Thailand eSIM comparison
Choosing the right Thailand eSIM requires comparing the local carrier (AIS, DTAC/True Move H, or CAT), coverage for your specific itinerary including Bangkok, Chiang Mai, Phuket, and island destinations, data allowance, hotspot rules, validity, and current checkout terms. RoamMatch shows the comparison evidence and links to official provider pages for verification.
Identify the exact Thai carrier used by the plan. Compare AIS, DTAC/True Move H, and CAT coverage maps with your itinerary including Bangkok, Chiang Mai, Phuket, Koh Samui, Koh Phangan, and any rural or island routes.
Estimate usage for maps, rideshare (Grab), bookings, messaging, social media, and hotspot. Unlimited-style plans may include speed reductions after a daily or total threshold.
Match the plan length with your full stay. Verify whether validity starts at installation, first network connection, or manual activation.
Check whether tethering is allowed and whether a separate daily or total hotspot allowance applies. Island accommodation with weak Wi-Fi is common — hotspot support matters.
Confirm the phone supports eSIM, is carrier-unlocked, and supports Thai network bands. Regional variants of the same model can differ.
Install the eSIM before landing. Save the QR code and support contact offline — island Wi-Fi and airport connectivity are not always reliable for initial setup.
Compare the official carrier coverage maps with your specific Thailand itinerary. Bangkok and major tourist areas are typically well-covered. Island and rural coverage varies by carrier.

Coverage on Thai islands varies. AIS generally has the widest island coverage. Verify the exact carrier on your chosen plan's product page and compare with AIS and DTAC/True Move H coverage maps for Koh Samui, Koh Phangan, Koh Lanta, or other specific islands on your itinerary.
Many Thailand eSIMs work on major tourist islands, but coverage and speed vary by carrier, location, and time of day. Koh Phangan during Full Moon Party periods can have network congestion. Verify the carrier used by your plan and compare the carrier's island coverage map.
Hotspot is supported on many Thailand eSIM plans, but the rules vary. Some plans include unlimited hotspot; others cap it at a daily allowance (e.g. 500 MB/day). Verify on the exact product page before purchasing.
Use the matcher to compare supported providers for your specific Thailand itinerary, trip length, data needs, and hotspot requirements.
