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...
