Yes, basically this power allow you to go through any solid objects, like go through the ground and appear on the other half of the earth, but I don't think you can go through the ground walk and appear in the next street or city because your are free falling.

Mirio Togata from My Hero Academia anime has this power (Permeation: Mirio's Quirk allowed him to become intangible) He explain this power pretty well (spoiler if you didn't watch My Hero Academia anime yet) https://www.youtube.com/watch?v=m70WSB9qBA4
