Is it fast enough for video calls and streaming?

Yes — plans are unlimited with no throttling games, on 5G in urban areas and fast 4G across the tourist coast.

Does one eSIM cover several Asian countries?

A Thailand eSIM covers Thailand only. For multi-stop Asian itineraries, the Asia regional eSIM covers 32 countries on a single plan and hops networks automatically as you travel.

Will my eSIM work as soon as I land in Thailand?

Yes — install it at home on Wi-Fi before you fly, then switch the line on when you land. It joins a partner network in Thailand automatically, usually before you reach baggage claim. Your days only start counting at that first connection.

Do I keep my own number and WhatsApp in Thailand?

Yes. This is a data-only eSIM that runs alongside your home SIM. Your number stays active for calls and texts, and WhatsApp keeps working on your usual number the whole trip.

When do my days start counting?

Only when the eSIM first connects to a network in Thailand — not when you buy or install it. Buying ahead of your trip is completely safe.

Which phones work with a Thailand eSIM?

Most phones from 2018 onward: iPhone XS and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer, plus many recent Xiaomi, Oppo and Motorola models. Your phone must also be carrier-unlocked — check yours in 30 seconds on our compatibility page.

Good to know

Long-stay day rates make month-long Thailand trips surprisingly cheap per day — 30-day plans get the deepest discount.

The Thailand eSIM guide.

Thailand is a long-haul favourite where data does everything: Grab rides in Bangkok, boat schedules to the islands, translated menus, and video calls home from the beach. Thai networks are strong across the tourist map, with 5G in the cities.

How it works on the day

Install before the long flight, land at BKK or HKT already connected. Island-hopping? The plan reconnects automatically as you move between Phuket, Krabi and the Gulf islands.

Choosing your days

Two-week holidays hit the discounted band; month-long winter escapes get the lowest day rate of all.
