To listen to podcasts when there is no WiFi or cellular, you need to first simply download the podcasts.
For example, you can download our Tech You Should Know Podcasts here: https://www.komando.com/podcast/tech-you-should-know/
If you are talking about the show’s podcasts, you can download those too. But, you did not specify what is your favorite podcast player.
On Apple, tap or click the download button next to the episode’s name. Or, if you see the add button, tap or click it, then tap or click the download button. If you don’t see the download button, the episode is already downloaded to your device.
On Google, you can also download podcasts to listen offline, using the Google Play Music Android mobile app.
If you are using another player, let us know so we can lend a hand there if need be.
Hope this helps,
