Quick answer

Open Settings, choose Sounds and vibration, tap Ringtone, select the SIM if your phone asks, and use the plus button to add a compatible audio file. The exact labels can vary by Galaxy model and One UI version, but the route is usually very similar. Samsung also lets you assign a separate ringtone to an individual contact.

Use audio that you created, licensed or downloaded from a source that permits your intended use. Preview the file before selecting it and avoid files with a long silent opening.

Add an MP3 as the main Samsung ringtone

  1. Save the audio file locally on your Galaxy phone.
  2. Open Settings.
  3. Tap Sounds and vibration.
  4. Tap Ringtone.
  5. Select SIM 1 or SIM 2 if the device shows both.
  6. Tap the plus icon near the top of the screen.
  7. Find the file in Downloads, Audio or another local folder.
  8. Select the file and tap Done.

Return to the Ringtone screen and tap the selected sound to preview it. Make a test call from another phone so you can check the real speaker volume and starting point.

Turn off selected highlights when necessary

Some Samsung sound pickers show a Play selected highlights only option. When enabled, the phone may choose a section from the middle of a song. Turn it off if you prepared a short ringtone and want playback to begin at the start.

Use a different ringtone for each SIM

Dual-SIM Galaxy phones can keep separate call sounds. Open the Ringtone menu, choose the first SIM and select its tone. Return to the previous screen, choose the second SIM and repeat the process. This is useful when one number is personal and the other is for work.

Set a Samsung ringtone for one contact

Open Contacts, select the person and tap Edit. Look for View more, Ringtone, or Change ringtone. Choose the desired sound and save the contact. Menu placement can differ by model, software version and the account used to store the contact.

A contact-specific ringtone normally overrides the default sound only when that saved number calls. Test it after saving, especially if the same person has several numbers.

If the audio file does not appear

Renaming an unsupported file to end in .mp3 does not convert it. Use a trusted audio converter and keep a backup of the original.

If the ringtone is silent or too quiet

Open Settings > Sounds and vibration > Volume and raise the Ringtone slider. Confirm Sound mode is selected instead of Vibrate or Mute. Review Do not disturb settings and disconnect Bluetooth audio temporarily during testing.

If only one caller is silent, open that contact and check whether a separate sound was assigned. Also verify that the number is not blocked.

Frequently asked questions

Can a Samsung Galaxy use an MP3 ringtone?

Yes. Current Galaxy phones can generally select a locally stored MP3 from the ringtone picker.

Can I use a separate ringtone for each contact?

Yes. Open the contact, choose Edit and look for its ringtone setting. The option may appear under View more.

Why does my Samsung play the middle of the audio?

The selected-highlights feature may be active. Disable it when you want playback to start at the beginning.

Final check

Make one test call with Bluetooth disconnected. Confirm the correct SIM, volume and start point. A clear 15-to-30-second clip usually works better than a full song because the recognisable part begins immediately.
