Wifi ATT calling now available!

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.

Wow. Works really well.

Clear and loud. First time it was only a one way, but now it works.

It may mean that your cell coverage is too good.

Try turning off cell service. Airplane mode and then turn on wifi

It makes a decision based on the cell quality. As you can see I have -114 or worse

Don't worry. Somewhere in your house, you may have poor service.

Have you tried a call? I called my local CVS. What a difference!

I guess one needs iPhone 6 or newer that has HD voice. iOS 9 or better.

Is this only Apple phones or all?

Good bye flaky microcell

Yes, it is official. Only iOS users, no Android.

'In order to use Wi-Fi Calling, customers just need a compatible device with iOS 9 installed, a postpaid wireless account set-up for HD Voice and a Wi-Fi Internet connection. This includes a Wi-Fi connection set up at home or the office. - See more at: http://about.att.com/innovationblog/10082015wificalling#sthash.R9tZke8a.dpuf'

My understanding is that it will not work from an overseas hotel.

It's AT&T wifi calling, not whatever local carrier your cell phone is using.

You would use Skype, or another wifi calling, or FaceTime audio to another iOS device.

I honestly don't know the reason for only iOS 9 and iPhones have AT&T wifi calling and not Android.

Anybody?

I assume it will roll out soon, but I don't know. ???

A+ for the effort, KJ. But those are global stats.

AT&T is a US market, where it is more evenly split.

Back on topic. It is hard to understand. Maybe because iOS device are most likely to be at the same iOS version level, compared to android? Or iOS consumers are more profitable to ATT?

Both OS ' have had wifi calling for many years. Skype, for example. And Apple also has had FaceTime for years. Also from other apps, both iOS and Android. .

I've had an ATT microcell for more than 6 years, which is basically wifi calling.

So both platforms have been capable, and T-Mobile has had iOS wifi call for years too.

So I'm a bit puzzled. But I think Android is not far behind regrading wifi calling.

Att seems to require HD Voice. That was not necessary with the microcell. Only a 3G device, not VoLTE.

I don't think it is an Android vs IOS issue. Clearly all platforms have had wifi calling via Skype, third party apps, and also FaceTime Audio in iOS. With some limitations: phone to phone, etc. and T-Mobile has had it for a while hooked into their carrier.

Seems to me a software issue mostly. Maybe I saw the same article as KevinJames. Currently no Android phones ready for ATT and also waiting for Android 6.0 later this year.

AT&T is doing something different than what I had with their microcell or any wifi app before.

1) it is VoLTE. voice over the LTE data network. The microcell used 3G cellular connections and the box hooked into your home wifi. This new wifi feature works without a box and into almost any accessible wifi ( assuming some correct data channels are enabled. Pretty much any 3G cell phone worked under the microcell.

So when on the microcell, my carrier signal would rise from -120 to -65 dbm

When using FaceTime or Skype or another third party app, the cellular signal was irrelevant.

2) in this new AT&T wifi, the phone software has to 1)monitor and 2) manage the cellular signal. I noticed that if I have 2 dots or more, it will use the cell tower. Less than 2, and it is on AT&T wifi.

All without a special app, but part of the native OS

When I'm on the AT&T wifi, the carrier is back at -120 or so.

So that is more complicated than what we had before. On iOS it's only available on iPhone 6 & S series with iOS 9.

So I'm guessing that is the delay with. Android and others. Software update to use it and hardware to do the handoff between cell and wifi smoothly.

'There are currently no Android phones available that can take advantage of AT&T’s WiFi calling feature, but we suspect AT&T will be working closely with Samsung, LG and HTC to ensure that the feature is enabled with the Android 6.0 software updates that should start landing before the year is out.'
