Free Mobile Calls: Canada, USA Unlimited via Texting

Featured Site: http://www.boknow.com/

A Ottawa (Canada) based Company is offering the Free Calls via SMS / Text Messaging. Boknow.com is using VOIP technology to provide Americans and Canadians the free mobile calls, using the SMS.

How it works:

We have to send a SMS with our contact’s phone number to bOKnow.com, and, its like the famous Free Calling Site JaJah.com, bOK calls to both the parties — and its done, now you have free unlimited incoming calls!
The service is in beta and for the time being is for free for any phone numbers in the North America & Canada.

bOK now has a Facebook application too and could be integrated in Facebook for your friends to call for free in USA, CANADA.
