Call forwarding is a feature provided by your network carrier. If you’re having trouble setting up call forwarding directly from the CaptionCall app, it may be because your carrier has restricted access to enable it.

You can try toggling on call forwarding either directly from your phone’s device settings or by manually dialing your carrier-specific star code.

How to set up call forwarding from your device settings

For Apple devices:

Open the Settings app.


Tap Phone


Tap Call Forwarding


Toggle Call Forwarding on (toggle off to disable Call Forwarding)


Tap Forward To


Enter your CaptionCall number

For Android devices:

Open the Phone app


Tap the three dots at the top right corner


Tap Settings


Tap Calls (or Supplementary services)


Tap Call Forwarding


Tap Always Forward (recommended)


Enter your CaptionCall number

If you receive an error or there is no option for call forwarding, then your carrier plan may not support call forwarding. Please contact your cellular provider for details on adding call forwarding to your plan.
