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.
