Internet in Thailand: everything you need to know
Thailand shows an internet penetration rate of around 88% and a mobile infrastructure that is very accessible to travelers (source: ITU DataHub, 2024). 4G LTE covers every populated area (Bangkok, Phuket, Krabi, Chiang Mai, tourist islands), and 5G is rolling out in the main cities. A Thailand eSIM gets you onto this network the moment you land at Suvarnabhumi or Don Mueang, with no physical card swap.
- ●4G/5G coverage across every major tourist area (Bangkok, Phuket, Krabi, Koh Samui, Chiang Mai, Pattaya).
- ●Average mobile download speeds around 50 to 70 Mbps per Ookla (Q1 2025).
- ●Perfect for Grab (rideshare), Bolt, Google Maps, translation and booking apps.
- ●Stable connection on ferries between Koh Samui, Koh Phangan and Koh Tao thanks to coastal mobile coverage.

Frequently asked questions
Do eSIMs really work in Thailand?
Yes. The vast majority of international eSIMs connect to AIS or TrueMove H the moment you land at Bangkok or Phuket.
Do I need a VPN in Thailand?
No for everyday use. Some politically sensitive sites may be blocked locally, but Google, WhatsApp, Instagram, X and YouTube all work normally.
Can I keep my home phone number?
Yes. The Thailand eSIM installs alongside your main line. You keep your home number for SMS and calls while using the eSIM for mobile data.
What's the best eSIM for Bangkok or the islands?
Bangkok and Phuket have full 5G coverage; the main islands (Koh Samui, Koh Phangan, Koh Tao, Phi Phi) are covered in 4G. For a 1-2 week trip, a 5 to 10 GB plan is plenty.
Does the eSIM work on ferries and boats?
On coastal routes and between nearby islands (Koh Samui, Phi Phi, Krabi) coverage is generally maintained. On long ferries to Surat Thani the connection may drop for a few minutes on the open sea.
Can I share my connection with other devices?
Most Thailand eSIM plans allow hotspot tethering. The detail appears on each plan page on Datadopt.
