Reieve texts saying "hi Cyndy" , no responce when I ask for id

Same thing happened with me they sent text message said Hey Holly... Then no response when I asked who is this?

Same happen tonight to me but thing but texted "Hello Michelle?". I said "yes" and they replied back "haha if you want to find out who this is you got to add me on yahoo messenger.  My name is txtiechikie14". I didn't.

Same, didn't get a response but they addressed by name. Thought it was my sister in Florida. Never got sms spam before, crazy!

Got a text that said "hi Lindsay." Didn't recognize the number, so I just said "Hey, What's up?" hoping I could figure it out. They then sent one message saying "Opps ... Mi Phone s about to die :(" and another after that saying "add me on Y! msgr textgirlie87" Very weird -_-
