Which mobile networks you get in Thailand

AIS is named by most providers, so the underlying radio is effectively settled before an eSIM is chosen. The six listed networks—AIS, dtac, TrueMove, TrueMove H, TrueMove H / my by CAT, and dtac TriNet / LINE—look like a broad choice, but the legal entities behind them include Advanced Wireless Network Company Ltd., Total Access Communications Public Company Ltd., True Corporation, True Move H Universal Communication Company Ltd., CAT Telecom and DTAC TriNet Company Ltd. Separate brands can therefore sit under one parent. 5G is the fastest technology stated, but only a per-profile ceiling.

Where your data comes out in Thailand

None of the listed eSIMs breaks out in Thailand: most route traffic through Hong Kong, with others using Singapore or Indonesia, and one using the United States. That means a typical round trip to Thai services should be about 45ms, although the US route is estimated at roughly 225ms; this adds delay, not a limit on download speed. More importantly, your IP address will appear foreign, so a Thai banking app may reject it, while streaming services could show the breakout country’s catalogue.

Where providers break out, nearest country first. Estimated from distance, not measured.

What eSIM data costs in Thailand

A gigabyte of data on a Thailand eSIM typically costs $0.74 today — 18% less than the $0.90 it cost in December 2025, over which time the number of plans we compare for Thailand went from 1,936 to 14,030.

That is 61% below the $1.92 a gigabyte typically costs across the 234 destinations we track — only 37 of them come in lower, which puts Thailand among the cheapest places in the world to buy mobile data as a visitor. Competition is most of the story. We now compare 14,030 plans for Thailand from 70 providers, against 1,936 in December 2025.

Every figure here is the lower quartile of the plans in our catalogue that month — the cheaper end of what was actually on sale, rather than an average pulled up by a handful of premium plans.

Frequently Asked Questions about eSIMs for Thailand

How many travel eSIM brands (providers) are available for use in Thailand, and how many prepaid data plans are there?

Travel eSIM offers in Thailand resell access to local networks such as AIS and dtac; the brands themselves do not own those networks. Most major providers sell plans for the country, so the names alone do little to narrow the choice. The useful distinctions are how much data a plan includes, how long it remains valid and what happens when the allowance runs out. Check those terms against your likely usage: a familiar brand such as RedEx eSIM or AirHub is not automatically the right fit.

What are the mobile networks available for a travel eSIM in Thailand?

AIS, dtac, TrueMove and TrueMove H are the operators named in provider-published lists for Thailand. A travel eSIM has no network of its own; it roams onto a local operator, with the provider’s stated network list indicating which ones the plan may use. Buyers normally do not pick between these operators when connecting. Instead, the eSIM they choose determines the available operator options through the provider’s published details. That makes the underlying operator a product detail that can be known in advance, rather than an unexpected choice made by the phone.

Are there any free data eSIM plans available for Thailand?

Free data is available for Thailand, but only as a limited introductory allowance rather than a usable holiday plan. It is generally offered as a one-off trial after registration, so eligibility can depend on the provider and whether you have used its service before. That makes it handy for getting online shortly after arrival or testing compatibility, but most travellers will need a paid package for regular use.

Are there any unlimited data eSIM plans available for Thailand?

Unlimited options are available, and they are fairly common among providers selling Thailand eSIMs. The label is only a starting point: one package may restore its faster data each day, while another uses its allowance across the whole validity period. After that allowance is used, service continues at a reduced speed, which can make video frustrating and maps slow, even though messaging still works. Check the reset pattern and the post-threshold speed before choosing.

eSIM Providers for Thailand

Where you travel can make operator choice matter: AIS and dtac are both part of Thailand’s broad mix of networks sold through eSIMs. Providers collectively draw on most of the country’s networks, while only a few name a single operator, so some eSIMs can offer a fallback if one signal is weak; others may not. For a trip spanning several areas, check which operators each option says it uses before buying.
