Hi,
We're sorry to hear about the frustration and the time you've already spent on this.
If Mobile Security is still showing the Free Version after reinstalling, it usually means the app is not yet linked to the Trend Micro account where the active subscription is registered. Instead of entering the code again, please try signing in to the app using the same Trend Micro account associated with your subscription. Here's the link for your reference:
Activate Trend Micro Mobile Security on Android Devices: Step-by-Step Guide
If you're still being prompted to upgrade after signing in, please let us know:
- - Is this an Android or iOS device?
- - Are you signing in with your Trend Micro account or using an activation code?
- - What exact message do you see in the app?
We'll be happy to help you get your remaining 12-month subscription recognized.
