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 received this message today, also in two parts. Somethin weird is that I thought the numbers wit 555 didn't exist... but I received q message from it. I'm using the LG Rumor with virgin mobile. By chance every text message received with Virgin are Free!

girlfriend got the same thing, must be some east indian pranksters.  haha.. oh man their good.

I received three in a row of these messages on Bell Prepaied Sanyo phone.Whasss up??

I have recieved over 12 of these random textular messages.

I have the same problem ! I recently bought the Samsung vice from Virgin Mobile and got 7 of these strange text ! It's particulary strange because number with 555 are use in movies because they don't exist at all, so I don't Know why this is happen
