A guy from an online coding course I joined mentioned using a virtual phone number toll-free for his side project, and I asked about it since I was curious. Turns out, he was using it mostly for family to reach him without anyone getting charged. I thought that was kind of brilliant. I set one up too—my parents use it now when they need to call, and they like that it doesn't cost anything. It’s one less thing to explain to them every week.
