Caller id always on , where i want switch it back it’s just spinning wheel

That feature is controlled by carrier. Contact your carrier for issues with it.

What does this mean because i am having this probelm with turning my caller Id on and i only have a loading button. But what does your statement mean and where should i go to get it fixed?

It means contact your carrier support for help with caller id feature if it doesn’t work for you and/or you cannot turn it on/off.

Not all carrier allow for users to make changes to Caller ID on the iPhone itself. They control it on their end.
