Call Plus Apps has been introduced to make free calls to mobile phones as well as landlines. This app will work in Androids and Apple smart phones. People can now talk to their friends and relatives in US, Mexico, China, Brazil, Pakistan and other foreign countries by downloading this app in their mobiles. Not only to foreign countries, it is also possible to talk to Indian numbers. However, it is not possible to use within India. Already mobile users are familiar with Viber, which provides the same facility. With Viber Apps, both persons engaged in the talk must have the app in their mobile. However, with Call Plus Apps, there is no such need.
