GOT HERE
The BLU J010 is equipped with a microSD memory card reader. If your laptop or personal computer can also read that kind of card (Most notebooks are so-equipped), you should be able to transfer music files
The Joy is equipped with Bluetooth version 4.0, which lets you connect to your computer wirelessly. Just pair phone and computer together and drag and drop any music file from your computer to your BLU Joy.
If the above-mentioned tips fail or if you don't want to buy extra accessories, you can always use one of various free '3G Uploader' services available online. You should find plenty with a simple Katapulco.com search. 3G uploaders are easy to use: Transfer your own ringtones on their web site and they will return a URL. Pointing your BLU Joy's web browser to that address will download the free ringtone.
