Bluetooth is a wireless technology than can allow you to communicate with a number of devices such as computers, keyboards and PDAs without the need for any cables. Bluetooth headsets are also available for cell phones, so that you can talk hands free when you are driving or typing on your laptop, and also allows you to synchronise information between various different devices.

However one problem with Bluetooth is that when it is enabled it does mean that other unscrupulous people with Bluetooth capabilities can actually access your device and interfere with your information in a number of ways:

• Bluejacking – this is when people send unsolicited emails and messages to other Bluetooth devices, and although it is normally harmless this can provide a backdoor for fraudster to access your phone and take it over without your knowledge.
• Bluesnarfing – this is when a fraudster uses your Bluetooth connection to get into your cell phone or PDA to gain access to the personal information it contains such as your diary, calendar, text messages, contacts list etc…
• Bluebugging – this is when your phone is taken over completely by another person via the Bluetooth connection, enabling them to listen in to you conversations, intercept your text messages and emails and use your phone to make their own calls and text messages.

You may find that your battery needs charging everyday, and if you are out on the move and using the phone heavily you may be concerned about running out of battery before you can get it charged again.  There are a few simple ways to prolong the life your cell phone though, and these can save you a lot of worry:

• Some cell phones are pre-set to ‘Enhanced Full Rate’ (EFR), which means they drain the battery quicker because of top level screen and applications settings.  You can turn this off so that the phone is running on lower settings, and this can save the battery from draining so quickly.  Check your instruction manual for how to amend the EFR setting.
• Turn Off the Backlight – this is only really necessary at night, so keep the backlight turned off during the day to save battery power, and also change the default setting so that the light goes off after 5 seconds of inactivity for when you do use it.
• If you know you are not going to use your phone for an hour or more, then just turn it off.  It will still receive messages and update the call list for you, so you will not be completely out of the loop, and you can just get back to anyone who leaves a message when you turn it on again.
• Limit the amount of non-talk functions you use your phone for such using online features and camera functions, as these use a lot of power, and can drain the battery low in just a few hours.

You probably take your cell phone everywhere with you and keep it on your nightstand when you are sleeping, and you may also keep lots of your own personal information in the memory such as your friends and co workers contact details, and any notes, reminders and appointments.  Therefore it is important that you guarantee the privacy of your cell phone, to avoid any unwanted calls or phone hijacking.

Restrict Your Number

Only give your phone number to people who really need it, and never publish it online.  You can also set up private caller ID so that the person who you are calling cannot see your number by going into the call settings and selecting ‘private’ option, or on most phones you can simply dialling 1831 before you input the number you are calling (this works when you are ringing either another cell phone or a landline number).

Allow Lists

Your phone will have an option to block calls from people you do not know, and you can do this by going into your ‘allow lists’ and inputting only your friends and family’s numbers.  If you don’t want to restrict your phone quite so much you could use the ‘block’ function instead, which will only block those particular numbers you do not want to call you.
