The smart new way to connect: no physical SIM, no hassle, no borders.
Definition: What is an eSIM?
An eSIM (Embedded SIM) is a digital SIM card that's already integrated into your device. Unlike traditional physical SIMs, you don't need to insert anything: just scan a QR code to activate a data plan and start browsing. eSIMs work with a downloadable profile that allows you to change carriers or plans instantly and remotely.
How does an eSIM work?
An eSIM acts like a traditional SIM, but is integrated directly into your device's hardware. Once you purchase a data plan, you simply scan the QR code provided by the provider and the network profile is installed. In minutes, you'll be connected, without having to swap SIM cards, wait in lines, or rely on roaming.
eSIMs are compatible with modern smartphones such as iPhone XR and later, Samsung Galaxy S20+, Google Pixel, and many more.
