Do I need a second phone number to make calls using an eSIM?
No, you don't need an additional phone number to make calls with an eSIM. Here's how it works:
With eSIMania's data plans, you can use popular VoIP apps like:
- FaceTime
- Skype
- Messenger
These apps use Voice over Internet Protocol (VoIP) technology, letting you make calls through your internet connection instead of cellular networks. Your contacts will still see your primary number.
