You don't need to turn on Airplane mode though. My phone Says AT&T Wifi with it Airplane mode off.

It says in the description that the phone will intelligently determine if you should use Wifi calling based on cell signal quality. So, to test it, you do need to go to airplane mode and turn on wifi. wait a few seconds and it should display ATTWifi instead of the dots.

If your phone is not in airplane mode and is using ATTwifi calling then likely the phone thinks the cellular quality is too low for HD voice.

Hope that helps!
 
HDVoice and VoLTE are two different things. HDVoice requires VoLTE to work but not the other way around. VoLTE is the ability in this case to send voice over LTE so your data and voice share a connection. HDVoice is a wide-band calling feature that increases the Hz used to transmit the call versus the standard voice compression. Its a codec versus a base technology.
Right, hence the term 'branded'. There is no setting independent of VoLTE to turn HD Voice on/off. VoLTE calls work between carriers that offer it on VoLTE equipped devices, HD Voice works between AT&T customers with HD Voice compatible devices. Thanks though ;-)

This is posted from AT&T's website about wifi calling:
Calling


• Make and receive unlimited domestic calls within the U.S., Puerto Rico, and U.S. Virgin Islands at no additional charge.

• International long distance rates apply for calls made to international numbers.

Texting

• Text messages sent or received using Wi-Fi Calling are counted and charged under your existing rate plan.

and here is the fine print:

Charges: Domestic calls made/received within U.S., Puerto Rico, and U.S.V.I. have no additional charge and won’t count against plan usage limits. For international long distance calls, international rates under your existing rate plan or international package apply. All text messages sent/received are charged under your existing rate plan or international package and will count against usage limits
Don't we ALL have unlimited texting nowadays?

AT&T's wording "charged under your existing plan" made it a bit confusing. But I know my existing plan is "unlimited text" so I'm going to assume that means unlimited Wi-Fi texting as well.
 
Requires a fixed address!? Some of us live/work mobile part-time or full-time, some are in transition, school, some are homeless. Even with a fixed address, why on earth would you want emergency to assume you are at that location? Once again, a system gets dumbed down in assumptions.

911 defaults to cellular if there is any signal. If you only have wifi if you have location services turned on for emergency services on your iPhone it will use the GPS to get your current location. In the event of no GPS signal it uses the address that you enter, which you can easily change at anytime.

Guess if you buy a car and you're expected to provide your own tires and build your own gas stations that's ok with you.

They're not obligated, right?
I don't even know how to respond to this nonsense.

Car manufactures are not obligated to offer you gas or tires. They do provide a set when you buy the car but after that you are on your own. Hybrid cars offer two ways to make the car go, if you only chose to use a single method that will be fine but having a second option to improve your ability will be accepted by many as a great idea.
 
Now I'm curious to see if AT&T will charge roaming if wifi calling is used overseas.

simple fix through a VPN though.

Yes, what ever is unlimited on your plan will be unlimited. They used the wording existing plan because if you pay extra to be able to call other countries at a discounted rate then you will be charged the plan price for doing so.
 
Yes, I realize that they can run at the same time now. I guess I don't really know if it was going through WiFi. I do know that the call quality was always different when I had the WiFi on.
that was probably a placebo effect :)

AT&T is not the only company with HDVoice in thier ad's. Verizon uses the same name because its not a brand but a technology. Also, HDVoice is not everywhere VoLTE is yet.
Edit: Had to look, but T-Mobile uses the term too.
 
So now I get to pay AT&T & Comcast to use my own network and the public internet to route my calls. All to make up for AT&T's crummy service coverage?

Where do I sign up?

I'm not sure why so many people are whining about this.

You've lost NOTHING by having Wi-Fi calling available to you. Before if you were in an area with good Wi-Fi but lousy cellular reception, you couldn't make calls or do SMS at all. Now you can.

So what if it's your own network that you're paying for? You don't pay extra for this.

Before: You can't make calls.
Now: You CAN make calls.

Things have improved at no additional cost to you. Stop complaining. :)

Well this is surprising. Kudos to AT&T for actually delivering. Now where is my Verizon Wi-Fi calling? Oh wait, Verizon has great coverage just about everywhere! Haha, well not exactly. This year my office moved into a building with really thick concrete walls and we're also in the basement. So while I could survive nuclear fallout and tornadoes, my cellular service isn't always super great. I always have a signal, and LTE speeds are often decent, but sometimes the voice quality dips or cuts out depending on where I'm standing and how I'm holding the phone. But I'm probably just holding it wrong. Where is my free bumper? My old free bumper doesn't fit any more.

AT&T has flipped the switch on Wi-Fi calling, making it available to customers with eligible plans that are running iOS 9. MacRumors has received tips from customers who were able to activate Wi-Fi calling and we were able to activate the feature on our own iPhones. A number of readers in our forums are also having success activating Wi-Fi calling.

Wi-Fi calling is a feature that lets calls be placed over a wireless connection when cellular connectivity is poor, functioning much like an AT&T M-Cell does now. It's similar to Apple's own FaceTime Audio feature, which also routes calls over a Wi-Fi connection.

AT&T customers can turn on Wi-Fi calling by going to the Phone section of the Settings app and toggling on the Wi-Fi calling feature. From there, there are a set of steps to walk through, including entering an emergency 911 address. Wi-Fi calling is available on the iPhone 6, 6s, 6 Plus, and 6s Plus running iOS 9.

Customers who want to use Wi-Fi calling need to have AT&T HD voice features enabled, along with an Internet connection. Wi-Fi calling can be used for voice calls within the United States, Puerto Rico, and United States Virgin Islands at no charge. Long distance global voice calls will be charged standard long distance rates.

Once the setup process is complete, customers are receiving notifications letting them know the Wi-Fi calling feature will be available after a short activation period.

AT&T promised to launch Wi-Fi calling alongside iOS 9, but last week announced the feature was delayed due to its inability to get an FCC waiver that would temporarily allow the carrier to forgo offering support options for deaf and hard-of-hearing customers. On Tuesday of this week, AT&T finally received the waiver that it needed to move forward with Wi-Fi calling.

Article Link: Wi-Fi Calling Now Available for AT&T Users

Wi-Fi calling appears to be disabled on AT&T's unlimited data plan. Says contact carrier.

Edit: other users on UDP noted they could enable Wi-Fi calling. So I would have actually called carrier, but simply tried to enable again.. Success! Did not even need Wi-Fi connectivity at time of enabling feature :D

Free bumper, ha, glad thats over with.
 
Just curious what port does the Wi-Fi calling require some work places and businesses nearly block all their ports.

Yeah, we lost nothing, but don't go around saying AT&T did us any favors, either.

Have people forgotten that AT&T is in the business of providing CELLULAR service? Jumping on someone's wireless network is not providing service. It's piggybacking on someone else's infrastructure.

Has anyone considered that this reduces their incentive to improve their network because there is so much wi-fi to be had for FREE on their part? What a deal!

While your plan is older this new feature changes nothing for you. You still have the same limits you had prior. What this changes is your ability to communicate if you're in an area with poor radio coverage but available wifi. If your normal month is 10 text messages then you will still be able to send 10 as before. Billed is just a way of saying this feature uses your current plan in the same way as before.

I still had the "iPhone 4 Free Case Program" app on my iPhone 6 Plus until just before upgrading to the iPhone 6s. Yes, I'm kind of an app hoarder. Yes, I'm clean now. I only have exactly 100 apps installed now, down from about 500-600ish. My iPhone feels so empty. Also, don't look in my closet (iPad).

here I thought I needed to trim back on my 49 apps. I had to look and see how many I had but it feels like I could remove a few right now. 500-600...no 16GB devices for you.
