JioCall

If you want to make video calls that are both cheap and that are crystal clear, you might want to give Jio4GVoice a try. This application was formerly known as JioJoin, but only the name has changed, not the features.
 
Other features included in this app, besides voice and video calls, include group chat, file sharing, location sharing, doodles, stickers, a unified inbox for SMS and chat, an enhanced dialer option, and in-call share.
 
Users can send doodles and sticker while there are on the phone with another user, meaning that it’s one of the few apps out there that can perform this action. It’s important to know that this application is only available for Jio SIM and Jio Network users.
