iPhone call diversion

iPhone Call Forward PropertiesFor some strange reason, the call diversion features on the Apple iPhone are a bit lacking.

On Android, you’re able to easily set diversions based on “No answer”, “Busy” & “Not contactable”.

On the iPhone, the options aren’t there.  So you need to set the diversions the old fashioned way.  Using the GSM Feature Codes.

Function Dial

Activate divert all **21*<voicemail>#
Deactivate divert all ##21#
