You need an Activation Code to enable Mobile Security. The activation code is in the following format:
xx-xxxx-xxxxx-xxxxx-xxxxx-xxxxx-xxxxx
The type of Activation Code (also known as a serial number) you purchase for Mobile Security for Enterprise v8.0 determines whether the Data Protection is included in Mobile Security. If the license expires, you will need to register Mobile Security with a new Activation Code. Please consult your local Trend Micro sales representative for more information.
