Looking for cheap international calling rates on your Berry? We might have the solution for you.
Raketu is offering low international rates through a browser-based app for your BlackBerry.
To calculate calling rates, you can use their handy rates tool. I fiddled around with it a bit and found out that I can call a land-line in Chile for 2 cents/min... Or a land-line in Belgium for 1 cent/min. Not bad. Rates do jump up though when you call a cellular line. The same call to a cell in Chile would run you 20 cents/min, and for Belgium 22 cents/min.
Why Chile and Belgium? I don't know. However I do know you should check this out to see if you'd benefit.
