Balony. I no longer have AT&T but working fine on Verizon.AT&T tells me wifi calling isn't available for iPhone X yet and that this is an Apple issue to be addressed through a future software release.
I am skeptical. Is wifi calling working for you on the X? (and you have AT&T)
Wish AT&T would prioritize Wi-Fi calling over cellular. I have signal issues in my house too but cellular often overrides Wi-Fi for some reason and the call quality is horrendous. It got so bad that AT&T sent me a microcell, but the problem with that is that Wi-Fi calling and the microcell kind of conflict with each other. I had to disable Wi-Fi calling and that works fine at home, but I have to remember to enable it every time I leave the house and I never do.
Others have mentioned the scenario of being in an area with weak cellular signal (such as a basement, or deep inside an office building). For me the biggest benefit of Wifi calling is for international travel. I’m in Australia right now on a business trip, and can make and receive calls to and from the USA as if I was at home.... with no “roaming” fees. Since 90% of the time I’m on the hotel wifi or office wifi, it works great.
If you just turn off your cellular with WiFi running, it'll just switch over. If you go out and need cellular it obviously has to be re-enabled, but it's super quick from the new CC (and you'll be quickly reminded if you don't have a data connection).
A while back I was having the same issue, weak cell, and it would bounce between cell and wifi, so I just disable / force WiFi calling in the house most of the time.
I’ve done that but I always forget to turn airplane mode off when I leave my house. Wish there was a way to automate that process using IFTTT or something similar. It’s just annoying to have to turn off cellular every time I get home and then remember to turn it back on when I leave. I know you said that I’ll be reminded that I don’t have a data connection but I’ll have to experiment with that.
If you have a weak cellular signal but full Wi-Fi you can still make phone calls and text.
Actually with 0 cellular signal but full Wi-Fi you can make calls and text.
It’s pretty awesome.
