In early 2007, Netzero began advertising Netzero Voice and PrivatePhone at Best Buy by making special PrivatePhone CDs which included the videos featured on the web site and a phone number (1-866-755-7055) where people could sign up by telephone if they called with a mobile phone (so that people could receive their account information by text message).
The professor explains that you can use PrivatePhone to give your number out when you shop and all future calls from retailers go straight to voicemail that one can check quickly over the phone.
[6] PrivatePhone originally announced that on December 31, 2007, they would be ending their service, but in January they extended the closure date to February 19, 2008.
At that time, new signups were no longer accepted, and PrivatePhone sent a message to all of its users on January 16, 2008 informing them about its discontinuation.
Despite the service ending on February 19, 2008, NetZero still gave existing users the opportunity to keep their number.
