There are billions of mobile phones all communicating with each other sending wireless signals across the globe. How does each signal know where to go exactly, and how are they not intercepted by other signals?

Think of it like sound. If someone shouts loud enough, it doesn’t matter whether they point their mouth at you or not. If you are close enough, or the sound is loud enough, you will hear it because the sound waves bounce and travel in all directions.
The wireless signal doesn’t need to know where the device is, it just sends the signal out. The device knows where the signal is and is waiting to hear it’s name (number, ip address etc.)
