Changing the DTMF Tone of your Android Device

Follow

Last updated by Rod McRae

After bringing a phone from another carrier, some customers find that they have issues using voicemail. They will enter the security PIN, but the system doesn't acknowledge that a PIN was entered and repeatedly asks for it over and over again.

When this happens you will need to adjust the Dual Tone Multi Frequency (DTMF) tones. 

 To do that, follow these steps

  1. Tap the phone icon
  2. Tap the three dots (or the More button) in the upper right of the screen to open the Menu
  3. Tap Settings
  4. Tap Call
  5. Tap DTMF tones
  6. Select the option for Long

 

For some versions of Android, you may have to do the following.

  1. Tap the phone icon
  2. Tap the Menu button (located in the upper right corner)
  3. Tap Settings
  4. Tap Calls
  5. Tap Sounds and vibration
  6. Tap Dialpad Tones to enable
  7. Tap Dialpad tone length and select the option for Long
