Issues related to voicemails are quite common across iPhone. Most users delete voicemails after listening, but sometimes due to some unknown reasons the voicemail on the iPhone won't delete no matter what you do. And if it gets deleted, it comes back after some time. Fortunately, there are some solutions available. Following are some effective solutions:

Method 1: Set Your Phone to Airplane Mode

This is one of the easiest solutions for "iPhone won't delete voicemail" issue. Many users have succeeded in deleting voicemails via this method. The method is quite simple as all you have to do is set your phone to Airplane mode. Follow these instructions:

  3. Turn off the "Airplane mode". Your deleted voicemail messages won't come back.


Method 2: Delete from Network

Sometimes deleting voicemail messages from your iPhone solves the problem. However, if the Airplane mode method doesn't solve the problem, then you will need to delete those messages directly from server or network. Follow these instructions:

  1. Open the Phone app on your iPhone.
  2. From the bottom of the screen, tap the "keyboard" icon. The dialer will appear.
  3. Now use the dialer to dial your own telephone number. It will allow you to access your voicemail. Or dial "*86" if you are using Verizon Wireless or hold the "1" key if you are using "AT & T".
