The value 72499 appears for the CBC on iPhone

Here on the 4G Network, we are looking at cases where the value 72499 appears on the CBC on iPhone. We know that in a RAN Sharing network, 724-99 is the first PLMN of the site, and they call it DUMMY. The eNodeBs are Nokia. Does anyone know how to solve this, and also why this? Thank you and have a good day.

Is this happening in the entire Nokia LTE area, or just some eNodeBs?
