If you are forwarding an online number to a mobile phone it has to be covered by your subscription or it will cost you credit. If you have a skype app on your mobile it should ring when someone calls you on skype. Example the other day I was away from my computer, and a friend called me from asia. My cell phone rang as I was logged on to skype through my cell phone. If I am at the computer both ring, and I can answer either one I want to. You cannot forward to a phone w/o an online number.
