ELI5: Explain Like I'm 5

International Telecommunication Union

The International Telecommunication Union (ITU) is like a big club for people from different countries who work together to make sure that everyone can talk to each other using things like phones and computers. They make sure that when you call someone in a different country, your phone can understand their phone and everyone can hear each other clearly.

The ITU also makes rules for things like how much money you have to pay to use the internet in different countries and how to make sure that everyone's phone calls and texts stay private. They want to make sure that everyone in the world has access to these things, and they help countries who don't have as much technology as others to catch up.

The people who work for ITU are like referees for phones and computers, making sure everyone plays fair and gets along. They meet together and talk about ways to improve the technology and make it better for everyone. That way, you can call your friends who live far away or play games with someone on the other side of the world without any problems.
