Last month, the Dtac app (service provider) had a mini-game for Songkran festival that you could play to earn points. You played it with coins you earned from topping up for your phone. It was dumb, but the top 100 winners would win one year of unlimited data, so I gave it a try. App informed me this morning that I had won, and now I’m living that free data for a year life. 13,320 baht is around $425.
