spiral I can confirm you can install multiple (I tested 2 so far) eSIMs in addition to the physical SIM. You can switch between SIMs as you wish, there are only a couple of caveats:
- To be able to switch between eSIMs, sandboxed play services need to keep running in the Owner profile. So if someone hoped to install Play Services, install extra eSIM and uninstall Play Services that won't work because for switching between eSIMs you also need Play Services
- Enable Privileged eSIM management checkbox in Settings get disabled automatically on each reboot, so you need to go in Settings and enable it each time you need to switch between eSIMs (if you rebooted since the last switch)
Now I wonder if there is a limit of how many eSIMs can be installed on Pixel 6 Pro?
