TLDR : Answer Summary
Several users shared their experiences with unlimited data SIM card options in Thailand, particularly recommending AIS and True. Plans can range from a few months to a year, with various pricing and data speed details. AIS offers both prepaid and postpaid options with prices varying from 1,500 to 3,500 baht for different durations. Users highlight that AIS has extensive coverage and good customer service. Additionally, some commented on the availability of these SIM cards at airports and convenience stores like 7-Eleven, advising to avoid tourist packages. A few users mentioned experiences with data speeds exceeding what they paid for.

AIS is the way to go. Second to that is DTAC. The work about as well in major population areas but AIS works better out in the country.

 If you already have a DTAC sim it’s probably easier to keep it and ask for a similar data add-on package. In my case, AIS add-on pack was available within their app. True didn’t advertise their’s, I messaged customer service who sent me the code to apply it. In both cases, I needed to top-up my account in advance to permit the purchase. If you decide to go for AIS or True it’s best not to buy at airport. They try to sell tourist ‘specials’ which are not what you’re looking for. Buy a pre-paid SIM from

 They sell the 1-2-call SIM cards in 7-Eleven and othor places. But best to ask in an AIS shop about it and they will set it up for you.

 I couldn’t believe what I was seeing either! I tried uninstalling and reinstalling and other speed measuring apps. To be fair, the speed does vary considerably but it’s always a lot faster than what I’ve paid for so I’m very happy.

 really depends on what your require.....ie data calls. Then you look for a plan to match your needs. AIS (been with them just over 10 years) have many unlimited data plans renewable monthly and great coverage
