I sold a few things online recently, and every time I had to share my phone number I felt uncomfortable. Even after the sale, some people kept calling me. I wish there was a way to separate my private line from these short-term contacts

I know exactly what you mean. I had the same problem until I decided to Buy anonimous number. It gave me a temporary line I could use just for those situations. Buyers could still reach me, but once everything was done, I didn’t have to worry about unwanted calls anymore. It made the whole process much easier and safer
