WiFi Calling

It could be that WiFi calling is like HD Voice (VoLTE). Both phones have to have the same capability, and calling a phone on another carrier or a landline won't work. There are just too many un-answered questions at this point in time to know for sure. It's going to take time to sort it all out and for AT&T to work the kinks out.

I have had nothing but good luck with wifi calling.

Good question - I am also wondering.

I unplugged my Microcell.  Most of the time, my IPhone just shows AT&T and 2 bars.  Occassionally it does change to AT&T WiFi.   I never see One bar - so that must be about the time it thinks its better to use WiFi.

However, I got the Microcell in the first place because at my home, even when the icon showed two bars, I would miss or drop calls.   With the Microcell, I always had 4 to 5 bars, and no missed or dropped calls.

So given I am seeing it NOT use WiFi calling in most cases, I am inclined to keep using the Microcell.   I will test further to see.  If I hadn't already bought it, maybe WiFi calling would keep me from doing so.  But given I already own it , there seems little reason not to.

I'd like to see it more inclined to use WiFi calling - like if just 3 bars or less.  Or make it configurable.

I'm in the same situation. Spotty service at my place so wifi calling isn't consistent. My microcell is also pretty inconsistent as in my phone losses connection to it a few times a week. It would be nice if there was a setting to always use wifi calling when connected to a known secure network.

Some have suggested putting in your phone in Airplane Mode when at home. That way it won't connect to the MicroCell's 3G signal and will look for a WiFi network.

Interesting - it actually does work !   I am surprised it allows a phone call at all in Airplane mode.   (I sure hope next time I'm actually ON an airplane, the guy next to me is not talking on phone the whole time !)

However, I know I wouldn't remember to toggle airplane mode on/off everytime I am home.    I think it should favor WiFi to a greater extent than it currently does, or allow it to be configurable.

For now, staying with Microcell seems best choice.

More info about Airplane mode.   Toggling Airplane mode has the Iphone connect via WiFi calling.  But interestingly enough, when I toggle off, it seems to stick with Wifi.  So it does seem to be a decent workaround to coerce it to use WiFi calling.  Of course a better, or at least configurable, default would be better.

I wish AT&T would give preference to wifi calling if the wifi signal is decent.  We have good wifi everywhere but occasionally will get a cell signal of 3 bars (mostly 1 or 2) and wifi calling will not appear.  I would rather always do wifi calling than try to handoff, which may or may not work.

I agree completely.   I went back to using my MicroCell.   If it would favor WiFi more, then I'd not need the Microcell.   I hope this is improved for the future.
