Download the ringtone: First, find and download the free ringtone you want to set on your phone. You can use a dedicated ringtone app, a ringtone website, or even create your own using a ringtone maker app.
Locate the ringtone file: Once you have the ringtone file downloaded on your phone, use a file manager app or go to your phone's Downloads folder to locate the file. Note the file's location and name.
Access the sound or ringtone settings: On your phone, go to the Settings menu. Look for the Sound or Sound & Vibration settings. The exact location of this option may vary depending on your phone's make and model.
Set the ringtone: Within the sound or ringtone settings, you'll typically find an option to set your ringtone. It may be labeled as "Ringtone," "Phone Ringtone," or something similar. Tap on that option.
