New Delhi: A big problem with most smartphone apps is that they offer free voice calls when the person at the other end is using the same app.
Call+ app allows you to make free calls to landline and mobile phones alike -- without the need of both parties having the app installed. The app lets calls to a whopping 85 countries and shows your existing phone number as the caller ID.
You can make unlimited free calls to anyone in the continental US and landlines in Mexico, China and Brazil; however, if you want to call a different country, you have two options. You can buy one day of unlimited-calling service for 99 cents, two days for $1.99 and a month for $19.99.
Call+ also allows users to complete various “partner” offers in exchange for days of service. For example, if you sign up for a trial with dating service Zoosk, you can earn seven days.
