Complete Guide to eSIM Transfer, Activation, and Compatible Devices

How Does eSIM Work? (Wie funktioniert eSIM?)

The fundamental process of Wie funktioniert eSIM involves:

1. Profile Download: When you subscribe to a carrier, you receive a QR code or activation code.
2. Profile Installation: Your device reads this code and downloads the carrier profile to the eSIM.
3. Profile Management: Through your device settings, you can activate, deactivate, or switch between multiple profiles.
4. Remote Updates: Carriers can push updates to your profile over the air, eliminating the need for physical replacements.

This streamlined process makes eSIM technology particularly valuable for travelers and those who frequently switch between carriers.
