Short answer
With a Thailand eSIM you skip the tourist-SIM counters at Suvarnabhumi and Phuket airports and get online as soon as you land. Thailand has some of the cheapest travel data in the world, so a generous plan or an unlimited day pass is usually worth it.

Coverage in Thailand
Thailand's networks are AIS, TrueMove H and dtac. Bangkok, Chiang Mai, Phuket, Krabi, Koh Samui and the main islands have fast 4G and 5G; each plan card shows its partner network.
Coverage is weaker in remote national parks and on some small islands, and can slow down at busy events such as full-moon parties.
How much data do you need?
- Bangkok, 4–5 days: 3–5 GB.
- Two weeks with Chiang Mai and the islands: 15–20 GB.
- Heavy social media and video: an unlimited day pass.
Travel tips
- Grab and Bolt are the main ride apps; in Bangkok the BTS and MRT are faster than taxis at rush hour.
- Ferry and island-hopping tickets are often digital, so keep data on at the pier.
- Combining Thailand with Malaysia, Singapore or Vietnam? A South-East Asia regional plan covers them with one eSIM.
Frequently asked questions
Does the eSIM work on Koh Phi Phi and Koh Samui?
Yes, the main tourist islands have coverage, though some remote beaches and small islands are weaker.
Is an eSIM cheaper than a tourist SIM at the airport?
Often it is similar or cheaper, and you don't spend time queuing or registering your passport.
Do I get a Thai number?
