How To Block and Prevent Incoming Calls on the HTC U11 Smartphone

The HTC U11 is an excellent Android smartphone, but like any phone, you may get unwanted calls from telemarketers, robocalls, or other nuisance callers. Fortunately, the U11 has several methods to block and prevent these unwanted calls. In this guide, I will walk you through the various ways to stop incoming calls on the HTC U11 based on my experience as a smartphone expert.

Using Do Not Disturb Mode

The easiest way to silence incoming calls on the U11 is to turn on Do Not Disturb mode. Here’s how:

• Open Settings and tap “Sound & notification”
• Tap “Do Not Disturb preferences”
• Toggle “Do Not Disturb” to ON

When enabled, Do Not Disturb will block all visual disturbances and mute all sounds and vibration during set times. You can customize which contacts or repeated callers can bypass Do Not Disturb and still reach you.

Pros:

• Quick and simple to enable
• Can customize allowed contacts
  Cons:
• Doesn’t identify specific nuisance numbers to block

Block Calls via Call History

You can directly block recent incoming and outgoing numbers from your call history:

• Open the Phone app
• Swipe right to show the call history tab
• Long press the number you want to block
• Tap “Block/Report spam” to block the number

Pros:

• Blocks specific numbers that called you
  Cons:
• Only works on calls already in your history

Use a Call Blocking App

For more advanced call blocking options, use a call blocking app like Hiya or Truecaller. These apps maintain a database of known spam numbers and can automatically block robocalls. You can also easily block specific numbers manually.

Pros

• Automatic spam call detection
• More blocking options like blacklists
  Cons:
• Need to install another app

Via Your Carrier

Most carriers allow you to block numbers through their account portal or by contacting customer service. Keep in mind you’ll typically need to pay a monthly fee for this service.

Pros:

• Blocks calls before they reach you
  Cons:
• Monthly fees may apply
• Need to contact carrier

Conclusion

Blocking unwanted calls on the HTC U11 is easy once you know the various methods. I recommend starting with Do Not Disturb mode and call history blocking which are free and don’t require other apps. But for persistent robocalls from changing numbers, a call blocking app is your best bet. With a combination of these approaches, you’ll gain control over nuisance calls on your U11.
