If you ever get a phone call from a number that appears local, but you don’t recognize it and it ends after one ring? Do NOT call them back! State Attorney General Ashley Moody says this is how the “One-Ring Phone Scam” works. Though they look local, the calls are actually coming from outside the United States. When you call back, the scammer will try to keep you on the phone. That’s because the scammers are using a service that charges a connection fee and a per-minute charge. The scammers will receive a portion of these fees and you’ll be the one stuck footing the bill.
