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!
TLDR : Answer Summary
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.
