AIS (1-2-call)

You can buy this SIM card in any shop or 7-11. Ask for a 1-2-call SIM, not a data SIM. The data SIMs are something else and really have no advantage over getting a 1-2-call SIM and enabling EDGE/GPRS.

You add value by buying top-ups everywhere.

For Internet access, you call AIS at 1175 and tell them you want to enable GPRS service, they need to turn it on. At that time, you should subscribe to one of the data packages because the default charge for data is 1 baht per minute.

EDGE/GPRS Package Monthly Package
3 hrs. (180 mins) 30 baht Dial *138*0331#
6 hrs. (260 mins) 50 baht Dial *138*0332#
20 hrs. (1200 mins) 100 baht Dial *138*0333#
100 hrs. (6000 mins) 350 baht Dial *138*0334#
Unlimited 999 baht Dial 1175

These amounts are subtracted upon subscription, then again on the same day in the following month. If you want to cancel or add a package, just call AIS.

All data is by the minute. You can check the balance of your data package at any time by pressing *139#

APN is: internet (for iphone) but AIS will send the settings to your phone upon request.

I have tried all providers in Thailand, I can tell you the AIS has the best overall EDGE coverage in the entire country. There are a few malls in Bangkok that have limited 3G service.
