I had voicemail deactivated for decades. I’m not reachable? Call again later or write a message. Now that I’m older I had to reactivate it because contractors, pharmacy etc. expect and use it to send me information.

I hate voice messages in WhatsApp and the like but I can see the usage for others. My wife communicates with her friends this way. When you have to watch the kids you can send and listen to messages without having to look at your phone.
