And it was a matter of survival, could one business get the same profit without tuning for such phenomenon?

The first global decision was to transform all working processes into online versions. Some people could do that while others couldn’t. And video calls became a crucial part of this process.

Immediately, plenty of workers and customers started discussing business issues in Zoom, Telegram, Facebook Messanger, WhatsApp, etc. And it surely helped the situation greatly. Now, even when most people work from offices, many business owners continue to use video messengers as a tool to communicate with customers or teams. Thanks to that, many adopted the hybrid version of a working process, where specialists can simply stay at home and create a public call to solve the task.

More than that, many people started to talk to their friends and family via such apps. It doesn’t mean they’ve just started communicating, it means, that they’ve received a new tool with new and better options.

The service has a free version. Before the pandemic, Zoom had free 40-minute videoconferences. For the period of the pandemic, this restriction was removed and made it possible to do online events for up to 5 hours for 2-50 people for free.

You can also pay $15 per month to organize a conference for 100 people or chat for more than five hours.


Viber is a VoIP phone system that works seamlessly across various platforms. It is available for free for everyone. Every user can call for free within the app or call abroad for a fair sum of money.

Facebook Messanger

Facebook Messenger is an exchanging service for instant messages, links, videos, pictures, and other information. It is directly linked to the Facebook website. This messenger is similar to many others, but it has its own characteristics, for example, it can send messages from the phone book, create a video chat app’s group chats, attach media files to messages, supports calls. At the same time, the correspondence can be spiced up with different stickers and voice messages. You can also see your opponent while talking via your camera.

Telegram is one of the quite popular messengers. It is already used by 500 million people all over the world. Its main purpose is not much different from other apps: it sends text, voice, video messages, as well as files. For now, it seems that Telegram doesn’t really differ from its competitors, but it has its UVP.
