We tried six popular apps that allow people to make calls using different conditions and in different kind of usage conditions.

WhatsApp is the most notable new entrant to offer internet calling but is it the best considering voice calling has been a feature on numerous apps before it?

There are plenty of options for users so that they can make calls for free on a Wi-Fi network or a 3G network. If it brings all of its features - including video calling and screen sharing - for free and lets you use it across multiple devices, it could offer some genuine competition to WhatsApp and Viber.By Sahil Mohan Gupta: We live in a world that is fast moving towards voice calling via the internet through various VoIP apps. Without knowing exactly what the BBM app will be like on iOS or Android, it's difficult to know how well it will stack up against the others. If it can sort out the issues then it could be a superb app, regardless of which phone you choose. While Viber has the benefit of being available on multiple devices across different platforms, it's let down by very buggy software. If you switch to a new phone, you'll have to perform the setup fresh each time, and you won't be able to see older conversations.Īll three services offer the same core functionality of sending text and photo messages for free over an Internet connection. If you use more than one phone at once then you'll have to switch to your 'main' phone to use WhatsApp. That means you can't use it on more than one device, and there's no desktop software you can use either. Unlike Viber, WhatsApp must be linked to your phone with your SIM card and phone number, acting more like the built-in SMS tool than an IM client. WhatsApp lets you send photos, videos, audio, map locations but you can't video call.
