I'm curious because I don't see any text under my voicemails when I tap on them, but I've seen videos of that being what you do, and I've read that it doesn't require any activation. I don't see why it would be limited to the iPhone 6s, iPhone 6s Plus, or the iPhone SE (I have an iPhone 6). I've narrowed it down to my carrier (AT&T).
Is there a place where I can see if my carrier supports voicemail transcription?
Thanks in advance!
