TLDR : Answer Summary
The best option for getting a SIM card while visiting Thailand is to go for a non-tourist SIM, which allows for easy reactivation. Suggestions include using DTAC or AIS, as both have significant coverage and flexible plans. For example, it's possible to keep a non-tourist SIM active for as little as 10 Baht per month. Additionally, using an E-SIM is a great alternative that offers various plans and does not expire, making it ideal for frequent travelers.
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.

They seem to be cracking down on non tourists sims, and require a thai national card to buy them.

But I just went to a dtac/true store ask them for the 50baht esim (they will try selling you tourist packages just say no just esim only) it comes with 1 day unlimited then install the app and you will have heaps of packages to pick from all allot cheaper than the tourist package.

I got the 450 baht unlimited 10mbs data for 30days

Use an E-Sim that never expires. I use Roamless

Dtac ask for SIMPLE SIM set.... Any topup is valid for 1 year.... I have one for 20 years

Buy an esim off traveloka/klook/trip.com for a fraction of the cost. I get an esim for 2 dollars with 10gb for a month each time I’m

There. Obviously no phone number and only data but that’s enough for me. Never got sim cards for years while traveling ..

I would go with AIS. Best network.

But I guess you stay in tourist zones, so signal strength isn’t a thing.

Go shopping for promotions at the arrival hall. All major companies have a large booth there.

AIS

Dtac is great I use it and it works every tine

*113*30#... Dial this on dtac to extend a month for a few baht. Can be extended for months, no need to remember to top up..

Try a esim card for Asia if compatible with your cellphone.

airalo is way more expensive than local SIM cards
Madz ******
Download it before you go and "install" and follow the instructions whilst I'm at the airport

@Alain ********
it's just a simple app 👍🏽 I was worried it would be tricky, but really straightforward. You can buy days to months
Paul **********
Just get a non tourist SIM..download the app and top up 10 Baht a month to keep it active. 6 months at 10bht a month up up keeps it active.
Mike **********
@Paul *******
you don't have to top up every month. You can explicit extend the validity before leaving Thailand up to 1 year in the app or dialing an ussd code. It's only few baht for 30 days
Martyn ***********
@Mike *********
you mean that code I posted in the previous reply?? 🤔👍🤣
Mike **********
@Martyn **********
yes, but I use TRUE. There the code is *934*30# . Or with 180 instead 30 for 180 days
Martyn ***********
@Paul *******
with dtac you can call *113*30# and it extends a month for a few baht... You can extend for months at a time... No worries.
