Cellity's taking it up a notch!
Cellity, my Hamburg-based investment, has just launched two new products: worldCALL and groupCALL. Now you can make international calls as well as conference calls, all using the application on your mobile device (all you need is a data connection). This allows you to save a bunch of money, especially if you already have a flat-rate data plan! If you haven't already, try it out. If you want to read some more about the product launch, take a look here.
