I just got it too. I wonder what it does, couldn't find any info on the internet...

My first guess was something related to the iPhone X, but that doesn't make much sense.

Carrier update 29.1 was support for Project Loon; adding emergency 900Mhz (LTE band 8). So maybe similar?

Actually I think 29.1 was an update that tunnels Personal Hotspot data through a new APN, this allows AT&T to keep track of how much tethering data you are using vs. regular phone data. version 30.0 was Prroject Loon.
 
Anything to do with voice mail transcription being broken after updating to 11.0? My wife hates 11.0, for that simple reason. It was supposedly an AT&T problem.

I have not seen any notice of what 30.1 is, but re: your wife's problem, my daughter had the same - she fixed it by calling her phone number. It took her to her to voicemail, she entered her VM password, she listened to the messages, hung up, (she my have then reset her phone), and the transcription and VVM was back - although it did remove any voice mails older than like 30 days or so. It sounds like the AT&T system had to reconnect with the phone or something. YMMV.
 
Yeah, we found a thread on AT&T forums and went step by step to get it to work again. Problem now is, it's intermittent.
 
Settings -> General -> About look for the Carrier line towards the bottom of the screen.
Excellent. I learned something. BTW I’m in Dallas and updated to latest iOS on ATT iPhone 6s plus and no carrier update yet. Maybe it is just for newer phones.
 
When I got the update I was hoping for wifi-calling and HD voice. I'm on ATT prepaid and we don't get those features. Don't know why.
 
Seems like a few carriers got a similar update. They happen here and there (with and without iOS updates) and often we don't really know what's part of them.

Correct.
Carrier updates are to improve the way the device communicates and connects to the carriers network. They don't do anything different or add any iOS features that you will notice.

Sometimes they can add or basically expose something that wasn't before, like WiFi calling can appear if a carrier starts supporting it or something like that. But, yeah, in an overall sense, they don't have new features that they add or anything like that.

Yes, that would be a nice and noticeable addition. 🙂
But 90% of the time is settings and changes behind the scenes that the average consumer won't notice.
