Our goal was at first to be able to produce a reception maximized phone and then, later, add new security features for the second Certum 2 model. However, based on the good feedback, petitions and recent security issue headlines (such as Facebook’s) we decided to change our plans!

We will direct our resources to putting the final touches to the Certum 2 phone because we believe that superior reception accompanied by the new security features will raise greater interest among wide audiences. Further information will be provided later.
