For about 2 months now, our text message usage log shows there has been hundreds of incoming text messages from two "Atlanta, GA" numbers: 404-455-0118 and 404-455-0112. We have never actually recieved anything from these numbers (nothing in our phones). It just shows up on the usage history.
I contacted the # and they are out of service, but it shows on our log that we're receiving well over a dozen texts from them EVERY day. We don't know anyone from GA and that's on the other side of the country from us. I blocked these # from our family accounts, but they're STILL showing up on the usage log regularly. They appear randomly, at all times of the day and night, etc. No phone calls or outgoing messages, though.
