What Is QR Code eSIM Activation?

When you buy an eSIM plan, your provider sends you a QR code by email. Scanning it with your phone's camera automatically downloads and installs the eSIM profile — no manual configuration needed. It's faster, more secure, and more travel-friendly than any physical SIM.
