eSIM for Thailand: prepaid data plans from $5.43
A travel eSIM for Thailand gives you working mobile data from the moment you land — no SIM swap, no roaming bill, and no queue at an airport kiosk. You buy your plan before you fly, receive a QR code by email, and go online as soon as you arrive. Everything is set up in advance, so your first taxi or map search just works.

Data from the airport to the islands
Whether you start in Bangkok, head north to Chiang Mai or fly out to Phuket, one eSIM keeps you connected across the trip. It covers the everyday things travellers actually need — maps, ride apps, translation, booking a room and sharing photos — without hunting for a shop or a local SIM on arrival.
Set it up before you fly
Install your eSIM at home while you still have Wi-Fi, then simply switch it on when you touch down. There is nothing physical to collect and no tiny card to swap, so you can keep your usual SIM in the phone for calls and texts and use the travel plan for data.
Keep your number and WhatsApp
Your existing number stays active in the background, so WhatsApp, iMessage and two-factor codes carry on as normal. The eSIM handles data only, which means you can message home and use your regular apps without changing accounts or telling anyone a new number.
FAQ
When should I activate my Thailand eSIM?
Install it before you leave home while you have Wi-Fi, but wait to switch on the data plan until you arrive. Most plans start counting from first use or first connection in the country, so activating on landing gives you the full validity.
Will my phone work with an eSIM in Thailand?
Most recent iPhones and many Android phones support eSIM. Check that your handset is eSIM-compatible and not network-locked before you buy. If it supports eSIM, it will connect the same way whether you are in a city or by the coast.
How much data will I need for a trip?
For maps, messaging and everyday browsing, a moderate allowance covers most trips. If you stream video, upload lots of photos or use your phone as a hotspot, choose a larger plan so you are not topping up mid-journey.
