AT&T Wi-Fi calling

Two days after being granted permission to offer Wi-Fi calling by the FCC, AT&T activated this feature today, allowing its customers to make and receive calls and text messages over Wi-Fi when located in areas with poor or no cellular coverage.

How to activate Wi-Fi calling on iPhone

Step 1: Go to Settings > Phone > Wi-Fi Calling.

Step 2: Toggle the switch to activate the feature.

Step 3: You will be asked to confirm the activation of the service and provide an address for emergency services.

Step 4: After completing these steps, you will be notified that Wi-Fi calling will be activated shortly on your device.

What devices support Wi-Fi calling

The company notes that in order to be able to use Wi-Fi calling, you must have an AT& HD Voice compatible device. Of course, iPhone 6 and iPhone 6s are compatible with this carrier feature, but the devices must be running iOS 9 or later. Older iPhones are not compatible. See a list of compatible devices here.

Wi-Fi calling is not your typical VoIP service

Although Wi-Fi calling may sound a lot like VoIP services, it must be noted that it is different in the sense that you are still strictly limited to what you can actually do and where you can call. AT&T Wi-Fi calling is available only to customers in the United States, Puerto Rico, and Virgin Islands. Users who do place calls or send messages internationally using the feature will be charged international rates, just like they would if it they were making a normal phone call or sending a normal text message.

AT&T also notes that a call is not automatically placed over Wi-Fi, unless you have poor or no signal in your current location. If you have decent signal, your call will be placed or received as a normal call.

Wi-Fi calling FAQs

What happens if you leave Wi-Fi coverage? If HD Voice coverage is available in your area (see map) when your Wi-Fi connection is lost, your call will automatically switch to cellular and continue without dropping. If you’re not in an HD Voice coverage, the call will drop.

How do you know if calls are placed over Wi-Fi? You will know you are currently eligible for Wi-Fi calling if your carrier logo changes from “AT&T” to “AT&T Wi-Fi.”

AT&T Wi-Fi calling icon status bar

How to test Wi-Fi calling? To test out Wi-Fi calling, put your iPhone in Airplane Mode, then turn Wi-Fi on. Within a second or two, you should see the AT&T Wi-Fi icon show in your status bar.

    • dnice

      i dont see it as an option

  • Bye bye Verizon

  • Juan Genao

    I activated it and now I have a Wi-Fi next to ATT icon on the top. I’ve always had terrible att service in one particular room of my house so it will be interesting to see how it works.

    My question if for any reason the wifi looses signal during the call what happens, does the call disconnect ?

    • I updated the post to answer your question 🙂

  • Leon Everett

    Was certain I saw this option on back on 8.0 something but not showing up on 8.4? Anyway, any new tweaks?

  • Tdaniels

    1) Which will save more battery, using cell towers or wifi in order to make calls? For example, I’m home and turn on airplane mode, then enable wifi.

    Doesn’t work in my case, I am from NY, I was able to activate it with my iPhone 6 with iOS9 beta but not anymore since I got the 6s.

    I got a new message tho, it asks me to call customer service…

    • They might be slam at this time due to half the US trying to activate the service. If I were you, I’d wait a few hours and try again

      • Jack Wong

        I hope so because this is a very good feature for my apt, I only get 1 block there and it was working great with this wifi calling.

    • f96lrs

      If u have any numbers blocked thure att it won’t work

      • Jack Wong

        I don’t get it?

  • Blip dude

    Actually don’t need it at home, but there are a few dead zones around places I visit that have Wi-Fi where this may be useful. Only issue that I may have with this is, I heard caller ID may not work under Wi-Fi calling and normal calls will show up as “Unknown,” which is an issue because I do get scam calls with “Unknown” ID, so I may only find myself using it only to make calls if that is the case.

  • Wayne Reid

    Just activated it and tested on my 6s plus, worked great, call was very clear .

  • Henry Ramos

    If I travel abroad, and my hotel has wifi, can I use wifi calling to make US calls?

    • M_thoroughbred

      I don’t mean to sound condescending but did you read the article? Or did you just skip right to the comments?

  • Smeltn

    doesnt work on mine.. I have an iPhone 6 Plus running 9.0.2 and when I try and turn it on it says

    We can’t turn on Wi-Fi Calling for your account. This this message is a mistake? Call us at xxx-xxx-xxxx

    • Smeltn

      Fixed.. I actually had to call them and it was still showing my phone as being an iPhone 5s which was my phone last year. Once she changed that to being a 6 plus we were good to go

  • Jose S. Rodriguez

    En Puerto Rico funciona perfecto.
    At&t es la mejor

  • but if it only activates if the coverage is poor; why not just use Facetime Audio?

    • Armed in the Villa

      If you want to call or receive calls from non-Apple phones, you can’t use FaceTime Audio

  • Armed in the Villa

    I’ve activated it and it works fine for both texts and phone calls in my cellular dead-zone apartment. One phone call came through but they couldn’t hear me but all other calls and texts have worked great.

  • Montgomery Tyler

    sweet i was not going to loose my jailbreak just for the wifi calling. Glad there is some light on that.

  • Zachary Sloane

    This is exciting as AT&T has poor service at my office to the point where I have constant issues. Hopefully this helps.

  • Lockywood

    Am I correct in assuming that this new development essentially makes my AT&T MicroCell obsolete?
