Same prefix as my husband's number, but still UNKOWN to me, so I do not answer to those pesky callers. No message left, no second call ... it must not have been "that" important! I called number back, a lady answered the phone and I told her that I had a missed call from this number 3 days ago, she informed me that she was out of the country in a cruise and her phone was off the whole time because she didn't want to pay roaming charges. Hummm, that's very fishy!
