Re: And jolly useful it is too....???
... an esim will be much more easily hacked if it's incorporated into the OS ...
Is wouldn't (shouldn't) be done by the OS.
To be secure an eSIM needs to have dedicated secure storage hardware in the device. Provisioning the eSIM would need an encrypted exchange whereby the carrier sent sensitive data to the device, and the device stored the data in a protected area of the phone. The supplier of the device would have to be involved in this exchange in order to enable the device to write the data to the secure area.
I can't see the hardware vendors and the carriers actually getting their acts together sufficiently well to enable this to happen, though.
