Are you sure? Simply go to settings > mobile data, and turn off the switch.

Welcome to Android Central! What do you mean by "still showing mobile data enabled mode not in bright color (light color)"? Do you mean that the mobile data signal indicator (e.g., 3G, 4G, LTE, etc.) in the status bar still shows up, but it appears greyed out rather than bright white?
