Steps:
- Before attempting this make sure that your cell phone is able to receive ringtones in this way.
- Simply attach the ringtone file that you downloaded to an e-mail and send it to your cell phone or if you create your own mp3 file to use as a ringtone make sure the file size is under 200k otherwise it can't be used as a ringtone but will be saved as a sound file. If you do not know your cellphone's e-mail address you will be able to find it from the list below.
- Once your cell phone has received your ringtone review your manual to see how to apply it as a ringtone with your specific make and model phone.
