How T-Mobile Users Can Reduce Unwanted Calls

Unwanted calls, such as spam and scam calls, are a common nuisance for mobile users. T-Mobile offers several tools to help its customers reduce these interruptions.

What Built-in Features Does T-Mobile Offer to Block Unwanted Calls?

T-Mobile provides a suite of features designed to identify and block unwanted calls:

  • Scam Shield: This free service includes Scam ID, which labels potential scam calls, and Scam Block, which prevents these calls from reaching your device. You can activate Scam Block by dialing #662# from your T-Mobile device or through the T-Life app. (t-mobile.com)

  • Caller ID: Displays the caller's information, even if they're not in your contacts, helping you identify unknown callers. (t-mobile.com)

  • Scam Reporting: Allows you to report suspicious calls, contributing to the improvement of T-Mobile's scam detection system. (t-mobile.com)

How Can I Block Specific Numbers on My T-Mobile Device?

To block individual numbers:

  1. Open the Phone app.
  2. Tap the three-dot menu and select "Settings".
  3. Choose "Blocked numbers".
  4. Tap "Add a number" and enter the number you wish to block.

Alternatively, you can use the Family Allowances feature to block calls and texts from specific numbers. Manage this by logging into your T-Mobile account. (t-mobile.com)

Are There Third-Party Apps That Can Help Block Unwanted Calls?

Yes, third-party apps can offer additional protection:

  • Robokiller: This app provides 99% effective protection against robocalls and robotexts. It uses machine learning to identify and block spam calls and texts, and features Answer Bots that waste telemarketers' time. Robokiller is available for $4.99 per month or $39.99 per year, with a 7-day free trial. (robokiller.com)
