As of 2015, Sprint does not allow users to download ringtones from its website. Sprint users who sign up for the optional Sprint Music Plus service are able to download ringtones directly to their phone using the official Sprint Music Plus app.
The Sprint Music Plus app allows users the option of setting a custom ringtone for any contact in a user's address book. Aside from ringtones, users can stream and download songs and full albums. The app is available for both Android and Apple smartphones and is downloadable for free from iTunes or Google Play. Currently, the Android version of the app is rated three and a half stars on Google Play, and the iPhone version is rated slightly lower on iTunes.
