To activate, key is *3370# your mobile will restart with this Reserveand your instrument will show a 50% increase in battery. This Reserve will get charged when you charge your cell next time.
2). The Emergency Number worldwide for Mobile is 112. If you find yourself out of coverage area of your mobile network and there is an emergency, dial 112 and the mobile will search any existing network to establish the emergency number for you.
