An eSIM for Thailand gives you mobile data on local networks without swapping your SIM card. Choose a plan, and we email you a QR code within seconds of payment.
Install it over Wi-Fi before you travel. The plan starts when your phone first connects to a network in Thailand, and your usual number stays active alongside it for calls and texts.
Running low? Top up the same eSIM from the top-up page — there is nothing to reinstall.

How it works
Three steps, no app and no account. Your eSIM arrives by email as a QR code.
Pick your destination and compare data, validity and price on one screen. Pay by card or with PayPal.
Scan the QR code we email you within seconds of payment. Install it on Wi-Fi before you fly, then turn on data roaming for the eSIM when you land.
Why eSIM Net?
No contracts, no store visits, no waiting. Just data that works where you are going.
Questions
An eSIM is a digital SIM built into your phone. It downloads a mobile data plan by QR code, so you can use local networks in Thailand without buying or inserting a physical SIM card.
Install it the day before you travel or just before departure, while you still have Wi-Fi at home. The plan's validity does not start until your phone connects to a supported network in Thailand.
Your plan starts when your phone first connects at your destination. Running low? Top up the same eSIM in a minute.
Regional and worldwide plans cover whole continents on a single profile, so a multi-country trip does not mean multiple purchases.
Your QR code is emailed the moment payment clears — not hours later, and not once you have already landed.
Install at home on Wi-Fi and the plan waits. Validity begins at your destination, not at the checkout.

Open your phone's cellular settings, choose the eSIM for mobile data and turn on data roaming for it. Your phone then connects to a supported local network automatically.
Most recent smartphones do, including iPhone XR and newer, Google Pixel 3 and newer, and Samsung Galaxy S20 and newer. Your phone must also be unlocked. Dial *#06# — if an EID number appears, your phone supports eSIM.
Yes. Top up the same eSIM from the top-up page using the ICCID from your delivery email. There is no new QR code to scan and nothing to reinstall.
