Block unwanted numbers, calls, and text messages

Getting tired of nagging calls or text messages? You can block unwanted numbers from a specific number. You can also block text messages you no longer want to receive.



Block calls and texts on your phone

If a subscription service is sending you too many messages, visit the promotion or newsletter's website to opt out or adjust your settings.


If your phone doesn't offer blocking options, our Calling Services might help. This service let's you block calls and texts from specific numbers. You can manage Family Allowances online through My T-Mobile or from your phone with the My Account app.



Activate scam protection

If you’d like to block calls from known scammers, you may choose to enable Scam Block. With Scam Block, all calls from known scammers are blocked with no ring-through to your phone. Scam Block will block scammers only, not spammers or telemarketers. This service is free for T-Mobile post-paid customers.


To activate Scam Block and get more details on T-Mobile’s scam protection offerings, check out our Call Protection page. Note: enabling Scam Block may inadvertently block desired calls, but you can disable Scam Block at any time.


Let us know if there is a number that you think should be added or removed from our scammer list by reporting the scam call.

Stop telemarketing calls

If you receive unwanted sales calls, add your phone number to the National Do Not Call Registry. It may take up to 31 days for this to take effect. Visit


If you are already on the National Do Not Call Registry but continue to get sales calls, file a complaint with the FTC.



Report spam text messages

Spam is unsolicited text messages sent indiscriminately to your mobile phone. It can be a simple text message, a number to call, a link to a website for more information, or a link to a website to download an app.


If you receive text message spam, report them to T-Mobile:


  1. Forward the message to 7726 (which spells "SPAM" on most phone keypads).
  2. You’ll receive an automated message asking you to reply with the 10-digit phone number of the original sender.
  3. After you submit the sender's phone number, we'll reply to confirm we've received the number.



Change your phone number

You can change your number to stop unwanted phone calls or text messages, but do this as a last last resort. See how to change your phone number to get started.
