Communication company USMobile, Inc. has launched its free version of Scrambl3, a mobile App for iOS and Android enabling private calls and messages, the company said.
New Scrambl3 users are only asked to provide a username and password. Other free voice and messaging apps require that you verify your cellphone number, request access to your private cellphone contacts, and may also ask for your email address.
Scrambl3 users privately exchange their usernames and add them to their respective Scrambl3 Black Book contact listing. No unwanted calls or messages are possible on the private network.
USMobile is an Irvine, California-based company.
