2ndLine is not an eSIM. It offers a different solution for obtaining a virtual phone number:
- 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.
- 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.
Additional Considerations:
- Porting a virtual number from 2ndLine to a real network and vice versa "is not possible".
- 2ndLine might not be the best solution if you need data access or prefer a traditional phone number associated with a specific network operator.
