Too Long; Didn't Read
If you haven’t heard about what it is, a virtual number is a phone number in the cloud, on the Internet, that can perform functions similar to a computer. Most virtual numbers serve the simple task of forwarding a phone call to a primary phone number. For example, if you give out a virtual number and you have it forwarding to your primary phone number, the person calling your virtual number would never know that they are calling your number, but would be redirected through your virtual number to your phone number.
