When you browse or search for podcasts on Apple Podcasts, there's usually no price listed next to them. This is because most podcasts on Apple Podcasts are free to listen to. However, some might have premium content or bonus episodes that require a purchase or subscription.

If a podcast requires a paid subscription, it will be clearly indicated on the podcast's page. You can also check the description of specific episodes, as some might note if they are bonus or premium content.

Remember, even if a podcast is free, you might still need an internet connection to stream episodes, which could result in data charges depending on your plan. Alternatively, you can download episodes when you're connected to Wi-Fi to listen to them offline and avoid using mobile data.
