The eSIM is a digital version of the traditional SIM card. Instead of inserting a physical card into your phone, the data is stored directly on a microchip embedded in the device.
This allows you to activate a mobile data plan from anywhere by scanning a QR code or through an app. It's that simple. No waiting, no shipping, no hassle.
Why should you use an eSIM?
- Instant activation: Receive the code in your email and use it immediately.
- International coverage: Regional or global plans that work in multiple countries.
- More than one line on the same phone: Switch between your regular line and your travel line.
- Security: It can't be lost or broken, as it's integrated.
- Savings: Avoid expensive roaming and no need to rent routers.
- Sustainability: Zero plastic, zero waste.
What devices are compatible?
Nowadays, most mid-range and high-end phones already include eSIM compatibility, especially brands like Apple, Samsung, Google Pixel, Xiaomi, and more.
