Imagine your phone is like a smart dog that knows which park to go to, the nearest one, or the one with more treats. If your home Wi-Fi is like a treat-filled park, and mobile data is another nearby park, your phone picks whichever has the best signal, just like the dog chooses the park with the most treats. That’s how it automatically switches networks without you even noticing.
Examples
- When your Wi-Fi goes out, it instantly switches to mobile data so you can still send messages.
