Thailand eSIM: land online, skip the SIM queue

Touch down connected: the plans here run on dtac or True, or a four-country regional one, at one price with tax, and switch on when you land, beside your own number.

A Thailand eSIM is a data plan on the country's own networks: the cards here run on dtac or True, or a four-country regional network, and cost from US$4.88 with tax. Some plans add a Thai number, and your own number stays in the phone either way. If it does not work and cannot be fixed, you get a full refund.

Questions about eSIM in Thailand

Illustration: a traveller on a longtail boat in a limestone bay holds up a phone.

What is the best eSIM for Thailand?

The one you can check before you pay: which Thai network it runs on, the data and the days, whether it includes a Thai phone number, and the price in US dollars with tax. The plans here run on dtac or True, or a four-country regional one, cost from US$4.88 with tax, and are refunded in full if they do not work and cannot be fixed.

How does a Thailand eSIM work?

At home on Wi-Fi, scan the QR code and leave the line off. Once in Thailand, switch it on and set it as the mobile data line. Your usual SIM stays in the phone, so your own number keeps working on WhatsApp.

Do I need a Thailand SIM card at the airport?

No, if the eSIM is installed: you switch it on after landing, with nothing to collect at the airport. A SIM card bought in Thailand is registered with your passport at the point of sale and comes with a Thai number. Some plans include a Thai number, and each plan states before you pay what it includes; your own number stays in the phone either way.

Do I need a Thailand arrival card?

Most visitors do: the Thailand Digital Arrival Card, TDAC, is free on the official portal and filed within the 3 days before you arrive. Keep the confirmation on your phone, and have it ready with your passport at immigration.

Can I buy an eSIM for Thailand from this site?

Yes. Pick a plan on VietSIM, the same company's store for Vietnam and Asia: this site's buttons open the store's Thailand page, and the QR code appears right after payment.

What is Local SIM Thailand?

A site about getting online in Thailand, run by LuKas Holdings sp. z o.o. in Warsaw. It covers the Thai networks, the arrival card and the airports, and shows the eSIM plans you buy on VietSIM, the same company's store for Vietnam and Asia.
