For personal safety
Giving someone your number is easy to do and impossible to undo. A 2nd Line number lets you swap numbers on a dating app, keep talking as long as you want to, and stop entirely if you change your mind, while your real number stays known only to people you trust.
Why it works
Share a line that is not connected to your SIM, your bank or your family.
Face ID, Touch ID or a PIN keeps the conversations private on your phone.
Block a number in a tap. The blocked list belongs to that line only.
Change the number or let it go when you no longer want it in use.
A mobile number is often enough to find social profiles, a workplace, sometimes an address. That is a lot to hand to someone you met an hour ago.
A separate number breaks that chain. The conversation can go well without it ever leading back to your personal accounts.
App lock means the messages are not visible to anyone who picks up your phone, including people who already know your passcode.
That matters when the reason for a second number is exactly the people closest to you.
Yes. Many people use a 2nd Line number so they can talk by call and text without giving out the number tied to their personal accounts.
Yes. The app can be locked with Face ID, Touch ID or a PIN, so the messages are not visible to anyone holding your phone.
Block the number on that line, or change or release the number entirely. Your personal number is never affected.
Send and receive international texts & calls instantly without ever needing a new SIM card.
