Receive evening phone calls from this number, to a wifi phone/text app (pinger) phone number that I downloaded to my iPad. No one picks up on call back, just hear music. I'm going to block the number cause i don't have a clue who it is, and the only ppl that have this iPad wifi number of mine, are my husband and kids. (No AT&T service where I'm located, and talking over wifi is the only way to communicate with my family--when the wifi works--)
