Another question:
The 299 THB Happy Tourist SIM (
http://store.dtac.co.th/en/priceplans/happy-tourist-sim) says:
"Happy Tourist SIM is based on pay as you go. This sim includes everything you need : 100 Baht calling value,
unlimited internet and speical international calling rate"
But then lower on the page it says that Happy Internet costs "
10 baht / MB."
Which is it? Unlimited or 10 THB per MB?
ETA: Or perhaps its 10THB per MB after the "
Free 7-day unlimited internet (3G/wifi)"?
