WhatsApp is reportedly testing its free voice calling feature through a limited number of people in India, possibly having sped up this launch to meet Hike’s challenge. But there’s not much reason for the former to worry about seeing as its second largest user base resides on these shores, while the latter is still trying to catch up to it. The free voice calling function appears to be available on invite-only basis at present. What this means is that you have to get a call through WhatsApp from someone who already has it. The release has been restricted to Android users for now and is reported to be accessible through the newest version 2.11.508 of the messenger app. The software update is not available through Google Play Store, but can be downloaded as an APK file via the official WhatsApp website section for Android. The news and images were picked up by GSMArena through a Reddit member dubbed pradnesh07 who was able to use it on a Nexus 5 smartphone running on Android 5.0 Lollipop. According to the tipster on Reddit, some people started seeing the VoIP feature merely after picking up a voice call made through WhatsApp and then restarting. But some folks may have to reinstall the application before being able to enjoy free voice calling. The invite-based launch makes it clear that things are being taken slowly.
