What is an eSIM?
eSIM stands for Embedded Subscriber Identity Module. Unlike the traditional, removable plastic SIM card, an eSIM is a tiny, digital SIM chip embedded directly into your device. You can’t remove it physically, but you can reprogram it wirelessly to switch between mobile carriers or data plans in minutes.
How Does eSIM Work?
Think of an eSIM as a blank digital SIM. Instead of inserting a physical card, you simply scan a QR code provided by your carrier (like ours!), or manually enter activation details. Your device downloads the carrier’s profile, and voilà—you’re connected. One device can store multiple eSIM profiles, allowing you to switch between them easily from your settings.Is My Device Compatible?
