virtual number

What’s a reliable way to call someone in Chile without relying on third-party apps or bad connections?

I overheard a couple talking about international numbers on the train (weirdly specific, I know), and one of them dropped something about virtual phone number Chile. I made a note on my phone out of pure curiosity. When I looked it up later, I saw Kata Telecom offered exactly that. I’ve got a buddy teaching in Santiago, so I signed up just to try it. It’s working fine, no delays, and it saves us both from using flaky third-party apps all the time.
