Hello! I understand you're having trouble playing DI.FM with your mobile data connection on your Android device. Let's see if we can get you streaming smoothly.

First, just to clarify: Are you able to play DI.FM fine when connected to Wi-Fi, but it won't play when you switch to mobile data? Also, is this happening in the DI.FM app specifically, or if you try to play from a browser?

Assuming it's the DI.FM app and mobile data, here are a few steps we can try together:

1. Check Mobile Data Permission for the App
Since you're on Android 10 and WebKit-based environment, the app might not have permission to use mobile data. Go to your phone's Settings > Apps > DI.FM (or the name of the app you're using), then find Data Usage or Mobile Data, and make sure mobile data access is enabled. Sometimes, apps are restricted from using cellular data to save data3.

2. Verify Network Connection
Make sure your mobile data works with other apps or websites. Sometimes the network might be restricted or unstable.

3. Check DI.FM App Settings
Open DI.FM app, go to settings or player settings, and look for any option that limits streaming to Wi-Fi only. If found, disable that so it can stream over cellular.

4. Restart the App and Device
Close the DI.FM app completely, then restart your phone and try again.

5. Update the DI.FM App
Ensure you have the latest version of the app installed, as updates often fix streaming or connectivity bugs.

If after these steps it still won't play on mobile data, please let me know which step you've tried and we can dig deeper or explore alternative solutions. Would you like me to guide you through any of the steps more explicitly?
