Unable to make or receive calls on iPhone X

My I Phone X intermittantly suddenly won't either make or receive a call, then just as suddenly it will work once more. Sometimes turnin aeroplane mode on and off again will help, not always. I have checked out all forwarding, call waiting ect. all seem to be as they should be, but still the problem persists. Has anyone got any idea what may be going on here?

That is your phone carrier's feature, report it to them.
