iPhone call diversion

For 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.
