ATT, once known as Cingular, is one of the major cellular service providers in the United States as well as throughout the rest of the world. With most AT&T cell phones, it’s pretty easy to get free ringtones installed without too much work. First, you must download the free ringtone, music, or sound file from either the internet or your computer. After that, all you have to do is go into “My Music” or the respective sound setting configuration area and set your newly installed file as your default ringtone.
In addition to this, there are also several sites that offer free text message alert tones for ATT users as well – something interesting worth checking out if you are one who is into texting a lot.
