Yes, you can listen to Apple Podcasts without WiFi. You just need to download the episodes you want to listen to while you're connected to WiFi or using mobile data. Here's how you can do it:

1. Open the Apple Podcasts app on your device.
2. Find the podcast episode you want to listen to offline.
3. Tap on the '+' icon to add the episode to your library.
4. After it's added to your library, a download icon (cloud with a downward arrow) will appear. Tap on it to download the episode.
5. Once the episode is downloaded, you can listen to it anytime without needing an internet connection.

Remember, downloading episodes can take up space on your device, so be sure to manage your storage appropriately.
