Mobile phones these days can cost a fortune and it's no joke if it gets lost or stolen. The security number is a vital way to get your phone disabled, should this happen.

To obtain the security number press (star,hash,zero,six,hash) into your mobile, your security number ( 15 didgits ) will then appear on screen. Just make a note of it then you can let your network provider know immediatley the "dastardly deed" has taken place and your phone will be disabled.

Hope this is of help to you.
