Buying credit entitles you to 120 "Freedays". This means you can call, for a period of 120 days (unless stated otherwise), all destinations marked as "Free" for free! When you have run out of Freedays, you can call these destinations at a minimal rate.

The other condition is maximum 300 minutes per week of free pc to phone calls, measured over the last 7 days. If limit is exceeded, a minimal rate is charged.

If you deposit Euro 10, this works out to Euro 0.083 a day to make free calls to 32 destinations. Or work out the charge per minute and see if it isn't better than free way to make pc to phone calls.

The deal gets even sweeter if you consider that you can use your credit to make calls to non-free destinations. Moreover you don't have to earn free minutes here which costs you internet service charges if nothing else. Add up all the factors and draw your own conclusions.

(Number of free countries and freedays is correct at the time of updating this page (Nov. 14, 2006). These and other terms and conditions may be altered anytime by the VoIP providers so please refer to the site for the latest info.)
