T-Mobile provides strong tools to protect iPhone users from spam and scam calls. Here’s how to block them effectively.

1. Use T-Mobile Scam Shield

Download T-Mobile Scam Shield from the App Store.
Open the app → sign in with your T-Mobile account → enable Scam Block and Caller ID.
This feature blocks likely scam calls automatically.

2. Turn On Silence Unknown Callers

Go to Settings → Phone → Silence Unknown Callers.
Unknown numbers go straight to voicemail while known contacts still ring.

3. Block Individual Numbers

Open Phone → Recents → tap “i” → Block this Caller to stop further contact from specific numbers.

4. Try Third-Party Spam Apps

Use Truecaller, Hiya, or RoboKiller for additional caller ID and spam filtering.

AvNexo Tip: Combine T-Mobile Scam Shield with iPhone’s Silence Unknown Callers to block nearly all unwanted calls effectively.
