Make emergency calls
In any country where digital GSM is used, you can make an emergency call if your phone is covered
by the network (you can know about this by checking the signal strength indicator bar at the upper corner of
the display of the cell phone). If your network operator does not provide roaming service in that area, the
screen will display "EMERGENCY CALLS ONLY", telling you that you can make this kind of call only. If
you are in the coverage of the network, you can make emergency calls even if your SIM card is not inserted
in.
* In some areas, the 112 (emergency call) service is provided by the network operator. If there is anything
abnormal, contact your network operator!
IMEI
International Mobile Equipment Identity. You can see the bar code label printed with this number at
the back of the cell phone after you have turned off the cell phone and removed the battery. This number is
also stored in the cell phone, and can be displayed by entering "*#06#" (without quotes) on the screen dial
interface.
