SEC+

If this is about Southeastern Conference: – About SEC Network/SEC Network+ - Southeastern Conference Sports

SEC+ is complimentary to your SEC Network channel from your TV provider. SEC+ is accessible through the ESPN app.

Who is your TV provider, and is SEC Network part of your package with them?

If you recently changed TV providers, then see if the new one carries this network: SEC Network Channel Finder. If you no longer have a pay TV provider, then you also lost access to SEC+.

If you are not signed in for SEC+, then sign in with your TV provider credentials.

What is SEC+ to you?

Is it a an App you had downloaded?

Was it a channel inside the Apple TV App?

What TV do you have?

Is it a smart TV?

Do you have an Apple TV box connected to it?

If you want any kind of help, you will need to explain in as much detail as possible what SEC+ was, how you were accessing it, and what your setup is. TV make and model, Apple TV model and tvOS version it is running. Etc....
