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.
