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).
- ●The national average comfortably covers maps, messaging and streaming ; in Thailand the real difference is island and national-park coverage, not speed.
- ●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.

The dependable window runs from November to February: dry, warm rather than punishing, and workable seas on both coasts. March and April are the hottest weeks of the year, and the summer monsoon's severity depends entirely on which coast you picked.
Two coasts, two monsoons
The Andaman coast and the Gulf of Thailand do not get their rain in the same months, and the offset runs to several weeks. A trip that lands in the wet season on one side will often find sun by simply crossing to the other, which a pre-booked single-island itinerary rules out.
The burning season in the north
Late winter and early spring bring agricultural burning across the northern provinces, and the haze settles into the valleys for weeks. Chiang Mai and Chiang Rai can post some of the worst air quality in the world during that stretch, which no weather forecast shows you.
Check your own exemption length
The visa-free allowance has been changed more than once in recent years, and the figure circulating in travel forums is not always the one the ministry's own checker returns. Run your passport through the official e-visa checker before booking an onward flight, because overstaying is fined per day on departure.
Domestic legs eat days
The islands are a long way from Bangkok, and the real cost of a southern beach is a flight plus a ferry plus a transfer, usually with a fixed sailing schedule at the end. Two island stops in one week looks fine on a map and spends most of it in transit.
Iconic sites and coverage
Grand Palace
The former royal residence at the heart of Bangkok holds Wat Phra Kaew and its Emerald Buddha, still the most sacred shrine in the country. Admission is charged, the dress code is enforced at the gate rather than politely suggested, and the crowd arrives by late morning.
Wat Pho
Next door to the Grand Palace, Wat Pho keeps a reclining Buddha tens of metres long and the country's oldest traditional massage school, which still teaches and still treats. It is quieter and more lived-in than its famous neighbour, for a far smaller ticket.
Ayutthaya Historical Park
Capital of the kingdom until its destruction in the eighteenth century, Ayutthaya leaves dozens of brick temples spread across a river island, listed as world heritage. It is best covered by bicycle, and the ordinary train from Bangkok gets there faster than most organised day tours.
Chiang Mai Old City
A square of moat and wall encloses the old city, its many wooden temples and its night markets, in a place that does not run at Bangkok's pace. It is the usual base for the north and the starting point for trekking in the hills.
Railay Beach
Railay can only be reached by boat: limestone cliffs cut the peninsula off from the road, which is exactly what made it a climbing destination. Longtail boats stop running when the sea gets up, and that dependence on the crossing shapes every plan made there.
Khao Sok National Park
Old-growth rainforest, karst towers and a reservoir dotted with floating raft houses: Khao Sok is mostly seen from the water. Signal drops as soon as you leave the entrance village, and nights on the lake run without continuous power.
Similan Islands
A granite archipelago in clear water, the Similans form a national park that closes for several months each monsoon so the reefs can recover. Diving is the reason to come, and everything is arranged from the mainland, as a long day trip or a liveaboard.
Ko Tao
The smallest of the Gulf islands lives on diving, for a simple reason: the sites are shallow and sheltered, which makes it one of the places in the world that issues the most entry-level certifications. Signal holds on the main beaches and gives up on the inland tracks.

Price per GB in Thailand: what our data shows
According to the Datadopt Observatory, the lowest price per GB recorded in Thailand comes down to 0.05 €/GB, across a sample of 2,779 fixed-volume offers retained for the measurement. That floor is reached on large data bundles : a 5 GB plan over 30 days costs noticeably more per GB. The real differentiator is still the depth of the offer : the more plans compete, the easier it is to find the duration and data volume that fit your trip.

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.
How much does an eSIM cost in Thailand, and is it cheap?
According to the Datadopt Observatory, the lowest price per GB recorded in Thailand comes down to 0.05 €/GB, across a sample of 2,779 fixed-volume offers retained for the measurement.

Thailand is 76% cheaper than the Asia regional average (0.21 €/GB). In our global ranking of well-covered eSIM markets, Thailand sits at position 2 of 215 by price per GB (1 = cheapest).
