Anybody else getting floods of texts from 555-111-0000?

I'm getting flooded with texts from 555-111-0000, sometimes a dozen a week, sometimes a dozen a day. Texts are always long strings of digits and letters.  Anybody else getting this? any idea what it is about?

Update: I had my son send me a couple of MMS to test mmsd/chatty, and it looks as if the 5551110000 texts are MMS messages, coming from the ATT system.
