WhatsApp

The Meta-owned WhatsApp is an instant messaging and video calling app that comes at no cost. Its user base spans across over 180 countries, with a total of more than two billion individuals. WhatsApp is an uncomplicated, dependable platform that provides privacy, making it an excellent way to connect with loved ones. It even supports both desktop and mobile usage, and is successful even with weak internet connectivity. You do not have to pay any subscription fees to utilize this service.

WhatsApp provides secure messaging options globally. Your messages and calls to friends and family are encrypted seamlessly, and nobody beyond your chats can access them, not even WhatsApp. Communication is made even more straightforward as it requires no username or logins, only a phone number. The application works effortlessly with your phone's internet service, and you can view all the contacts that use WhatsApp, ready to message.

You can make free video and voice calls to up to eight individuals at once, with the calls encrypted for added security. End-to-end encrypted group chats allow easy communication and sharing of messages, photos, videos, and documents between desktop and mobile devices. You can choose what to share, and with whom to share through Status. Share your text, photos, videos, and GIF updates, which disappear after 24 hours. You can also share your location in individual or group chats, thus maintaining real-time connections.

Data costs may apply. Do ensure you contact your provider for details. Any feedback or queries can be given through WhatsApp's "Settings", moving to "Help," and proceeding to "Contact Us."
