Why Do Phones Know When to Switch Between Wi-Fi and Mobile Data?

Imagine your phone is like a clever kid who knows when to use the school’s fast internet or their own mobile hotspot. If the Wi-Fi gets slow or drops, your phone quietly switches to mobile data, almost like magic! This smart change happens in the background so you can keep watching videos or playing games without interruptions.
