Unfortunately you can't use anything from the SD card as a ringtone, the phone won't recognize it. What you can do however, is make your own ringtones. Using any mp3 file you have on a computer you can upload it as an attatchment with your favorite email client and send it to your phone as a ringtone. In the email send it to yournumber@vzwpix.com, be sure to include a subject and it will arrive on your phone as a MMS. Play the message on your phone and you can click "options" and "save as ringtone".

 

Use ringtone editors to get the bits of song you want. Google: Myxer, Audacity, Funformobile.com ..just to name a few.

Just as an addition to nmchileman's good response, If you already have a sound effect or music clip on your phone, you can just text yourself with the sound and you will also get the option to save as ringtone.

use online ringtone maker, choose delivery by email and enter the email as yournumber@vzwpix.com

 If I send a ringtone to mynumber@vzwpix.com, will I get charged for data or does it count as a picture message?

It will count as a picture message, there will be no additional data charge.

Thanks nmchileman!   I tried it and now I just need to make them louder.  I can barely hear them!
