Mobile phones now do so much more than simply make calls that many of us would be completely lost without them.
Unfortunately thousands of phones do go missing each year and many of these will have been stolen.
But if your phone does go missing you could be left with a much bigger headache than simply having to replace your handset.
Not only are many smartphones worth hundreds of pounds, but thieves can quickly rack up huge bills on stolen phones.
You may be liable for all charges run up on your phone when it goes missing up until you report it as lost or stolen to your provider. Therefore, it's important you contact your provider as soon as possible to avoid facing high charges as a result of unauthorised use.
If your phone goes missing and you are with Three, Virgin Mobile, Vodafone, EE or O2 for mobile services, you should only be responsible for paying up to a maximum of £100 for any unauthorised usage outside of your allowance- if you report your phone as missing within 24 hours.
If you are with Vodafone and you miss the 24 hours but report your phone as missing within five days, you should only be responsible for paying up to £500 for unauthorised usage outside of your allowance. See the Government's announcement here
Always treat your phone as carefully as you would your bank or credit cards.
Take care when using your phone in public, don't let it out of your possession. Make sure you put a passcode on both your handset and SIM to make it more difficult for thieves to use.
These video guides show you how to do this on some popular handsets.
