Smartphones are like people who know when to change clothes. If your phone is connected to Wi-Fi, it uses that connection to load things like videos and messages. But if the Wi-Fi becomes slow or stops working, the phone checks if its mobile data (like 4G or 5G) is better and switches automatically, just like changing from a sweater to a jacket when it gets cold.
Examples
- Your phone switches from Wi-Fi to mobile data when you leave your house and the internet gets slow.
- You're watching a video on Wi-Fi at home, but as you walk outside, your phone automatically uses mobile data instead.
- Smartphones switch connections like you switching between a radio and your phone's music app, seamless and automatic.
