Phones are like smart kids who know when to switch between two different ways of getting a message across, one is like talking in the same room (Wi-Fi), and the other is like sending letters through the mail (mobile data). If the Wi-Fi becomes slow or breaks, your phone checks if the mobile network is faster and switches over automatically. It's like picking up a new pencil when yours runs out of ink.
Examples
- A phone switches from Wi-Fi at home to mobile data when you walk out of the house.
- Your phone changes networks so you don’t lose your connection while watching a movie on the bus.
- When you’re on a Zoom call, your phone can switch between Wi-Fi and mobile networks without you noticing.
