OS 16 Upgrade Appears to Disable EE SIM

[EHR1]

Upon upgrading my iPhone 13 from OS 15 to OS 16, the EE SIM is no longer recognised. Error message: "Cellular Plan No Longer Available". What's the fix?

Thanks @EHR1.

I'd recommend contacting or Customer Care team about this so they can run through additional troubleshooting steps with you.

Thanks, Jon.  I worked with your Customer Care team by the EE chat function, which took hours!  I then visited an EE store to see if they could help.  Bottom line, there's still no resolution or way forward except to contact Apple and perhaps hope their next iOS update will fix the problem...but that's only my guess.  

Meanwhile, I'm re-engaging the Customer Care team, which is probably the third shift working with me!

My service is restored, not by anything I did.  Rather, by my third or fourth time engaging the EE Customer Care Tech team.
