Same. I get a multiple phone calls in a row at random hours (7am, 930pm,etc). When I answer, no one replies to my hello and then it sounds like someone hangs up. Tried to call back and it said it was disconnected.
Same thing happened twice to me today! I did a little research and found that the phone number comes from the Houston area. It is also apparently under the Metrocall carrier. I went to their web page and was able to search to verify the number but didn't get any additional information. You can also send a page to that number with a little message from their site (you don't have to give your phone number to do so). Hope this helps! http://www.usamobility.com/send_a_message/index.asp
