Hi, adele.g.56.

Let's try reactivating your subscription on the Trend Micro Mobile Security app. Make sure to follow the steps below:

1. Open your Trend Micro app. 
2. Scroll down then tap Settings. 
3. On the Settings, "Sign out" to sign out your Trend Micro account.
4. After that, go to Settings again then tap "Set up account" to sign in to your Trend Micro account.

Let us know if you need further assistance.

I have tried this a couple of times and still shows expired. What next?

Thank you for your response, adele.g.56.

Upon checking here, you already have 4 devices registered on your subscription. You'll need to delete one to protect your phone. Sign in to your Trend Micro MyAccount to check and delete.
