Recently I got a txt message:

"Heyyyyy"

Got the same text message about 5 minutes ago. Blocking

Yeah, I just got the same thing, thanks for the posts guys

I received txts like above reports. I am blocking the number now!

I just got a message from the same # it said Hi ;)

I responded back who is this
and almost immediately it said Can u remember who I am ??

Received txt msgs apparently leading to obvious spam or phishing.
1st msg: Heyy :)
I was suspicious immediately but I decided to try and see what was going on. I replied asking who it was. Either they were a VERY fast typist or it was auto-generated the reply:
2nd msg: Do you remember me ??
I replied I didn't have the # in my address book.
3rd msg: How about we talk on y! msngr

I immediately blocked the #. Either it was a spoofed # or compromised.
