Manage Call Protect options

Avoid unwanted calls

  • Automatic fraud blocking3 detects and blocks potential fraud calls before they reach you. You can see a list of blocked calls in the app.
  • Spam warning4alerts you when a call comes from a suspected spam source. You can also block calls labelled as Spam Risk.
  • Block any unwanted number with your Personal Block list5
  • Send callers you don’t have saved as a contact to voicemail with the Unknown Callers feature.
  • Get a heads up on calls from telemarketers, non-profits, surveyors, account services, and private or political callers.
  • Use SIRI shortcuts to enable call blocking and spam reporting.

To get spam and nuisance call warnings, make sure your device is in an AT&T HD Voice-coverage area and LTE is enabled. Refer to your device manual to find out how to check these settings.

Enable Unknown Callers

Send all callers you haven’t saved in your contact list to voicemail. Here’s how:
  1. Open the app and tap Block.
  2. Tap Unknown Callers, read the requirements, and then tap Send to Voicemail.
  3. Tap Enable. Your contact list will start uploading.
  4. Keep the app open until you see Unknown Callers set to Voicemail.

All other call categories or numbers you choose to block will stay blocked. Any numbers that aren’t stored in your contact list will go to voicemail. This may include calls from emergency responders.

Good to know:
  • You must have an active mailbox for this feature to function correctly.
  • The app updates all changes you make to your contact list every 24 hours for Android® devices and when the app is opened on iOS® devices.
  • We’ll remove your contact list, from the cloud, within 48 hours when you turn off this feature by setting it to Allow.

Block Spam Risk calls

  1. Open the app and tap Block.
  2. Tap Spam Risk and choose Send to Voicemail or Block.

Good to know:
  • We’ll send calls labelled as Spam Risk to voicemail or block them, based on your selection.
  • All other nuisance calls (private, account services, telemarketers, surveys, political calls, or nonprofit) will ring through with a warning if you don’t have a subscription to AT&T Call Protect Plus.

Add numbers to your personal block list

  1. Select Block in the app.
  2. Tap My Block List and tap Add.
  3. Choose one of the following:
    • Enter a Number, then enter a number you want to block.
    • Select from Call Log, then add the number you want to block.
    • Select from Contacts, then check the box next to the contact you want to block.
  4. Tap Block.

You can also go to the Call Log screen, swipe left, and tap Block.

Keep in mind: You can’t manually block unknown numbers or callers who hide their caller IDs, unless you have Call Protect Plus.

We still automatically block potential fraud calls, unless you choose to allow them. When private callers hide their numbers and the app flags those calls as fraud or spam, we’ll display those calls as 000-000-0000 on the caller ID. If your phone has a block list feature, the numbers you block in the AT&T Call Protect app won’t show on that list and vice versa.

Report unwanted calls

  1. Tap the call log entry for the caller you want to report.
  2. Tap Report.
  3. Choose Report Call Type.
  4. Describe the call.

Enable SIRI shortcuts

Shortcuts include blocking the last call received, reporting a call as Spam and reporting a call as Fraud.
  1. From within the app take the actions to:
    • Block a call
    • Report a call as Spam
    • Report a call as Fraud
  2. Go to your device Settings and select Siri & Search.
  3. Under Suggested Shortcuts, tap the + option to add any Call Protect shortcut.
  4. Follow the prompts to complete set up of the shortcut.

  2. Find and tap on the blocked call.
  3. Tap Unblock.
