Frequently Asked Questions

How does AI call screening work?

When someone not in your contacts calls, our AI assistant answers first. It asks why they're calling and screens out spam. Real callers get connected to you; robocalls and scammers don't.

Is my data private?

Yes. Calls and messages between Shield users are end-to-end encrypted. We can't read your messages or listen to your calls. Your personal information is never sold or shared.

Can I keep my existing number?

ShieldLine gives you a new private number. You keep your existing carrier number and use ShieldLine as a second line for when you want extra privacy.

How is this different from my carrier?

Unlike carrier numbers, ShieldLine can't be stolen via SIM swap attacks. Plus you get AI spam protection, encrypted calls, and it works anywhere with WiFi - no cell signal needed.

What type of number do I get?

You receive a real +1 US-based phone number that can call and text any US/Canada number.

Do I need a data plan?

ShieldLine works over WiFi or any internet connection. You don't need a cellular data plan - perfect for traveling or using on WiFi-only devices.

What happens if I cancel?

You can cancel anytime. There's a grace period to renew if you change your mind, but your number may be released if not renewed.
