Which would u regard as the best free call application from the following lists
Tango
Giver
Skype
I have tried trio but as for me Tango is d best and an hidden treasure waiting to be discovered by smart phones users as u don't need to log in to use is all u need is to have the contact on your fone and the person u want to call will have it too then u can call each other using video call or voice call anywhere in the world for free so long the contact is on your fone and u have data plan for browsing. Give ur opinion too
