I have a iPhone 6S.   WHen I am at home, or anywhere for that matter, I can't get wifi calling to work.  My coverage at home isn't too good so I often miss cell calls.  I was playing around yesterday and

1) Went into settings

2) Selected Cellular

3) Selected Cellular Date Options

4) Went to Enable LTE and turned it off.

 

Now WIFI calling works.  However, at the most I get is 4G on my phone, no more LTE.

 

Problem with the phone or is this the way it is supposed to work?

You won't have LTE since you turned off your Enable LTE option.

Then follow this instructions to turn on your Wi-Fi calling to your device.

  1. Register your E911 address at My T-Mobile.
  2. Turn on Wi-Fi and connect to a Wi-Fi network.
  3. From the Home screen, tap Settings > Phone > Wi-Fi Calling.
  4. If you have an iPhone with an eSIM, tap the line you're making changes to.
  5. Tap the slider next to Wi-Fi Calling on this phone to turn Wi-Fi Calling on.
  6. Tap Update Emergency Address.
  7. Enter your E911 address and tap Save.

Updating the E911 address is a good idea. You should give that a shot and test it out to see if that fixes the issue.

Hey, Dennis!

Any luck with updating your E911 address? If you've updated it and are still having issues, please let us know.

My 911 information was correct, but I went through the process again.  Works sporadically.    Like right now, WiFi calling was not enabled.  I turned off the LTE option, and immediately T-Mobile WiFI appeared on my phone.   I just turned LTE back on, and the WiFi calling display disappeared.

I Have the same Problem with my Iphone 11 Pro Max

Wifi Calling is enabled on my Iphone, when it connects to a Wifi Network, sometimes Wifi Calling works ... 

I just wanted to chime in and confirm that on my iPhone 11 it's sporatic. Sometimes it'll say TMobile Wifi and sometimes it'll try the cellular network. It doesn't seem to matter the signal strength. It could be 1 bar and highly unlikely to actually be able to make a call, and it won't even attempt Wifi. I've tried rebooting, setting the 911 address and switching off LTE. It's very random and very irritating. It's like someone didn't even bother to test the feature in locations with a less than perfect signal or something.

This exact same thing is happening to me on my iPhone 8 (13.3.1).

Thank you for posting.  This is the only workaround I've found to get wi-fi calling to work again.

As described, if I disable LTE my phone immediately starts using T-Mobile Wi-Fi for service and everything works fine.  If i turn LTE back on, my phone immediately drops the Wi-Fi calling network and loses all service (as I'm in a dead zone).

I just switched to T mobile from Verizon and I brought my iPhone 11 Pro Max over. Previously on Verizon I could make WiFi calls but now I can’t since switching. Tech support keeps giving me the run around but it won’t make calls if there is no cell signal. I work in hospitals where coverage isn’t available in certain spots and it’s annoying not being able to send and receive calls. Clearly this seems to be an issue based on the other posts. It doesn’t change anything for me if I turn off LTE. Does anyone else have the same issue or have found a solution? T mobile is checking with their engineers but based on this working previously with Verizon I think it’s a T mobile thing.

Wow, huge article but very useful. Thanks.

Pixel  2 here. Same issue as described June 2020. Wifi i calling is intermittent. Nobody has a straight answer or cure for the problem. Just came from Verizon and Verizon wifi calling worked flawlessly. TMobile works great everywhere I go... Except my home
