Planning a trip to Thailand and wondering what is the best eSIM for Thailand in 2026? In this updated guide I compare the best Thailand eSIM plans based on price, network coverage, data allowance, Fair Use Policy and real travel value.

After comparing the latest eSIM plans for Thailand, my top recommendation is the DTAC Happy Tourist eSIM from SimOptions. It connects directly to the local DTAC network in Thailand, includes truly high speed unlimited data, comes with a Thai phone number for calls and SMS and starts from around ~$10 USD for 10 days.

I have traveled to Thailand more than 25 times and in total spent almost one full year exploring the country. From Bangkok and Chiang Mai to Phuket, Krabi, Koh Samui and remote national parks, reliable mobile data has always been essential for navigation, booking transport, ordering taxis and staying connected.

Everything that is 'Swiss made' has a rock-solid reputation. Now it turns out that Yesim, a new eSIM provider, is also Swiss Made. So we immediately started testing this eSIM service to see what it is like. Here are our experiences and review after using Yesim eSIMs.

Yesim is an eSIM provider from Switzerland. They offer eSIM for travelers and business purposes. They offer coverage in over 200 destinations. Yesim has a wide range of data plans.
