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.

What eSIM data costs in Thailand

A gigabyte of data on a Thailand eSIM typically costs $0.75 today — 17% 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 9,341.

That is 54% below the $1.62 a gigabyte typically costs across the 229 destinations we track — only 17 of them come in lower, which puts Thailand among the cheapest places in the world to buy mobile data as a visitor. The move is recent: the figure went up 15% in September 2026 alone.

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?

AIS, dtac, TrueMove and TrueMove H are the local operators named behind the travel eSIM offers, so the many brand names do not necessarily mean separate networks. The deeper Thailand catalogues include RedEx eSIM, AbestESIM, iroamly, Roamix, MicroESIM and AirHub, alongside a broad field of other providers. The useful choice is therefore less about finding a brand that works and more about sorting package size, validity and what happens once the allowance is used. Check the terms for expiry, renewal or top-up options, as similar-looking prepaid offers can behave quite differently.

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

AIS and dtac are among the stated networks available across Thailand, alongside TrueMove and TrueMove H. This is a genuine choice of network access rather than a market where every eSIM lands on the same operator: a multi-network eSIM can switch between its listed operators when one is weaker, while a single-network option cannot. Check the network list against your route, and treat Roamix’s broader stated reach as a useful distinction when comparing otherwise similar tiles.
