Use this page to identify, report, and prevent spam and scams on your T-Mobile device and account.

Text Message (SMS) spam and scams

Text message (SMS) spam is any unwanted texts, often from companies, news sources, banks, restaurants, etc., you may receive. SMS spam should not be confused with Self-service short codes, which include T-Mobile short codes that we use to keep you informed about your account.

  • T-Mobile is committed to fighting mobile spam and encourages our customers to report unsolicited messages to us for investigation. If you receive an unsolicited message, please forward it to the Spam Reporting Service following the steps on this page that correspond to your device.
  • We automatically forward the message to the Security Center for analysis. The Security Center is a global system, run by a vendor on our behalf, that helps protect mobile phone subscribers from spam, fraud, and malware. The Security Center system is linked to a global database that tracks potential spam messages. The information reported to the Security Center may be shared with government agencies that work to combat spam and prevent fraudulent, deceptive, and unfair practices.

Report spam messages: Apple iOS


Reporting junk or spam doesn’t prevent the sender from sending messages, but you can block the number to stop receiving them. The option to report spam messages on iPhones is available on devices running iOS 16 or later. For older devices running older iOS versions, follow the steps to forward the message to 7726.

To report spam:

  1. Open the conversation with the spam message and scroll to the bottom.
  2. Choose Report Junk > Delete and Report Junk.



Report spam messages: Android


Most Android devices come preinstalled with the Messages by Google app. If your device comes with a different messaging app, you can download the Messages app from the Google Play Store. If you choose not to change your messaging app,  follow the steps to forward the message to 7726.

To report spam:

  1. In the Messages app, select and hold the spam conversation.
  2. Select Block > Report Spam > OK.

Report spam messages by forwarding to 7726 (All devices)


By reporting SMS spam, you are helping us identify spam operations. There is no charge to report T-Mobile spam. Messages forwarded to 7726 do not count toward your plan. 

  1. Forward the message to 7726 (which spells “SPAM” on most phone keypads). Please don’t edit the message or add any comments.
  2. If you don’t have a forward option:
    • Long press on the message text and select Copy.
    • Create a new message to 7726.
    • Paste the copied text and send it.
  3. We will reply to your message with an SMS confirming we have received it.
  4. We will use this information to help identify the spam operations and take appropriate action.


Scam ID & Scam Block

Scam ID and Scam Block are industry-leading free scam protection tools deployed on the T-Mobile network to keep our customers safe from scammers.

  • Scam ID automatically displays "Scam Likely" and the number that is calling on suspected scam calls
  • As an additional network level identification feature, customers will also see some calls labeled as Telemarketing, Political, Nuisance etc. These are automatically identified at T-Mobile's network level and displayed to our subscribers to help them in making informed decisions on which calls they would like to interact with.
  • Scam ID also catches spoofed calls because T-Mobile reviews beyond the incoming number and tracks actual call behavior. 
  • Scam Block automatically blocks all "Scam Likely" calls before they ever reach your phone, so you never even get them.
  • Network-level protection has been added to stop the increasingly common “Neighborhood Spoofing” and prevent hijacked numbers (where scammers temporarily match the area code and 3-digit prefix of the person they are targeting) from reaching your phone.
  • The free website gives businesses the ability to register their business number(s) and name, so their calls to customers are recognized as legitimate.

Turn on/off Scam ID & Scam Block


Scam ID and Scam Block are free of charge with your T-Mobile postpaid plan. You can turn them on or off at any time. Scam ID is free and automatic for all T-Mobile customers; no action required.

Anonymous callers


The FCC mandates that mobile carriers allow callers the ability to block their caller ID information and place anonymous calls. T-Mobile is obligated to honor the privacy of the caller in these circumstances. T-Mobile can't block anonymous calls or override the privacy choice of the caller, but you may choose not to accept them. To make an anonymous call yourself, dial *67 before dialing the number you are calling.

For more information about privacy and security, refer to our Privacy Center.


Verified callers


T-Mobile makes it easy to know who's calling with caller verification!

  • We follow the FCC standards of STIR and SHAKEN to help fight scam callers industry-wide in addition to our own call authentication.
  • Number Verified is available on capable devices and will indicate that the incoming number has been validated and authorized. Review the Tech Specs for individual devices to determine if this service is available.
  • Spoofed calls occur when scammers illegally mimic originating telephone numbers. Number Verified helps confirm if the calling number is accurate and not impersonating another phone number.
