thicker than the standard nano UIM or nano SIM card may cause the card to not fit
properly or damage the card slot.
Inserting the nano UIM and nano SIM cards
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 next to the nano UIM/nano SIM card slot.
3. Push the tip all the way into the hole until the card tray ejects.
4. Pull the card tray out.
5. In SIM 1 holder, place a CDMA nano UIM card or 3G/GSM nano SIM card. In SIM 2
holder, place a GSM nano SIM card.
If the card is NFC-enabled, it must be placed in the SIM 1 holder to be recognized.
6. Insert the card tray back into the slot.
