I got the same message - really late at night during my holidays (not impressed). I've checked and the same message - different amounts, same ticket numbers, different countries... Total scam. At first I thought it was a breach through Facebook when they were lax. Then I read some posts from people who had gotten the message on phones they had only just activated and no one else had their number yet! Scam, scam, scam. If you return text, you may be billed, or your details used for duplicate SIMs.
Also - interesting, some brave souls rang the number to get 'Carlos' who kept demanding personal details (and a deposit of $500) but hung up when one hero said he was reporting him to the cops! Carlos, you need to get a life... you can't have mine, sorry!
