The idea is simple. This week my phone company network had a two day breakdown in my area. I could not make or receive calls. However since we now have smartphones there is almost always a possibility to connect to the Internet. So the idea is to connect to my phone account through the Internet instead. With an application on the phone I would then only need to turn on the Wifi and be able to make calls as usual. Even if the network is down. Also if you loose the phone, it gets stolen or you break it. It should then be possible to log in and make sms, calls and so on from a browser.
