Your Advance A5 Plus LTE sports a microSD memory card reader. If your laptop or personal computer can also read that card format (Most laptops are so-equipped), you should be able to transfer a music file
If all of the above tips do not work with your BLU Advance A5 Plus LTE or if you don't want to buy extra accessories, you can still use one of various free '3G Uploader' services available online. You should find plenty with a simple Katapulco.com search. 3G uploaders are simple to use: Save your own music on their web site and they will return a temporary URL. Pointing your BLU Advance A5 Plus LTE's web browser to that address should download the free ringtone.
