Who called from 4439389739

I received a text message from this number asking me to add them to my yahoo messenger, name textflirt349. I didn't respond after that.

I know a couple people who have asked me to look it up because they, too, have gotten it on their phones. It's stupid. I went on Yahoo Messenger, clicked "Action", then "Send IM" and put TextWoman21.... then reported as SPAM. Forget that, I don't even have a smart phone so it's not like i signed my number up. I hate that [***]!

I got the same text. They said hi then my name (what the hell) I asked who it was, they said my phones dying add my to Y mess I textflirter78....I got a cell phone for a reason people and how did they know my name

I also go this message thee phone number was different but what does it mean?
