Discover country?

then how to discover it?

Did you mean opening a new terminal in another country using coins?

Buying another county and opening two terminals and driving the route still did not complete this objective as of 1-30-2021. So that's either not how to do it, or it's bugged and needs patching.

I've tried too and can’t get it.

How do you discover a country!? Would love to know how to do it? Can anyone help !?

You just have to unlock a new country

Discover country

No, he’s right, I started in Cali, got to this mission, “discover country” it took some gold but bought Mexico then bought the cheapest terminal within Mexico and completed said objective.
