Introduction
In 2025, video calls are part of everyday life—for work, study, business, and family. But not everyone has fast internet. In rural areas, developing countries, or crowded networks, people still deal with slow speeds, high ping, and weak connections.
Most apps like Zoom or Google Meet are built for stable networks. On weak connections, calls freeze, audio breaks, and video lags. That’s where low-bandwidth optimized video apps come in. They compress audio/video, adapt to bad networks, and keep calls running even on 2G or 3G speeds.
