If your device is getting cellular service through an older CDMA network like Verizon or US Cellular, you can’t enable the service from your iPhone’s settings. You’ll need to use forwarding codes, also called carrier codes, to forward calls to another number on your iPhone.

The forwarding code varies on your carrier:

  • For Sprint users: Enable call forwarding using *72 followed by the phone number and turn it off by dialing *720.
  • For Verizon users: Dial *72 followed by your number and press Call to enable call forwarding. Disable it by calling *73.

There are also other codes that let you forward calls based on certain conditions. So, you will never miss any important phone calls, whether the call is left unanswered, your iPhone is unreachable due to poor network connections, or you are busy on another phone call.
