Has anyone else noticed that Instant hotspot, where you turn on the personal hotspot on the phone from your iPad or computer, hasn’t been working if you have only an eSIM? I thought that maybe this update would fix it but it doesn’t appear so. I am also having trouble with handing calls off from my computer to the iPhone but i don’t know if that is eSIM related or not. It sometimes just doesn’t work.
Instant Hotspot hasn't been reliable in general for quite a few iOS versions now. Sometimes it works, sometimes it doesn't. It may be related to the phase of the moon, or how much fiber I've gotten in my diet lately. I don't even bother trying to fix it anymore and just manually connect now when it's not working.
So it may have nothing to do with eSIM, and more to do with which side of the bed you woke up out of this morning.
