All users have to do is log on to Facebook Chat in order to receive calls. To make calls, just head over to the Bobsled Facebook page to download the app, set up your mic/speakers for making and receiving calls and you’re good to go. Even though Bobsled is by T-Mobile, the app is not restricted to just T-Mobile users. But for now, it’s just limited to calls from computers to computers.
T-Mobile has plans to introduce mobile apps in the near future so users can stay in touch with their Facebook friends no matter where they are. Head over to the Bobsled by T-Mobile page for more details or head over to the Facebook page for Bobsled to download the app now.
