Voicemail messages but no voicemail

[KernelPanic]

Ever since the iOS14 update I keep getting messages saying you have a new voicemail. When I go into voicemail it says you have no new messages or saved messages.

You need to call your mobile from another phone and leave yourself a message.

Then listen to it and delete it on your mobile which will reset the stuckk notification.

Ok thanks. That seems to have worked. So far no more messages

Great advice, your solution cleared the persistent New Voicemail message on my hand-me-down Samsung Galaxy J3 but to get it to clear as your instructions, I first had to reset the phone to accept Voicemail, I then rang from another phone and left a voicemail message.  After listening to the message on the problem phone, I then turned off the phone and turned on the phone and bingo - no persistent voicemail message.  Thanks.

Hello MI5 tried your solution however I'm not offered to the opportunity to leave a message!!

It states that I'm unable to leave a message.

Should add that I've just switched to O? Is there a voicemail on voicemail off function I'm missing on my iPhone maybe?
