In the 10-12 years since I last had a Blackberry, no phone that I've had has come close to it in terms of an email device.

Current phones do a lot of things much better (apps, games app stores etc), but not email, and voice calls have only recently started to show some advantages (Voice over LTE/Voice over WiFi/HD Calls etc).

BlackBerry had wifi calling since 2007.

Not the only one, either. I actually had the Nokia 6086 (https://www.gsmarena.com/nokia_6086-1798.php) which had UMA. I got it through T-Mobile and got my first wifi router ever, the WRT-54GTM ("TM" for T-Mobile), through their HotSpot@Home service. There was a small monthly fee in exchange for unlimited wifi calling.

I think the iPhone got a lot of customers who were on the fence about blackberries. I wanted better email, but the stereotype of the PHB blackberry owner was just fading into obsolescence when the iPhone 3G showed up and killed half of everything.

AFAICT from the Internets, BB10 OS actually supports VoLTE, but there's no way to manually enable it. Given the support status of the devices no carrier will provision VoLTE on it for you these days either, so we're out of luck.

That brings me back. I worked on it way back when. The IMS stack works over WiFi too; it could probably work with any generic SIP provider and hook into the native phone app.

I wonder if it's something in the baseband, if you can get QXDM to talk to the modem, you could probably enable it.

You just need to enable a diag modem on bb10, if you can, then voila.

Something like this.

I’m fairly sure that Blackberry devices were the first to do Wi-Fi calling in the US on T-Mobile.
