Weird. I got porn awhile back on mine. Someone had texted me in the middle of the night about a week before and I blew it off as wrong number. Then again a few days after that at work about how she was on her way to rehab treatment or something weird like that. I finally texted back and said you have the wrong number, stop texting me. Then I got the "porn". It was a picture (full frontal nude shot) of a guy!!!
I did report it because they easily could have sent it to one of my kids. We have the family plan and all our numbers are withing one number of each other. The detective called her up and scared the crude out of her. I haven't gotten anything since.
