A simple way to personalize your phone is to change your phone’s ringtone. You can even pick unique ringtones for the different lines on your phone.
To select an incoming call ringtone for your phone or a line:
1. Select Settings from Home view, and select Basic > Ring Type.
2. If multiple lines are configured on your phone, select the line you want to apply a new ringtone to.
3. From the Ring Type screen, use the Up and Down arrow keys to select the ringtone you want. To hear the ringtone before you change it, press Play. The default ringtone is Low Trill.
