Never used to be that way. They seemed to just spit that feature off as a “Premium” version. I had full V.V.M with text for years. didn’t cost me any extra. (Though now i think of it, it may have been a special thing if u had certain top end devices at the time.)
Anyway, pointless to pay for that when u can just use Google Voice for free. But even the mighty Google, doest do the greatest job of transcribing voicemails. Unless the audio is very clear and loud enough, which it is often not. Not to mention if the person have a accent.
Theses days, i have very few people that call me at all. Only one person (my mother) bothers to leave a VM often. Even then, i usually ignore it and call her later.
So its not really a big deal to have transcription. But it is much nicer to have the VM control in app, and not have to call number and delete message manually to clear pesky notification.
