Viber
Viber makes connecting with the world easier. An app that syncs with contact lists stored in android device, Viber is sure download for free calling. HD sound quality and an option of video calling puts Viber on a ‘must download’ list for free calling.
Skype
While other apps sync with the available contact list in the android device, we love Skype because it lets us connect with those who are on our skype list along with our existing contact list people. However, the reason we have put Skype at the end is, Skype does allow calling those who doesnt have a skype ID but at a minimal price. It’s free till the call happens between two skype ID owners.
