Evolution to 3G

When people first started using phones, they could only make calls and send text messages. This was known as 1G. Later on, a new type of phone was created that could do more things like take pictures and connect to the internet. This was called 2G.

But then, people wanted to do even more things on their phones. So, scientists and engineers worked hard to create another new type of phone that could do even more things, like stream videos and music and use GPS navigation. This was 3G.

3G phones work by using special technology to send and receive information really fast. This means you can do things like video chat with someone on the other side of the world, or watch a movie without it stopping or buffering.

So basically, evolution of phones is like a caterpillar turning into a butterfly, except instead of wings and flying, it's more like adding new superpowers to your phone.
