We’ve had an anti-spam solution for mobile messaging including SMS, MMS, and RCS since 2014, and we include it at no additional charge for T-Mobile customers. How it works:
- Our anti-spam message solution is updated regularly with spam message fingerprints and signatures. Whenever a mobile message is received on the network, it's checked against the anti-spam solution. If a message is determined to be spam or unwanted, we'll block it. Otherwise, the message will be delivered.
- Customers can report spam or unwanted messages by simply forwarding the messages to 7726. We'll reply with a confirmation text and forward the message to the Security Center for analysis. The message and your details are encrypted; your identity won't be shared.
- Replying “STOP” is usually a convenient way to quickly opt out of a message program. However, for unwanted spam texts, we recommend forwarding messages to 7726 and not replying. Similar to picking up an unknown robocall, spammers will use any texted reply (including “STOP”) as confirmation that they've reached a real person.
