Hypothetical situation:
iPhone XS Max has one line through a nano-SIM.
A second line with support for Apple Watch multi-SIM operation is added by activating an eSIM on the iPhone.
Apple Watch is set up through the iPhone and linked to the eSIM number.
Everything works as you'd expect - phone calls and messages to the second line come up on the Apple Watch.
The eSIM line is activated on a cellular iPad, causing it to be deactivated on the iPhone because it can be active only on one "real" device at a time.
Will the Apple Watch continue to have access to cellular network via the eSIM line, even though it's no longer active on the iPhone?
In other words, does the iPhone merely serve the purpose of setting the Apple Watch up?
