You will find the "Sign up" button located at the upper right corner of the FleetMon homepage.
You will presented with the Prices and plans page where you can select your Service Level.
In addition to selecting your Service Level, you will have to fill in the registration form which can be done within a few seconds. Make sure you select an easy username, as you can not change it afterwards. After this step, you will receive a validation e-mail to the e-mail account you have provided to us. Use the special link in that e-mail to activate your FleetMon Account.
Hint: Click on the selection box next to "Remember me" so that you will not have to enter your credentials every time you want to sign in to FleetMon in the future.
