I pay for the coverage every month but it shows as not covered

Hi pranvera 128,

you would have received an email from Apple containing the receipt for your purchase. In this email you will find a link to complete the setup of your AppleCare coverage and link it to your Apple ID. Once you have done this it should show up on your device. Hope this helps 👍

Where does it show as not covered? What does it show in Settings > General > About
