How can I change the ringtone on my phone - Samsung SGH-E900 Cellular Phone

What kind of phone? Most newer phones have apps you can download for free to make your own ringtone but especially for iphones it is not easy. If you are somewhat tech savvy search your phone model in google and "custom ringtones"

If not so tech savvy its easiest to shell out the money for a already made ringtone of the music you want. Only purchase ringtones from official stores on your phone
Ex; Iphone: Itunes
Android: android market or google play.
I suggest not using your computer to buy ringtones or searching for ringtones on your computer browser in general. Theres lots of scams out there.

To change the ringtone press MENU, and then tap Settings. Tap Personalize > Default ringtone. The Phone ringtone selection menu then opens and you can scroll through the available ringtones and tap the ringtone you want to use then tap OK.

Change your ringtone
1. In Menu mode, select Settings → Phone profiles.
2. Scroll to the phone profile you are using.
3. Press <Options> → Edit.
4. Select Voice call ringtone.
5. Select a ringtone category → a ringtone.
6. Press <Save>.

you can easily change the ringtone. Follow these steps:

1. In Idle mode, press <Menu>--> Settings --> Phone Settings --> Phone Profiles.

2. Scroll to a profile.

3 Press <Options>--> Edit -->Voice call ringtone.

4. Select a ringtone category --> a ringtone.

5. Press <Options> --> Save profile.

go to your general profile settings
