I've got a 9650 and I loaded skype mobile onto it. I have a skype account which is US unlimited monthly pay account. I also have an online number for it. When I dial my online number from another phone, my skype mobile never sees an incoming call.
I tried to call my number and see if skype on my laptop receives the call and it does. so, clearly skype mobile is deciding not to receive calls. I have the options set to receive calls from "anyone", so... any ideas?
Try to un-install the application then re-install Skype. Follow the steps below to un-install.
