# Cell Id

**PLMN Cell ID**

PLMN (Public Land Mobile Network) Cell ID is a unique identifier used in mobile telecommunication networks. 

It combines the PLMN code, which identifies the carrier's network, with the cell ID, which identifies a specific cell tower within that network. 

This identifier plays a crucial role in mobile communication, helping in tracking and managing connections across the network.
