Smartphones know when to switch between Wi-Fi and mobile data by constantly checking which one is working better. Like a kid who switches from using their backpack to a lunchbox when one gets full, your phone checks if the Wi-Fi is strong enough or if the mobile data is faster. If it notices that one connection is slower or weaker than the other, it will switch automatically so you can keep streaming your favorite videos without interruptions.
Examples
- It stays on Wi-Fi in the kitchen but switches to mobile data when you walk outside.
- You’re watching a video, and suddenly it goes from smooth to pixelated, that means your phone is switching connections.
