Got a new phone. Well, it was my stepdaughters then I had problems so Apple swapped it for a new one. When I restored I had a whole lot of accounts of the stepdaughters so if I used Facebook to register for an app I’d get her facebook even though I’d get mine when I used the FB app on the phone. So, on advice, I deleted a whole lot of redundancy accounts and passwords ( who knew they were even there). I suspect it is unrelated but in the interests of full disclosure.
Anyway to the nub of the problem. I am not getting voicemail messages. Callers get a default voice message and I get no messages. Just had a lot of texts saying people have called and not left messages.
Googling, I’m told to click on voicemail and use the setup option top left of screen but there is nothing there.
