JustCall FAQ

Since JustCall is a cloud based phone system, it’s not entirely dependent on your Internet connection. You can use your mobile phone number as one of your forwarding numbers, so even if your internet connection is lost, your calls can still be received on your cell phone. Alternatively, you can run the JustCall app (iOS & Android) on your mobile phone’s internet connection. Note: Without an Internet connection you can only receive calls on your forwarding number.
