Thailand eSIM
This page is for visitors coming to Thailand. Coverage across cities and major tourist areas is good, and an eSIM means you are online the moment you land instead of queueing for a SIM at the airport. A typical itinerary pairs Bangkok with either the islands or the north, and those two halves put very different demands on a mobile connection.

What happens when your GB runs out
A GB plan is a fixed amount of data. When it is used up, data on that eSIM stops and nothing is charged automatically, but you can top up the same eSIM without a new QR code, and check what is left any time from your order page.

How much data you actually need
About 1–2GB a day for maps, rides and photos. If you are island-hopping and uploading video every night, or sharing a hotspot with travel companions, budget above that so the allowance lasts the full trip.
When you land
The main airports are Suvarnabhumi (BKK), Don Mueang (DMK), Phuket (HKT), Chiang Mai (CNX) and Samui (USM). Turn the eSIM on as you land so you can order a ride in an app or check the airport rail link before you walk out of the terminal.
Where coverage changes
Bangkok and the provincial cities have wide 5G, including inside BTS and MRT stations. Outer islands, national parks and parts of the ferry crossings fall back to 4G or drop entirely, so download the map area and save your boat tickets to the phone before you leave the pier.
Cities travellers ask about
- Bangkok — City-wide coverage including BTS and MRT stations.
- Phuket — Solid on the main beaches; boats to outer islands vary.
- Chiang Mai — Good in town, weaker on the high mountain roads.
- Krabi — Fine in town and Ao Nang; offshore it drops in places.
Read it city by city: Bangkok, Phuket, Chiang Mai, Krabi, Pattaya, Koh Samui
Apps to install before you fly
- Grab or Bolt for rides
- ViaBus for live Bangkok bus tracking
- Google Maps with offline areas before park visits

FAQ
Do visitors need to register an eSIM in Thailand?+
Traveller plans are prepared to work as soon as you install the profile and switch the line on, so there is no counter visit with documents the way a traditional prepaid SIM purchase works. What you should do is install while you still have Wi-Fi and keep the order confirmation email, in case you need to contact the team later.
How is the signal on Koh Tao or Koh Phangan?+
Villages, piers and the main beaches are usually fine, but on the ferry crossing and in small bays shielded by hills the signal weakens or disappears for stretches. Save your boat ticket, your accommodation address and an offline map to the phone before you set out, so nothing depends on being online mid-crossing.
Can a Thailand plan continue into Laos or Cambodia?+
A single-country plan covers Thailand only; once you cross a border the phone attaches to a network outside the coverage area. If the itinerary spans several countries, choose an ASEAN or Asia regional plan that lists them all from the start, so you are not hunting for Wi-Fi to buy another plan at a border crossing.
When does a Thailand eSIM start counting days?+
Most plans here start when the phone first connects to a network at the destination, so you can install in advance at home and switch it on after landing. Each plan page states its own rule.
Do I have to remove my home SIM?+
No. The eSIM is a second line, so you keep your home number for SMS OTP. Turn off roaming data on the home line and set the eSIM as the data line.
