text me by name "hi M***" but would not respond when I said "who is this?"

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.
