We all know about Skype these days and its very good, but there are a ew others out there now.
I recently bought a nokia n95 and its changed my phone bills for the better.
The best thing wih it and many other phones on the market is the built in wifi.
with it it opens a whole new field of calling options
I use a program which you can download for free called fring.
It gives access via wifi, gprs or 3g to msn, skype, voipstunt, googletalk and a few others.
its a great program giving you the ability to chat or call from your phone for free or for very little.
Saved the best for last, it’s another free program called truphone, with it you can call other truhone users or uk landlines for free using your wifi phone.
I use these two programs all the time now where there is wifi and these days there is loads of places where you can get free wifi.
So go google the programs and save yourself a fortune.
