I've used Skype on and off for years. I maintain a yearly subscription (a bit less than $3 a month) just in case. Always had excellent voice quality. In fact, I used one of the first "Skype" Phones as my primary house line for the better part of 6 months several years back. So I'd say go for it, just be careful on the data, and if you are using PagePlus data to route the Skype call...forget it, as your per-minute cost skyrockets.
