Received the following text message on my phone last night (see bottom of message.)  My phone automatically highlighted the phone numbers as links, I noticed my fiance's number in the message and it made me curious as to the other number.   I called it, got a message saying the number is not in use, then googled it and wound up here -- noticed a very similar thing with number ending in 8690 on this board, so am posting this to see if anyone has seen anything similar w/8691.    Seems odd that it would contain my fiance's number (and not mine) - although we both use AT&T, so maybe it's something on their end???   Any ideas?
