Even if you don’t really care about online security, spam protection, or scammers, which is honestly kind of weird because it’s something you should think about nowadays, I’m sure a lot of people still prefer to separate personal life from work. I have a lot of communication with clients that I only talk to once. I definitely don’t want to give them my personal phone number, and virtual numbers from smsfast.com are really convenient for that. My real phone number is only for personal life, personal chats, friends, and family.
