How to enable wifi calling on iOS phone

Since updating to 11.4.1 I noticed that WiFi calling is no longer working. Tried all the options I have found. Turned on airplane mode and that doesn’t kick it over to WiFi calling. Also rebooted phone which also did nothing. Wondering if anyone else having the same issue.

HAD No WIFI calling and was still waiting for ATT's ICU team to come up with a fix. Called ATT again and another rep told me after talking with (2) Supervisors that there is no ICO issue with WIFI calling as I was previous told by an ATT rep who also noted the ICU issue in my notes !!??  The current rep told me to turn airplane mode on, turn WIFI on and then turn airplane mode off and it worked - my WIFI calling was restored.  No further comments - it is all inscrutable .  Just moving on.

The solution is how it worked before.  It does not work under IOS 11.4.1

 

Part of the problem appears to be the Wi-Fi service provider.  I notice that at my office which uses Level-3 - it works fine.  At home where I have Comcast / Infinity - it does not.  It may be that Comcast is blocking AT&T Wi-Fi calling.

If you have iPhone X you will not see AT&T wifi on the main screen because of the notch. You see time in the left upper corner and service bars (or lack of bars) followed by the WiFi fan and battery icon in the upper right corner. However, if you check the upper left corner from your lock screen you might see AT&T WiFi or if you swipe down from the upper right corner to access your quick tools you might see AT&T WiFi displayed in the upper left corner. I spent a lot of time on the phone forgetting network settings and rebooting according to instructions from the AT&T rep. I just noticed the display difference a few minutes ago. I hope it is fixed because this is really frustrating. Tech support finally told me to go into an AT&T store and have them run a “smart check”. He said this would let them know if the phone needed to be replaced.  I wish for once a company would acknowledge that there is a known issue, apologize and tell you that as soon as it is resolved we will notify you. How much time did they waste for their customers and poor technicians who are kept in the dark?

I've been having this issues since ios11. What makes it worse, none of my phones now work on the microcell despite help from customer service. I've been with inconsistent WiFi calling for months now.  Att isn't even addressing it. Xfinity is looking pretty good since none of my neighbors on the Verizon radio phones are having any WiFi issues

Same for me.  I've got an iPhone 7 running 11.4.1.  No matter what I do, I can't get wi-fi calling to work.  Although I've been an AT&T customer for over 10 years, I'm afraid to solution may be to get a Verizon phone.  I'm going to go to have a friend with a Verizon phone come to my house tomorrow to test it out.

My sister came over today with her Verizon phone.  We got her on my wi-fi network, turned on airplane mode & wi-fi, and her wi-fi calling worked great.  I couldn't pick-up the call she made to me because my AT&T phone said "no service" and would not allow wi-fi calling.  That proves its an AT&T problem to me. 

 

I just switched to Verizon today and I can now place wi-fi calls.  I'm a happy camper.

Here's my situation and what worked for me. Sharing my experience because this was maddening and I hope I can help as ATT and Apple were not able to help.

 

  • iPhone X with iOS11.4.1
  • ATT cellular service
  • Comcast internet service
  • Motorola MB8600 cable modem
  • Netgear XR500 WiFi router

I get 1 bar of cell service in my house, so rely on WiFi calling. WiFi calling was not working. After trying with ATT and Apple support, I gave Netgear support a call. They solved the problem (for me), which was to disable Netgear Smart Connect on the WiFi router. This is a setting that allows the router to select the best 2.4 GHz or 5 GHz band. Once that setting was disabled and I manually selected my 5 GHz SSID, WiFi calling on my iPhone X came back to life. Even if you don't have a Netgear WiFi router, you might want to check the settings in your brand of router for a similar feature that manages the best band and maintains a single SSID and password for both 2.4 GHz and 5 GHz.

 

Hopefully this helps.

I can confirm that AT&T WIFI Calling works on Cox's internet service.

 

I have a new TP-LINK Archer C2300 wifi router and didn't realize that it blocked WIFI Calling.

 

The issue was that WIFI Calling requires IPSec Passthrough.  Once I enabled that, the AT&T WIFI logo appeared and my calls were crystal clear.

 

There are other potential issues that came up in my research around routers, but they appear to be around NAT Translation and automatic selection of the most optimal wifi band (i.e., 5Ghz or 2.4Ghz).  These were NOT issues for the TP-Link router.

WI FI Calling Issue

Well, I started having WI FI Calling issue a few weeks ago.  I tried everything on this thread and every other thread I could find on the web.  Nothing worked.  Some of the posts here got me thinking.  I have a AT&T gigabit fiber internet connection hooked to a Linksys router.  I have the Linksys router setup in DMZ Plus mode so everything on the network goes through the Linksys to the AT&T router.  If I connect a phone directly to the AT&T router's Wi Fi, I do not have the lost audio issue on Wi Fi calling (but I have had some initial call quality issues).   I then hooked up an AirPort Extreme access point to the AT&T router since AT&T router it is way far away in the basement and wi fi is too weak upstairs.  When I connect to that access point, the Wi Fi calling continues to work.  My son also reported that his VOIP stuff in the video games he plays was not working either. Once I hooked him up directly to the AT&T router, all his stuff started working again.  So, everything that bypasses the Linksys router works fine with Wi Fi calling and VOIP services.  

 

Therefore I suspect there is some conflict somewhere in my Linksys router.  It must be a combination of things since it was working fine for a very long time until a few weeks ago.  Maybe it was from some router software update, I am not sure.  IN any case, I am gonna have to reconfigure my entire network to avoid the issue.  My guess is this issue is all over the place, as my son said he was at Vanderbilt University at a hackathon last weekend and he had the same wi fi calling issues.  He said that had a make shift wi fi network for the event so he wasn't on the university network proper

 

To try and get it to work on Linksys router, I did the following.  I am having OK luck so far but not sure

  • Enabled IPSec
  • Manually set MTU to 1500
  • Triggered port 500  (Not sure this did anything since it makes no sense)
  • Triggered port 4500 (Not sure this did anything since it makes no sense)

 

In any case, mine is working via the direct through AT&T rougher method, but I have a huge network setup attached to my Linksys router and I use things like OPenVPN that are not supported with AT&T so I continue to try to get this to work.

 

FWIW, I am on iOS 12.1

I’m a little unclear. Is your AT&T cable modem actually a router or just a modem? I had a lot of trouble with routers connected to other routers.

The scenarios you describe indicate a problem with the Linksys router, but did WiFi calling work through it before?

If not, you’ll likely need to work through both Linksys and Apple support.

I would look at:

1. Ports closed on the Linksys
2. Make sure IPSec passthrough is allowed
3. Allow all the other pass-thrus as well. If it works, go through each and close the unnecessary ones.
4. If the Linksys is an auto band selector (between 2.4 and 5 MHz), turn that off and configure your IPhone to pick one. I use 2.4 to get good connections throughout the house.
5. Turn off the OpenVPN, just to make sure it isn’t interfering. It shouldn’t but worth checking.
6. Last, upgrade to iOS 12. There were some posts on the AT&T forums that indicated WiFi calling stopped when they upgraded to 11.4. Doubt this is your issue.

I tried to get help through ATT Tech support. They said the escalated my issue after they couldn’t troubleshoot it, including a visit to the ATT store to check my iPhone X hardware which showed no errors. After hearing nothing from them for over 2 weeks, I tried again to fix it myself. I updated my router firmware and it worked. I called ATT and the tech support person said that the person I spoke with never submitted the issue to advanced support. I lost a couple of months worth of reliable service because of this.

Yes. AT&T has really lost it for me over the last 2 years. I have been a wireless customer with them since the very beginning and their pricing is now way out of whack. To make matters worse, coverage in my house has gone from 2-3 bars LTE regularly to 1 bar 4G sporadically (and sometimes only 3G) in the last 18 months. That’s why WiFi Calling was so important to me.

The only way to fight this is to vote with your feet. I will likely leave for T-Mobile and Sprint as they have much better coverage in my area and in Europe.

This should NOT be marked as solved because it is NOT solved!   It's a chronic, ongoing problem and it needs to be fixed.  The only thing I have found that SOMETIMES works is to do a hard reboot of the iPhone.
