TLDR : Answer Summary
The conversation highlights recommendations for the best eSIM options while traveling in Thailand, particularly in Koh Samui. Users suggest AIS for excellent coverage and reliability, noting personal experiences such as consistent 5G service. Others mention the convenience of converting physical SIMs to eSIMs at local stores. Additionally, there's advice on using physical SIM cards for better rates and ease of use compared to airport options.
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.

Get a physical Sim not at the airport for AIS. If you don’t have dual sim, do an eSIM for your home country provider and insert the Thai AIS for data, Line and WhatsApp use. I have this and for three years it works awesome. Can make monthly payments at any AIS store and I have left for two months, came back, paid worked fine.

A friend has a house in Hua Hin and he always uses Dtac. Can anyone recommend a sim card for Thailand and Vietnam?

I had a True SIM card, then converted it to an eSIM. There is an option in the app to convert it, but I couldn’t get it to work. I went to the True shop, and they did it in 5 minutes.

I got a AIS 5G esim at the airport. It's not dropped to 4G in a week so far.
