That's the odd thing, is that the voice calls are functional in the normal way. I don't know if that has anything to do with the fact that we're pretty much fully VOIP as our normal course of business these days -- all our phones are shipped with VOIP defaulted to on (it's got some weird branded name in the settings but it is VOIP), and we've been aggressively phasing out non-VOIP-capable older phones over the past two years I've been here. Now that I think of it, that might be relevant.

Edit: Also, I mean, the proprietary smartwatch is very much targeted only at "your kid is too young for a real phone yet and also might get kidnapped" and "your elderly relative would get scammed if they could get calls or texts from strangers, also if they have Alzheimer's you can find them when they wander off". For customers who are... responsible enough to have fully-functional smartwatches, we just sell the Apple Watch and Samsung Galaxy Watch models.

Edit edit: For a while there, the fully-functional smartwatches were available only as add-ons to a phone line, they couldn't take calls on their own cellular number and be your only "phone". Apple Watch has recently rolled out the ability to be standalone again, which makes it a competitor to the proprietary smartwatch. We only just launched the non-kiddie-branded eldercare smartwatch around the same time, so I suspect we were trying to fill a niche with that which no longer needs filled, although granted the proprietary watch is a fuckton cheaper than an Apple Watch.
