Operator name in the iPhone disappeared after updating to ios12?

After the update to iOS 12.1 both the iPad and the iPhone, the operator name on the top left has disappeared.

That makes me really angry because this ad is extremely important to me. Is it possible to show the ad again?

If not, I immediately sell all devices and get a Huawei because the ad has top priority for me.

You just have to swipe down from the top left (corner) … Then you see it in the corner on the top left!

Since only the message center opens. The operator name is not displayed anywhere.

That would be really awesome, if this annoying operator logo would be gone, but have not yet installed 12.1.

If necessary, you can also just look in the settings

The operator logo is stored on the SIM card. Some third party maps never show this.
Presumably your operator still has to provide a corresponding update for iOS 12.1.

That is not right.

But.
