Who called from 6602424300

I received a message from this number (text) that said "hi stephanie".  When I replied who is this I got the following:
:) A.dd me on y.a.h.0.0. IM ... sn is zoegirly4
I asked again who this was and got "sry I have no reception :("
I said for them to stop texting this number then.

Have no idea what it is from.

The text said hi Elijah . I received no response when I replied.

3 text messages came in at once saying, "Hi Jon" - which is my name. I did not reply after seeing the posts on this site. It's been about 10 minutes and not repeated texts.

Just got a text from this number. Same as others: message just said "Hi John"

I'm not gonna reply.

I got the same type message to my phone.

Why would anyone do this?
