* Depending on your phone brand, you may need a specific format of audio file to use as a ringtone. We've provided three common formats that will work for most phones. If in doubt, try the MP3 version first, it will work with most devices like Android powered phones, Blackberry, and many others. If that fails, try the M4A version. iPhone users should use the M4R file. Additionally, you may need to download the ringtones on this site to your desktop computer first, and transfer them to your phone.
