I got the same thing on a Samsung Instinct.  And only my dad has my number as it is brand new.  Got for in a row - same script as above.  Very odd.  Plus I have free incoming text - so i doubt that its a money grabbing scam by providers.
Very strange!  Even more strange is the 3 websites with this discussion about the same number that doesn't exist!

I got four of these non-sensical text message from (416) 555-2121 all at the same time.

I got 4 text messages of the same sort and i'm with Virgin using a Blackberry 8530. if this costs me anything i'm definately reporting this.

Received these random nonsensical texts on my Bell Blackberry Storm.  Contacted Bell Help Desk, they had never heard of the problem.  Started on a Tuesday afternoon, received a TON of them and none afterwards.  Weird.

i have lg rumor 2 with virgin and got the same 2 messages today..what does it mean? i texted back but it said the text had failed

and virgin mobile is based off of bell mobility.  coincidence that bell and virgin users are being texted.  I activated my phone online by myself.  I don't receive any of these bu***hit calls.  when you activate your phone at the kiosk(s) They send your number off to the marketers.
