If you're on iOS, look for the podcast app with the purple icon. You might need to download that one too - it doesn't come as standard on your phone anymore. If you're on Android, you might have Google podcasts or maybe you've got another podcast app. I recommend pocket casts, pocket casts in the app store. So download your podcast app, then search in the app for Luke's English podcast, and then subscribe to it. And your life will just get better from there. Simply subscribing won't really help your English at all.
