Calls

Caller ID spoofing is the process of purposely changing the caller ID to any number other than the calling number. Scammers can use a fake number from an area code close to or familiar to you, to make you more likely to assume that the call is from a local business and get you to answer the call.

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 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 will incur charges on your T-Mobile account.

Tips to avoid these scams

• 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, you can Contact Us to

Messages

• 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 click on a link in a text message unless you're certain that the message is from a trusted source.
