Block scams and spam

How T-Mobile Can Help

  • T-Mobile offers scam protection with Scam ID and Scam Block, and caller ID included at no additional charge.
  • The T-Mobile Scam Shield app lets you easily manage your free mobile scam protection tools from T-Mobile. You can activate Scam Block and Caller ID, see the calls T-Mobile has blocked on your behalf, mark favorites, and report likely scam calls.
  • You can block some text messages using Message Blocking.

What you can do

  • Avoid using your T-Mobile number for non-T-Mobile contests, promotions, or newsletters.
  • Never download applications from unauthorized app stores.
  • Do not swap applications with friends using memory cards.

Buying a used phone?

  • Purchase from a reputable retailer or manufacturer. 
  • Make sure the phone has been cleared. If you find any information stored in the phone, it may not be safe.
  • Check the device's IMEI hasn't been reported stolen on the Cellular Telecommunications and Internet Association free stolen phone checker tool​.


Types of call and message scams and what you can do


One Ring Call back scam is when an incoming call rings once before hanging up. You get a call from a number that looks like it is from the US but is not. For example, "649" goes to the Turks and Caicos and "809" goes to the Dominican Republic. Calling these numbers back may incur charges on your T-Mobile account.

Tips to avoid these scams
  • Turn on Scam Block.
  • Don't answer or return any calls from numbers you don't recognize.
  • Beware of callers from unknown numbers who immediately ask, “Can you hear me?” Disconnect or answer, “I can hear you.”
    • If you say "yes," the caller could record your response and reuse it elsewhere.
  • Before calling unfamiliar numbers, check to see if the area code is international.
  • If you do not make international calls, Contact Us.
  • Don’t act on any message if you're suspicious of the content, even if it looks like it's from someone you know.
  • Never open a link in a text message unless you're certain that the message is from a trusted source.
  • If you have opened a suspicious link, change your T-Mobile ID password ​and other personal accounts, like banks and social media.

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.

  • Messages sent from 3700 to 4299 and 9701 to 9901 are coming from a third party, usually an email provider.
    • These messages are how email is delivered to your as a text message.
    • Messages can also be delivered as an MMS and will show the sending email address.
  • You can opt out of subscription spam by visiting the promotion or newsletter's website.
    • Reply to text messages with STOP, END, CANCEL, UNSUBSCRIBE, or QUIT.
    • Don’t reply to unwanted messages if you’re unsure who sent it or it doesn’t provide an opt-out option.
    • After opting out, you may receive one more message confirming your request to opt out.
  • Copy the original message and send it to us at 7726 (“SPAM”). 
    • Select the text and copy the message.
    • Create a new message to 7726, paste the copied text, and send.
    • We'll reply with a confirmation text that will forward the message to the Security Center for analysis. The message and your details are encrypted, your identity won't be shared.
  • If the above tips don't work for you, you can change your phone number.
