# MS - Mobile Station

**MS - Mobile Station**

A Mobile Station (MS) refers to a wireless device used for communication in cellular networks.

It comprises both the mobile equipment (ME), such as a smartphone, and the subscriber identity module (SIM), which stores user-related information and authentication data. 

The MS allows users to make calls, send texts, and access mobile data services.
