Can I Set a Music File (MP3) as the Ringtone on my SGH-T199?
Your device can turn MP3 files you have downloaded into custom ringtones. You can also set up custom ringtones for your contacts.
To select a downloaded or transferred MP3 ringtone, from the standby screen, press Menu > Media > Music. Select a song, and press Options > Set as > Ringtones.
To use an MP3 ringtone for a single contact, select a song and press Options > Set as > Individual ringtone. Select Search contact, highlight a contact from your contacts list, and press .
