Mobile phone security

Think smart about mobile phone security

No one wants to think about losing their phone, but taking some precautionary measures may help in the even of loss or theft.

Unfortunately, hundreds of thousands of phones do go missing each year, many of these are subsequently found by the owner. However according to Home Office crime survey data there were over 500,000 victims of mobile phone theft last year.

If your phone does go missing you could be left with a much bigger headache than simply having to replace your handset. Importantly registering your device increases the chances of it being identified and returned.

Mobile Phone Registration

When a mobile phone handset is made it is given a unique electronic serial number known as the International Mobile Equipment Identity (IMEI). This number is usually 14 to 18 digits long. It can also be displayed on the screen of the phone by entering *#06# into the keypad - This is the most important number you need to provide when registering it on the Immobilise National Property Register. 

How to get the IMEI information

Provide the basic details

When registering your phone on your immobilise account provide the;

  • IMEI number,
  • the serial number,
  • its make and model information.
  • Take a photo and;
  • write a description of the item and any distinctive features.

Contacting your network

If you’re on a contract and you lose your phone or it’s stolen you should report it to your mobile phone provider immediately - within 24 hours. The network operator will be able to block the phone and render it useless, even if a new sim card is used.

EE, O2, Three, Virgin Media and Vodafone have signed up to a £100 'liability cap', which means you'll only be liable to pay for the first £100 of your phone bill if your phone is lost or stolen. But the cap is only activated if you report your phone as lost or stolen within 24 hours of it going missing.
