Inserting 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 and push the tip of the tray eject tool that came in the box (or a small bent paperclip)
into the tray eject hole until the tray ejects, and then pull the tray out.

Make sure to align the cut-off corner of the card to the notch in the holder.
When inserting the nano SIM card, press the card against the tab in the tray to fix it in place.
4. Flip the tray over to the bottom side, and then place either your second nano SIM card or a
microSD card with the gold contacts facing up.
When inserting the nano SIM or microSD card, press the card against the tab in the tray to fix it
in place.

and data services. Check with your operator for details.

Charging the battery
Before you turn on and start using HTC U23 pro, it is recommended that you charge the battery.
§If the battery has been fully drained, you may need to charge HTC U23 pro for several minutes
before powering it on.
§Use HTC's power adapter and USB Type-C cable to charge the battery. When the battery power
is too low, make sure to use the power adapter to charge, not a USB cable connection with your
computer.
1. Insert the small end of the USB Type-C cable into the USB Type-C connector.
2. Insert the other end of the USB Type-C cable into the power adapter.
3. Plug in the power adapter to an electrical outlet to start charging the battery.
4. After you finish charging, unplug the USB cable from your phone first. Hold the part of the
power adapter that's close to the USB port when you unplug the adapter from the outlet.
§Avoid charging the battery in hot environments. As a safety precaution, the battery may stop
charging to avoid overheating.
§When you're using battery-intensive apps such as games or video streaming apps while charging
the battery, your phone may become warmer. This is normal.
§It is strongly recommended to unplug the power adapter from the electrical outlet when not in
use.
Turning your phone on and off
