How-to How to Delete All Voicemail Messages in iOS 7 on iPhone?
Voicemails on your iPhone actually reside on the server (of your carrier) and are pushed to your device. You can delete them by swiping on the voicemail and tapping on delete. But this only puts them inside a “Deleted Voicemail” list.
While “Clear All” used to work without a trouble till iOS 6, with the recent iOS 7 upgrade, some users are pointing to issues like a grayed out “Clear All” which doesn’t let you delete all voicemail messages at once. That’s kind of buggy and a pain (just like a grayed out Wifi). Here’s how to fix:
The most common problem we hear about is the grayed out “Clear All”.
How to Delete All Voicemail Messages in iOS 7
#1. One of the first reasons that we encountered is a large number of deleted voicemails. If your list is huge, scroll down till the bottom of the list and wait for a few seconds (or a minute). In some cases, scrolling down and waiting for a minute or two enables the “Clear All” and you can tap that to delete the messages.
#2. If that doesn’t work, try this: within the Deleted Voicemail list, when “Clear All” is grayed out, tap on a single Voicemail. The voicemail plays. Tap on it again to stop playing the voicemail. Does the “Clear All” button get enabled now? If yes, tap it and delete all voicemails from your iPhone.
#3. In some cases, where the list is huge, “Clear All” stays grayed out or only clears a few messages at once. This is an issue with memory and processing because the list of deleted voicemails is huge (running into thousands). In these cases, it would be best to reset/restore your iPhone with selective data backup (photos, apps and contacts).
#4. You can also try this: Go to Settings → General → Reset Network Settings. Wait for the iPhone to reset/respring and then try steps #1 or #2 to clear/delete all voicemail from your iPhone.
