I can't make or receive calls but SMS and internet works fine.
Sim in another phone has the same issue, different SIM in my pixel works fine.
Happening in all locations, 100% of the time. It has happened twice previously in the last month and on those occasions I've had a text from EE to say network settings have been updated and once my phone restarts the issue goes away.
Network settings have been reset which hasn't helped.
