Phones use signals from space and nearby towers to know where you are. Imagine your phone is like a detective that listens to clues from satellites and cell towers. When you open a map, it asks the sky and the nearest buildings for help, and poof!, it knows exactly where you are, even if you didn’t tell it.
Examples
- You receive a notification about a nearby restaurant before you opened your map, your phone already knew where you were.
- Your phone switches to a local news channel automatically, just by knowing which city you're in.
