Call protection by Threat Protection for Android

Introduction

Call protection, a feature of Threat Protection, flags potential scam calls before you answer. It screens incoming numbers and shows a clear warning so you can decide whether to ignore, decline, or send the call to voicemail instead of answering.

How does call protection work?

  • Number reputation check – When a call comes in, the feature instantly checks the incoming number against a constantly updated database of known scam and telemarketing operations.
  • Real-time alert – If the number is identified as a potential threat, a clear warning label appears on your incoming call screen before you answer.
  • You stay in control – The feature provides a warning but never automatically blocks a call. You always have the final decision to answer, decline, ignore the call, or block the number yourself.
  • Privacy-first design – To protect your privacy, this feature only analyzes the caller’s number. It never accesses, listens to, or stores the content of your conversations.

Requirements

Here's what to do

  1. Open the NordVPN app.
  2. Tap the shield icon at the bottom of the NordVPN app.
  3. Toggle on "Call protection."
  4. Tap "Continue."
  5. Select NordVPN as the default caller ID & spam app.
  6. If prompted, allow the NordVPN to manage phone calls.

In case you decide to change the Caller ID & spam protection back to default, follow these steps.
NOTE: Android 10 users may be asked to grant an extra permission during this process. Meanwhile, newer versions of Android require fewer permissions.

Additional tips

  • If Call protection isn't working, the first step is to confirm that NordVPN is still set as the default "Caller ID & spam app" in your phone's system settings.
  • This feature provides a warning but never automatically blocks a call. If a number you recognize is flagged as a potential scam, you can still choose to answer it.
