Is there a way to remove custom ringtones from an iPhone without using a Mac or PC? This question has good answers on how to remove ringtones that one may have installed using iTunes on a Mac or PC.

However, it appears to be possible for iPhone users who do not have a Mac or PC to create and install custom ringtones using the iOS Garageband app (see here and here).  Is it possible to remove those user-created custom ringtones from an iPhone (without having to find a Mac or PC with iTunes)?  If so, how?
Follow these steps:


Press Select.
Choose any of your recordings, it doesn’t matter.
Press the button of the box with an arrow pointing up in the bottom left corner.
Press the Ringtone button.
Press Your Ringtones.
Slide left the ringtone(s) you want to delete, and there should be a Delete button.
