My parents are in Europe and just called me using a free smartphone app called Viber.  It lets you make free calls to any user anywhere in the world over a WiFi or cellular signal.  Now I know many of you are saying, BFD, there are lots of apps that do that.  What is amazing about this one is the clarity of the call.  The connection was better than a landline connection.  I always complain when my mom calls me from her cellphone as I cannot hear half of what she says, yet when talking on this app not only is it free, but the clarity is just amazing. (no I don't have a connection to the company and don't get compensated for this)

Undoubtedly brought to you by the NSA for EVERYONE'S listening pleasure!

 

so much tinfoil..  so little time

Because it's on wifi is why the clarity is great

tango is so much  better

Orrrrr.... Tmobile free calling over wifi.

 

Also, wait for blackberry messenger to go cross platform in a few. Although I was impressed with facetime.

tango is so much  better

 

This.  I use Tango.

Or just use an Android phone and you Google hangouts...I've been doing free video calls on Talk/hangouts for years...WiFi-4g...free regardless

 

Edit: I think it may even be available for iPhone users also.
