...well, maybe it's just my own stupidity. 1-2-Call (and the other carriers as well, I assume) now have a feature that lets you transfer some of your credit to another phone. Thus, when that sweet, innocent thing sidles up to you in the bar or beach and asks to "play game" on your phone, be aware that he might just be transferring credit.

Overachiever that I am, I managed to get hit twice, 30 minutes apart, for a total of 200 baht. You'll get a confirmation text from the carrier, but who the hell checks those during their nightly foray? And, the really savvy lads can probably delete the confirmations before you see them.
