TLDR : Answer Summary
A user shares their experience after receiving a DTV visa, asking for recommendations on reliable SIM cards for internet access in Thailand. Comments suggest options such as unlimited data SIMs for around 700 THB/month, and personal recommendations for True and DTAC, with users noting satisfactory experiences with their services.
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 agents.co.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've got a SIM from True, but I hear DTAC is better. True works fine. Top up in the app. Free data unlimited speed 1 month for 400-500THB per month, cheaper if they have promotions. Been using it for 2 years now and I'm very happy with it

I always ask for an unlimited data sim. Pay around 700b a month. Never let me down and Ive had different providers. Top up each month at the same shop
