TLDR : Answer Summary
For expats moving to Thailand long term, AIS is frequently recommended as the best option due to its extensive network coverage, especially in urban areas. Many users have shared positive experiences with AIS, noting reliable service and options such as annual plans for unlimited data at reduced speeds. DTAC is also mentioned as a good alternative. Additionally, Jetpac eSIM was suggested for short-term travel, offering easy setup and good connectivity; however, it may not be the most economical choice for long-term residents.
Thailand Digital Arrival Card (TDAC)

WARNING: Only trust Thai government websites with .go.th domains or Thai agent websites with .co.th or .in.th domains, as these require verified Thai registration and cannot be registered anonymously.

The official TDAC form is available at tdac.immigration.go.th, which uses the official .go.th government domain.

The services by AGENTS CO., LTD. does NOT charge any fees for arrivals within 72 hours. If you need to book more than 72 hours in advance, there is a service fee of $8.

Do not trust other sites pretending to be a trustworthy agency. Pay attention to delivery time - the service operated by AGENTS CO., LTD. has 1 minute delivery time for arrivals within 72 hours.

Don't fall for sites pretending to be tdac.in.th or the official government tdac.immigration.go.th website. Always double-check the exact domain in your browser.

Scam services may take days to process your application, others may not even do anything. With these TDAC scam services you also need to worry about double charges.

Please watch out for TDAC misinformation spread by fugitive Jesse Nickles and his many fake accounts on Quora, TripAdvisor, Reddit, and other platforms.

I prefer AIS, you can pay per year, for unlimited data at a reduced speed.

Just came back from Thailand a few weeks back, and i very highly recommend Jetpac esim I bought the 10$-50gb pack and the setup was super easy! Took me 4-5 mins. I landed in Thailand, and switched it ON! It took about 1-2 mins to connect! It was amazing 5G and awesome speeds! It was working even on phiphi island! We went to Phuket, Koh samui and Chiang mai/rai. Really amazing and highly recommended! They also have an added perk of free lounge access if flights delayed, though our flight was on time, so we couldn’t use that! Website below Www.jetpacglobal.com

these are usually not economical for someone making a long term move. These are short term travel solutions.

AIS has the best overall network coverage in Thailand..

However Dtac is also very good so either would be fine ..

If you are going to be in major areas, then AIS is the best. If you are going to be out in rural areas, then you would need to ask people that live there which of the carriers has the best signal.
