What’s the most hassle-free way to call someone in Belgium regularly from abroad? ?

Hey everyone! A quick welcome to those new here. So, I was on the hunt for a better way to stay in touch with a friend who's temporarily based in Belgium. While watching a random YouTube video, an ad popped up about using a virtual phone number Belgium, and I clicked out of curiosity. Ended up setting it up in minutes, and honestly, it’s been useful. The audio quality is stable, and it doesn’t tie me to one device, which is a big plus.
