🇹🇭 Southeast Asia
Compare the best Thailand eSIM options for Bangkok, Chiang Mai, Phuket, Koh Samui, and island-hopping itineraries — find the right data size, hotspot support, and setup steps before you fly.
Quick recommendation
Start with a plan that covers your daily maps, messaging, and transport apps. If you expect to work, hotspot, or stream, choose more data upfront.
A 5–10 GB plan covers most one- to two-week Thailand trips. Bangkok is data-intensive: Grab (the dominant ride app — Uber is not widely available in Thailand) needs a live connection for every ride, Google Maps runs between neighborhoods, and Google Translate helps with menus and street signs. Chiang Mai is lower-usage but coworking café Wi-Fi can be unreliable, so having a mobile backup matters. Beach islands — Koh Samui, Koh Phangan, Phuket — have generally decent 4G in resort and town areas; signal can drop in jungle, rural, and boat transit zones. Download offline maps before heading to any island.
The safest choice is usually the plan that fits your itinerary, your data habits, and whether you need hotspot support.

Thailand on AIS network
A tourist eSIM from AIS, Thailand's largest carrier — designed for visitors without requiring a Thai phone number.
Travelers to Thailand who want a plan from the dominant local carrier.
Use your trip length, daily usage, and hotspot needs to narrow the list. The right plan is usually the one that matches your travel pattern without leaving too much unused data.
Choose the plan that gives you enough data for maps, translation, and a few longer days without forcing you to top up immediately.
Look for a larger data allowance or an unlimited-style plan if you work on the go, stream, or share data with another device.
Smaller plans are often enough for short city breaks, as long as the validity period covers the whole trip.
Check tethering support before buying so you are not stuck after landing if you need to connect a laptop or tablet.
Thailand trips vary in data demand by destination. Bangkok is the highest-usage city on most itineraries: Grab for every ride, Google Maps navigating between Sukhumvit, the Old City, and the riverside, and Google Translate for menus and street stalls add up to roughly 500 MB–1 GB per active city day. Chiang Mai is a little lower — it is more walkable — but coworking spaces and cafés do not always have reliable Wi-Fi, so a mobile backup matters. Beach islands (Phuket, Koh Samui, Koh Phangan) have solid 4G in town and resort zones; coverage weakens in jungle areas and on ferries between islands. Plan for 500 MB–1 GB per active city day and less on beach or travel days. Digital nomads planning to work remotely should budget for hotspot use and go to 10 GB or more.
Light usage
1-3 GB
Good for short trips, light maps, and messaging.
Moderate usage
5-10 GB
Best for most travelers who use maps and social apps daily.
Heavy usage
10 GB+
Useful if you hotspot, stream, or stay connected all day.
Hotspot support varies by provider and plan — confirm before buying if you need to tether a laptop or tablet. Airalo, Nomad, and Saily generally support hotspot on their Thailand plans. eSIM2Fly runs on the AIS network; check their plan page for current tethering terms.

There are no regulatory restrictions on activating eSIMs in Thailand.

Enable Data Roaming under the eSIM line once it is active or the connection will not establish.
To check eSIM support on iPhone, go to Settings → General → About and look for an EID number. On Android, go to Settings → About phone → SIM status, or dial *#06# — an EID confirms eSIM hardware is present. If no EID appears, the device does not support eSIM.
