Why does your phone sometimes use Wi-Fi and sometimes mobile data?
Both can connect you to the internet, but they work through very different types of networks.
In this episode, we'll explore how Wi-Fi connects your device to a local network, while mobile data uses cellular infrastructure designed for mobility. We'll also look at their radio technologies, coverage, speed, congestion, costs, and why your phone switches between them.

By the end, you'll understand what's really happening every time that tiny Wi-Fi or cellular icon appears on your phone.
