That's more to do with the carrier than the eSIM standard or phone, though. My iPhone supports eSIM but my carrier (and the others, apparently) refuses to provision eSIMs for anything that isn't a smartwatch.

The eSIM worked just fine on the iPhone before.

Like I said -- more to do with carrier restrictions. Your carrier doesn't have Pixel 5 on the "allowed devices" whitelist, so when it sends a registration request via that eSIM the network rejects it. (Your carrier knows which phone model is attempting to activate a SIM, even a physical one, and can reject it for whatever reason. It's just less common)

My Pixel 2 supported WiFi Calling but my carrier didn't acknowledge it as "supported" and the carrier's servers refused to send it a settings file.

I assume that’s an autocorrect? I like it.

Yes. I meant physical sim.

Another thing that I just remembered is that my ISP only allowed me 10 activations on the e-sim before having to buy a new one for 50 bucks.
