AlbertoR_VZW, I am seeing these number pop up in mine and my husbands line of service messages log. They are showing that we are sending a message to the number and that it is a picture/video message, then the number sends multiple messages to us that are picture/video messages. We don't actually recieve anything for the time stamps given. The messaging app that we use is the Verizon messages+ that is provided with the Verizon phones that we purchased. I have a Samsung Galaxy 8 and my husband has a Samsung Galaxy Note 8.
