Always record your Mobile phone's serial number aka IMEI Number.
This is the unique number throughout the world to identify every handset
Key in the following digits on your phone:
* # 0 6 #
A 15 digit code will appear on the screen.? Write it down and keep it somewhere safe?
Should your phone get stolen, you can phone your service provider and give them this code.
They will then be able to block your mobile phone, and it will be totally useless, even if the thief changes the Sim card.
You probably won't get your phone back, but at least you know that whom ever stole it can't use it.
If everybody did this, there would be no point in stealing a mobile phone.
So please pass this message on to as many people as possible.
