Only give your phone number out to people that you want to have it. You can hide your number by setting it to 'private' in the settings of your phone, but there's an even easier way - dial 1831 before you call.
For example, if you wanted to call 02 9870 2200, but didn't want the person on the other end to see your number, you should ring 1831 02 9870 2200 instead.
(This works when you're ringing from and to a mobile or a landline phone! This has been tested in Australia, there may be another prefix you should dial elsewhere in the world)

If you've got bluetooth switched on, on your mobile phone, and your phone is not set to 'hidden', chances are you're open to bluejacking, bluesnarfing or bluebugging. What does this mean? Read on below.
Bluejacking - the sending of unwanted messages from one bluetooth device to another. While bluejacking is normally harmless, often people who receive these types of messages don't know what has happened, and may think that someone has taken over their phone.
Bluesnarfing - the unauthorised access of information from a wireless device (such as a mobile phone) through a bluetooth connection. By 'hacking' into the phone, someone can have access to the calendar, pictures, contacts, text messages, and any other content stored on the phone.
Bluebugging - another form of bluetooth attack, in which someone takes control of your phone, to call their phone. This means that someone can simply listen to any conversation their victim is having in real life. Further development of bluebugging tools has allowed users to totally take over their victim's phone, making calls and sending text messages from the victim's phone.
By turning off bluetooth when you're not using it, and/or by setting your phone's bluetooth settings to 'hidden', you can remove the risk of these threats.
Recent studies and anecdotal evidence have demonstrated that the majority of teenagers leave their mobile phones switched on while they sleep. Why is this? There seem to be many reasons, such as teenagers not wanting to 'miss an important call'.
If you leave your mobile phone on in the middle of the night, there's nothing to stop someone unwanted from calling you. By switching your mobile phone off when you go to sleep, you don't have to worry about phone calls, text messages or reminders interrupting your sleep. If someone unwanted does call you in the middle of the night, and your phone is off, you're likely to get the message in the morning, when friends and family are awake and around to help you take action.
If you MUST keep your mobile phone on in the middle of the night, consider using 'block lists' or 'allow lists' on your mobile phone, so that only phone calls from people that you specify can get through.
It's a good idea to set a PIN on your SIM card, and a PIN on your phone too, if your phone allows it.
If you set a PIN on your SIM, whenever you start up a phone with your SIM card in it, the mobile phone will ask you to enter the PIN. This means that someone has to know your PIN in order to use your mobile phone number, or access text messages and contacts stored on your SIM card.
If your phone allows it, you should also set a PIN on your mobile phone. This stops someone else from using their SIM card in your phone, without knowing what your PIN is.
It's also a good idea to record your IMEI number. This is like the serial number for your phone, and can be used to help trace your phone or prove that the phone is yours, if it is lost or stolen. Find your IMEI number by looking underneath the battery, or by dialing *#06# (asterisk, hash, zero, six, hash)
