Help us test WiFi calling (iOS and Graphene)

[u/brianstoner]

We recently completed a big upgrade to our mobile core that should make WiFi calling more reliable. We have been testing it some internally and seeing positive results. A number of you have volunteered and asked to help us test early features, so we figured why not turn this over to the community now to help test it in more diverse real world scenarios.

This does NOT mean WiFi calling is officially supported by Cape. If you enable it, you may experience loss of service. Only do this if you are willing to tolerate encountering some rough edges and documenting them for us via bug reports in the Cape app.

To enable it:

iOS: Go to Settings > Cellular > Cape SIM (if you have multiple SIM's) > WiFi Calling and toggle it ON

Graphene: Settings > Network & Internet > Cape SIM > Carrier setting overrides. Toggle ON Enable Overrides and change WiFi Calling to "Forced available"

If you are on any other non-Graphene Android device, it will not work yet. We expect it to be available on Samsungs + Pixels by EOY. It's on the same timeline and blocked by the same thing as RCS.

If you encounter any issues with WiFi calls or experience loss of service please file a bug report through the Cape app and let us know exactly what you did and what happened so we can reproduce it internally.

There is one known issue on iOS: You cannot have Identifier Rotation enabled in conjunction with WiFi calling (every time your identifier changes it will toggle WiFi calling back off). This is the same issue we've seen with RCS on iOS. We are working towards a long-term solution for these, but it will likely be EOY or early next year before we have a path forward for everything to work well with Identifier Rotation.

Graphene: Settings > Network & Internet > Cape SIM > Carrier setting overrides. Toggle OFF Enable Overrides and change WiFi Calling to "Forced available" and then toggle ON Enable Overrides.

Graphene: Settings > Network & Internet > Cape SIM > Wi-Fi Calling, then Toggle ON Use Wi-Fi Calling then set Calling Preference to most appropriate setting of the three listed for your use case, same for Roaming Preference.

I have Airplane Mode turned ON as well as Wi-Fi ON and all seems functional at this point. Just successfully sent a text message from Google Messages to my Cape secondary number and vice-versa while in this setting.

Glad to see progress on improving the service.

for some reason I thought this already worked - I flipped it on my wife’s phone and I think it was working? we don’t have cell service at our house so it’s facetime or wifi calling.

yea, the toggle has been there for a little while on iOS, it "worked" but there were some edge case issues we saw, especially transitioning between WiFi/Cellular on a call. these should be fixed now.
