    It does not require Samsung to do a software update to make Wi-Fi calling work. It just requires AT&T to provision the line for it.

    It does require that the carrier profile that's stored on the device have the proper configuration for WiFi Calling (just like for VoLTE). But yes, mainly the issue is AT&T actually allowing the feature to provision on the line a.k.a. whitelist the IMEI that's being used on the line.

    Source: I've torn apart the MBN files on a Pixel 2 and a Pixel 3, and you can clearly see that the Pixel 2 doesn't have the gateway configured for WiFi Calling for AT&T, but the Pixel 3 modem file shows it (and it of course works).

    They'll finally have to allow more unlocked devices to get VoLTE, but it seems like many of them won't get VoWiFi. The only ones I've heard of getting it are the Pixel 3's, which was probably a condition to be able to sell the Pixel 4.

    Good point. I should have included the 3a and 3aXL as well. The 3a and 3aXL are fully compatible with AT&T, while the 3/3XL don't have B14/29/30.

    That's exactly right. The Wi-Fi calling works very seamlessly as well as a voice over LTE.

    VoLTE and Wi-Fi calling for BYOD Android devices. A very few have VoLTE but no WiFi calling. I switched a line to Spectrum for just that reason.

    When they shut down analog/TDMA they automatically sent free compatible devices to users with no specific requirements to activate them.
