Best eSIM for Thailand

Thailand is one of the easiest destinations for eSIMs — AIS, TrueMove and dtac all have strong nationwide coverage and most travel-eSIM providers resell at least one of them. Pick on price and unlimited-vs-capped, not on coverage.

At a glance

Budget pick: Talisim — $9.40 for 10 GB / 30 days on TrueMove H and dtac. The cheapest plans route through Hong Kong; $11.08 gets you the “Avoids Hong Kong IP” version, which adds AIS
Close second, on AIS: Nomad Thailand — $10 on AIS and dtac
Best for multi-country SE Asia trips: Airalo — $11 for its Thailand plan on TrueMove H and AIS, plus Asialink for longer trips
Best for unlimited streaming: Holafly Thailand — from $27.50 for 7 days, but hotspot is capped at about 500 MB–1 GB a day
For travellers buying in EUR/GBP/JPY/BRL: GigSky — rare multi-currency checkout, sometimes complimentary data for eligible Visa cardholders

Prices we checked

10 GB of data for 30 days, from each provider’s own website on 17 October 2026.

Provider	Price	Networks
Talisim	$9.40	TrueMove H, dtac
Nomad	$10.00	AIS, dtac
Airalo	$11.00	TrueMove H, AIS

Holafly sells unlimited data instead: $27.50 for 7 days or $50.50 for 15 days.

Network notes

AIS has the deepest rural coverage and is usually the partner eSIM providers prefer. TrueMove H is comparable in major cities and tourist islands. Coverage on remote islands (Koh Lipe, parts of Koh Lanta) drops to slow 4G or none — no provider’s eSIM will save you there.

Practical connectivity tips

Install before landing. Suvarnabhumi and Don Mueang Wi-Fi works but is congested at peak arrival times.
Apps you’ll actually want online: Grab (rides + food), Bolt, Google Maps offline maps for islands, Klook for tickets, LINE for restaurant bookings.
Long ferry rides (Surat Thani → islands) often drop to no signal for 90+ minutes. Download maps and entertainment beforehand.
Border-hopping to Laos/Cambodia for visa runs? A regional plan or Dracotel’s persistent balance saves you rebuying.

Watch out for

4G/5G is excellent in Bangkok and major beaches but inconsistent on smaller islands.
Some hotel Wi-Fi captive portals charge per device — your eSIM is usually faster and cheaper.
SMS-based banking 2FA from your home country may not arrive if your home SIM is off. Switch to an app-based authenticator before you fly.
