I can not seem to call forward to another cell phone number. I have tried *72 but I seem to get a busy signal or hand up before I can enter a 10 digit phone. Does anyone out there know how to do this feature?
You have to dial *72 (plus the number you want to forward the calls to) and then place the call. It does not work like it would on a landline phone (dial *72, wait for the tone and then dial the number to forward to). This info (and much more) is available on your iPhone by going into Safari and looking at the User Guide in the bookmarks.
Thank you for excellent information kaebfly. Below I have also included the instructions for deactivating Calling Forwarding:
