Instant Messaging (IM) voice-over-Internet Protocol apps for smartphones and tablets took the world by storm. Apps like Viber lets you text and call anyone, wherever they are in the world for free, as long as they have the same app on their phone or tablet. These messaging apps are usually free to download, and are starting to change the way we text. Messaging apps like Viber comes with “Delivered” and “Seen” features, letting you know if the person you sent a text to has already received and read your message.
