Kyocera Slider Remix KX5 / Slider Sonic

you can purchase the micro-sd card and make your own ringtone with ringtone software like RingTone Ripper. Once you put the ringtone on the sd card, you can assign the mp3 as a ringtone. You can also move full length mp3's by dragging and dropping them into the card and putting the card in the phone, or buy a cable and you can do it that way too. Go to this link and you will be able to learn about it and get an owners manual too.

I loaded wma files from an external card reader. When I put the flash card into the phone, and push "OK" on the music player, I get the message, "No file present in card and phone". What's going on?
