Yes, what I really like is VOIP

With a Voip Account you can phone everyone in the world without spending a cent by directly call him to his pc or by calling to his phon for really a cent or less!!!

But, which is the best?

I have to say two things:

1- if you consider to phon your friends only to his computer (so not on his phone or cellular) then you must use Skype: it has the best audio quality and all the convesations are encrypted!

2- but if you want to call a phisicall phon line or a cellular, then Skype is one of the HIGHEST priced on the web (but it has one of the best audio and video quality service out there!). So trash it and use other companys:

VoipBuster

VoipCheap

Gizmo

VoipStunt

Messagenet

And other, but the above ones are the best of my exerience.

They all use their own software to make phone, but you could use other third party software like X3lite.

To use a VoiP service you need a CREDIT CARD, but if you are student and don't have any bank account, don't worry, I have the solution for you to have instantly a FREE CREDIT CARD!! Go HERE
