Smartphones are like tiny helpers that listen to both WiFi and cell phone signals. If one of them is getting weaker, the smartphone switches to the stronger one so you can keep using your apps without interruption.
Examples
- You're watching a video on WiFi in your living room, but when you go to the kitchen, your phone switches to mobile data automatically.
- Your phone stays connected to WiFi while you’re at home, but as soon as you walk out of range, it switches back to mobile data.
- When your WiFi starts lagging during a Zoom call, your smartphone quickly switches to mobile data without you noticing.
