Why Do Phones Sometimes Work Through Walls But Not Others?

Imagine your phone is like a tiny radio. When it's near you, it sends messages clearly. But when it has to go through walls or floors, it’s like shouting across a noisy room, sometimes the message gets lost on the way. Some phones are louder (stronger signals) and can push through more noise, while others get muffled easily.
