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 $0.68 today — 24% 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 4,853.

That is 45% below the $1.23 a gigabyte typically costs across the 229 destinations we track — only 9 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 4,853 plans for Thailand from 32 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?

AIS, dtac, TrueMove and TrueMove H are the local networks named across a broad field of travel eSIM brands. AbestESIM, iroamly, Roamix, MicroESIM, AirHub and Stellar eSIM have particularly deep catalogues for Thailand, but the breadth of the market makes the brand list less useful as a filter. Since most major providers sell Thailand, the practical differences are the amount of data, the plan’s duration, expiry rules, top-up options and which network is named. A familiar provider may still offer a poor fit for a short visit or heavier use.

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

AIS, dtac, TrueMove and TrueMove H are the operators named in travel-eSIM listings for Thailand. A travel eSIM has no separate network of its own, and you usually do not choose the Thai operator after purchasing it. Instead, which operator you end up on follows from the list published by the provider you select, making that detail relevant when comparing eSIMs. The listed operators show what providers disclose about their arrangements, not a ranking of signal strength, rural reach or overall network performance.

Are there any free data eSIM plans available for Thailand?

A zero-cost data option is available for Thailand, but it is a small trial rather than a travel allowance. It usually requires registering with the provider and may be limited to one redemption per customer. That makes it useful for sending a message or getting basic access when you arrive, not for relying on throughout a holiday. Thailand is well covered by eSIM sellers, so this is an exception within a largely paid market, not the usual type of plan.

Are there any unlimited data eSIM plans available for Thailand?

Several major providers list unlimited options for Thailand, but the label refers to continued access rather than unrestricted speed. Once a plan’s fast-data allowance has been used, the connection is throttled for the relevant period: video may become difficult and maps can load slowly, even though messaging usually continues. Offers differ in how much data runs at full speed and when that allowance refreshes, so those details matter more than the headline label when comparing them.

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.
