タイ向けおすすめeSIM

Thailand has by some distance the lowest price per gigabyte in our entire catalogue. The reason is competition: AIS, True and dtac have fought over tourist traffic for years, and that pushes down the travel eSIMs riding on those networks too.

It doesn't follow that the biggest bundle is the best buy. A 50 GB plan over 30 days has a superb price per GB, but almost nobody uses 50 GB in a two-week holiday. The calculator below the table works from the days you're actually travelling instead of the best theoretical number.

Two weeks of travel with Grab, maps, a translator and photos: 5 GB is enough. Uploading video or working on the road pushes it to 10 GB. Wi-Fi in Thai hostels and cafés is good and widespread — unlike several neighbouring countries, you can genuinely offload a lot onto it.

Install the eSIM at home before flying. Suvarnabhumi arrivals is lined with SIM card stands charging well above anything in the table above — they're selling convenience, not the best price.
