Once you have the converted ringtone file, it's time to set it as your personalized ringtone on your phone. The process may vary slightly depending on your device and operating system, but generally, you can follow these steps:
Connect your phone to your computer (if using a computer) or locate the converted file on your phone (if using a mobile app).
Transfer the ringtone file to the appropriate folder on your phone designated for ringtones.
On your phone, go to the settings menu and find the sound or ringtone settings.
Locate the option to set a custom ringtone and choose the file you transferred or saved on your phone.
Save the settings, and your personalized pop song ringtone is now set!
