1. What Is an eSIM & Why Should You Get One?

An eSIM, short for “embedded SIM”, is a digital SIM card that is embedded directly into a device, eliminating the need for a physical SIM card. This technology is becoming increasingly popular due to its convenience and flexibility.

Why should you get one? That’s easy. Because it’s software-based, the physical card is no longer required and that means you won’t have to change out your current SIM card. Another benefit is that with some eSIMs, you don’t have to visit a pick-up booth; you’ll receive the scannable eSIM QR code instantly after booking.
