What is an eSIM?

An eSIM, or embedded SIM, is a digital SIM built directly into your device, whether it’s a smartphone, tablet, smartwatch, or any other electronic gadget. You can register your eSIM and start using it immediately on your device, eliminating the hassle of swapping out physical SIM cards. Say goodbye to the worry of losing your SIM and the inconvenience of removing the SIM tray to switch cards!

Instead of switching out SIM cards, you can activate and use your eSIM by simply scanning a QR code. Once set up, your eSIM connects to your network just like a traditional SIM card. Thailand’s True-dtac eSIM service makes it easy to stay connected, especially if you’re frequently on the move.

It’s More Convenient! One eSIM can support up to 6 different numbers on a single device, compatible with all networks for both prepaid and postpaid plans. You can easily switch between numbers as needed, and even use it when traveling abroad. The eSIM is designed for convenience and flexibility, making it the ideal solution for your connectivity needs.
