Unboxing and setup
HTC Desire 21 pro 5G overview
After taking HTC Desire 21 pro 5G out of the box, familiarize yourself first with the location of the
card tray, controls, and sensors.
1. VOLUME control
2. POWER button / Fingerprint sensor
3. Speaker
4. USB Type-C®connector
5. Microphones
6. nano SIM and storage card tray
7. Front camera
8. Proximity and light sensor
9. Notification LED
You need a 5G NR/4G LTE™plan to use your operator's 5G NR/4G LTE network for voice calls and
data services. Check with your operator for details.
Dual SIM supports both 5G NR and 4G LTE SIM cards. Only one card can use 5G NR at a time.
§If you want to use a case or screen protector, don’t cover and block the proximity and light
sensor. Purchase a case or screen protector designed for HTC Desire 21 pro 5G.
§Avoid liquid or dust from entering the microphone hole to prevent damage to the microphone.
§Don’t disassemble any part of the phone. Don’t try to open the phone or remove the battery by
force. This may damage the phone or its electronics and will invalidate the warranty.

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 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.
3. Push the tip into the hole until the tray ejects, and then pull the tray out.
