H.870
So, there's a group of grown-up people who make laws and rules for other grown-up people to follow. One of the things they do is decide how phones talk to each other when you use them to call people in other countries.
Now, there's a new rule they made called h.870, which is basically a set of instructions that makes it easier for phones in different countries to talk to each other without any problems.
Imagine you have a friend who speaks a different language than you - it might be hard to understand each other, right? But if you both had a special dictionary that lets you translate words quickly, then it would be easier to talk and understand each other.
That's kind of what h.870 does - it creates a special dictionary for phones so they can understand each other better when people call from different countries. This makes it easier for people all over the world to stay connected and talk to each other, even if they don't speak the same language.
