No, people you call with your 2nd Phone Number won't automatically know it's you. Here's why:

  • Caller ID: When you make a call, the recipient will see the number you chose for your 2nd Phone Number, not your personal number. This keeps your privacy protected and lets you manage separate communication channels.

  • No Notifications: The 2nd Phone Number app doesn't send messages to your contacts letting them know you're using it. So, unless you tell them your 2nd Phone Number, they won't know your calls or texts come from there.

For additional privacy, you can:

  • Choose a different display name to appear when you call someone with your 2nd Phone Number.

While there's privacy by default, here are some things to keep in mind:

  • Transparency: It's always a good idea to be upfront about how you're contacting someone, especially in business or personal situations.

  • Local Laws: Some areas have regulations about caller ID and anonymity. Always follow local laws when using your 2nd Phone Number.

  • Spam Filters: Some recipients might have stricter settings that flag unknown numbers as spam.

By understanding these points, you can use your 2nd Phone Number effectively while maintaining privacy and respecting local regulations.
