Message Blocking

Message Blocking is a free T-Mobile service that allows you to block messages to and from your phone, to help you avoid unwanted messages. The Primary Account Holder can add or remove the Message Blocking.


If getting the error 'Message Blocking Active' when messaging, see Text message troubleshooting.

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.



Block messages from a specific number

You can block messages from a specific number by adding Family Allowances to your account. Once Family Allowances is added, you can change your settings to block messages from a specific number.
