2ndLine is not an eSIM. It offers a different solution for obtaining a virtual phone number:

  1. 2ndLine: Utilizes "VoIP technology", allowing you to make and receive calls and texts using a "virtual number" provided by the app. This virtual number exists only within the 2ndLine ecosystem, not on a physical SIM card or eSIM.
  2. eSIM: Stands for "embedded SIM". It's a "digital chip embedded within your device" that can store multiple phone numbers and network operators, similar to a traditional SIM card but more compact and flexible.


Key points to remember:

  • No impact on existing lines: Using 2ndLine doesn't affect your existing SIM card or eSIM functionality.
  • Separate services: While both provide phone capabilities, they function differently and serve distinct purposes.
