Call forwarding Call forwarding allows you to forward your incoming calls to another number. You can set it up to forward all your calls immediately. Or, you can set it up to forward if you don’t answer the call, if your phone is turned off, or if you’re out of signal range. Be aware of the following when using call forwarding: You can’t forward calls to international numbers. You can only forward calls to 10- or 11-digit numbers. Forwarding while roaming depends on the host country’s network capabilities. For steps on call forwarding: Go to the Devices page. Select your phone. Scroll down to the How Tos section and select Calling & Contacts. Select Block and manage calls for your device. Follow the steps for setting up call forwarding for your device.
