Perhaps you have already come across the term "eSIM" and wondered what an eSIM actually is. A further development of the classic SIM card, the eSIM is a chip permanently installed by the device manufacturer. The term eSIM is short for "embedded subscriber identity module" and describes a standardized procedure from 2015 for authenticating, storing and managing user data for the respective network operator.

Five plausible reasons that speak for an eSIM:

• Easier, more flexible, faster
• It's easier to switch networks. 
• Temporarily switch to another network - quite flexibly. 
• Use more than one SIM card. 
• eSIM also scores points with the environmentally conscious.
