I changed my voicemail several years ago to say "Hi, you've reached NAME. There is no voicemail on this service, so please send me an SMS or Whatsapp message, or email me EMAIL. And have a great day!"
I still get a voicemail notification every few weeks, though I have no idea from who because I have absolved myself of ever listening to them again.
Unlike having no voicemail, I can still provide a personalised message to the person calling me (and as a business owner, I do want people calling me).
