Tell cellular data from Wi-Fi
Which of the two your phone is using, and which one spends money.
Wi-Fi comes from the box in your home and costs nothing extra. Cellular data comes from a tower and spends your monthly allowance.
The phone uses Wi-Fi whenever it can, and switches to data once you leave the house.
Key points
- Wi-Fi comes from your own box and costs nothing extra
- Cellular data comes from a tower and spends your allowance
What to remember
- One switch tells apps to wait for Wi-Fi before downloading.
- At home, Wi-Fi. Out of the house, the allowance.
Try this
Look at the top of your phone. A fan of curves is Wi-Fi; bars beside 4G or 5G means data.
