Same thing happened to me.  I got a call from 417-660-4619 that said the same as posted below.  I replied that I had a new phone and it wasn't recognizing the number and asked who it was.  I had already looked at the 417 area code and I have family  friends in that area.  The next text asked me to add the sender to my Skype list.  I replied "no, not until the sender identified themselves".  The final text said "sorry...no battery life left".  Yeah right!!

keep getting text from this #...sometimes says "hi!!"  and sometimes says "heyy...add me to yahoo.....i don't text back but they come every week

Got a random text saying to add them to yahoo IM and then when I replied I don't use yahoo messenger they said sorry battery life is going dead :(

I got the same exact message...it's creeping me out :(

I got the same text "Heyaa (first name)". I said hi back thinking with my 16 year old sister-in-law who texts me from her ipod. Then they asked me to add them on yahoo messenger with the screenname kylieflirty17. When I asked who it was, they said, "Sry I have no reception :(" and stopped responding to me. After realizing it was truly a spam thing, I told them to leave me alone. No more texts so far...

Got a Text that said "hey... [and a first name]"

One can forward/report it to the Spam/Unwanted Text department.

text "Heyaaa My first Name."

Sane here! 'heyyy then my name'...

Also received a text that said "Hiii [my first name]"

Did not reply back.

Just got a text from this number. Said "Hiiii Xxx"  (Knew my first name).
That's all it said
