Note: While at it, you can also try the option Reset All Settings. It has helped several iPhone users in addressing the issue. Additionally, you can Erase All Content and Settings as well. It will certainly address the issue, but it is a long process that clears all the data on your iPhone.

Clear Deleted Voicemail Messages:

If you are able to successfully delete the voicemail messages only to see them come back after some time then you will have to visit the Deleted Messages in Voicemail tab on the Phone app. It is similar to deleting things from the recycle bin or the deleted photos folder on the iPhone. Deleting the voicemail permanently from the deleted folder will ensure that they won’t reappear in your inbox.

Force Restart your iPhone:

Honestly, this issue of voicemail messages not getting deleted isn’t a major one. You will likely get this sorted with the help of techniques mentioned above. However, if you are unable to do so then you should try force restarting your device. It is like a quick reboot, but it doesn’t affect the data on your iPhone. Here is how you can force restart different models of iPhone.

For iPhone 8 or Later:

Quickly press-release the volume up button, then press-release the volume down button in quick succession. Once done, press-hold the sleep/wake button until the Apple logo appears on the screen.

For iPhone 7 & 7 Plus:

Press-hold the sleep/wake button in tandem with volume down button for at least 7-10 seconds. Do not release them until the Apple logo appears on the screen.

For iPhone 6 Plus & Previous Models:

Press-hold the home and side/top button (as per the model) for 10 seconds. Do not release them until the Apple logo appears on the screen.

Summary:

Again, this issue isn’t as big as it may seem. You will be able to address it on your own. You can also try updating your carrier settings if applicable. You also need to make sure that the voicemail is permanently erased from your iPhone or else it can come back in your inbox.
