What are the best options for purchasing an e-SIM with a 90-day plan in Thailand?

Question

Hello!  Arriving on Friday for 3 months.  We will probably purchase e-sims at the airport.  Do you know if any of the major carriers offer 90 day plans? We are mainly concerned about data and not too much with phone calls.  Also, will it work with an Apple watch and is something you need to pay extra for?  Thanks!

For expats arriving in Thailand, various carriers offer e-SIM options with 90-day plans focused on data. AIS, TRUE, and DTAC are popular choices, with TRUE providing plans like 100 minutes and 40GB for approximately 299 baht monthly. It's recommended to buy SIMs outside of the airport, as they tend to be cheaper at places like 7/11 or directly from the service providers in malls. All major carriers support Apple Watch, often requiring an additional fee. Finnmobile is also an option for unlimited data delivered to your hotel.

Don’t buy at the airport

You can get a Finnmobile SIM delivered for free to your hotel, just order a few days in advance. Cheap and unlimited data if you toggle to 20mbps speed limit. I've been using it for 2 years without issues.

They sell them at the airport but a little more expensive. Better to buy from a 7/11 or better yet from the company direct in any mall. I used to pay around 7/800 baht for a month unlimited at the airport but now have dtac (true network) eSIM for 1200 unlimited for a year. eSIM is also available for your Apple Watch 👍
