Phones can feel when Wi-Fi is getting weaker, like a voice saying, 'I'm fading out.' Then they know it's time to find another connection. That other connection could be your phone’s mobile data, the one you use when you're on the go. Think of it like having two friends: one at home (Wi-Fi), and one outside with you (mobile data). When your home friend gets quiet, the one outside takes over so you can still talk clearly.
Examples
- Your phone switches from Wi-Fi to mobile data when you leave your house and the Wi-Fi connection starts fading out.
- When streaming a movie, your phone automatically switches to mobile data if the Wi-Fi signal becomes too weak or unstable.
- Your phone switches back to Wi-Fi as soon as it detects that the home network has a stronger signal.
