Are you on the WhatsApp team or on the call team?
Currently, WhatsApp has become one of the most sought after alternatives for communication by people, both personally and professionally.
The application integrates several functions besides sending messages, such as sharing images and videos, gifs, files, and even the feature of calls and video calls, making it possible, for example, that you talk to a friend or family member who is in another country more easily. In addition, it is free and available on several platforms.
However, a disadvantage is the decrease in interactions with people, since most of them currently prefer to send text messages instead of making calls. As well, there may be some risks with the security of your information, in case of data leakage.
