Someone texted me from this number and knew my name. They said " hi Daniel!!!" They would not identify themselves when I asked who they were. I am blocking the number.

Text said:  "Hello (my name)??"

Other posters say they have had success in forwarding these illegal texts to 7726. They are picked up by your cell phone carrier who will ask you to send them the phone number so they can investigate and have spam filters installed to block the texts. The following article tells you everything you need to know:

Security company Cloudmark created a spam messaging reporting service that nation’s major wireless carriers agreed earlier this year to start using. Now, customers of AT&T Mobility, Verizon Wireless, T-Mobile, Sprint and others can forward their text spam message to 7726. The mobile phone carrier will ask customers for the phone number that’s linked to the spam message so they and Cloudmark can start investigating.

Me:who is this?
Them: do ya use yahoo messenger?!? Cause msg me my username is textchick33
Me: No i dont have one and who is this?
Them: omg my phone's about to die ;(
Me: one does not simply have my phone number and spell my name correctly
(then no answer, i looked up the number on google, and apparently it has been happening to other people the exact same way, im starting to think that it is an advertisement for the yahoo messenger.)

Happened to me too a few hours ago... same exact thing...
