Mobile phones are stolen every day, mainly by opportunist thieves. Young people can be especially vulnerable. By taking a few simple steps you can prevent your phone going mobile without you:

  • Always be aware when you use your phone. Make sure you use it when and where it is safe to do so and be aware of those nearby.

  • Keep your phone out of sight in your pocket or bag when not in use.

  • Do not leave your phone on show in public places

  • Make sure your phone is marked and identifiable. Use permanent property marking techniques. Mark the battery, inside and outside of the phone.

  • Use your phone’s security lock code or PIN number.

  • Keep a record of the make and model number of your phone

  • Keep a record of your IMEI number, which is unique to your phone and can help you recover it. If you press*#06# on your phone its 15 digit IMEI number will be displayed.

Report a lost or stolen phone to the police as soon as possible, giving the mobile phone number, type of handset and IMEI number.

Please note that falsely reporting the theft of your mobile is a criminal offence for which offenders face prosecution for wasting police time and deception.
