Important:
You need a 4G/LTE plan to use your operator's 4G/LTE network for voice calls and data services. Check with your operator for details.
Note:
- If you want to use a case or screen protector, don’t cover and block the proximity sensor. Purchase a case or screen protector designed for
HTC U Ultra.
- 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.
