In today's advanced society, the mobile phone has become one of the necessities of life. Nowadays, it is difficult to find anyone who does not have at least one mobile phone line along with a mobile phone handset. In fact, the mobile phone has become an office and an information bank, and important information such as private text messages, the addresses and telephone numbers of different people, bank account numbers and their passwords, family photographs, and many other things are stored in it. In order to protect this important information, the owner of a mobile phone must observe important security points, some of which are mentioned below:

1. Having the serial number and the information-deletion code
Every mobile phone has its own special serial number. This number helps a person, in addition to making sure the phone is genuine by visiting the official website of the mobile phone's manufacturer, to take action through the judicial authorities to find the phone if it is lost or stolen. One of the ways of obtaining the serial number of a mobile phone for some handsets is to

enter the keys * #60# in order and then press the green key or the call key.

This number is specific to your device. When your mobile phone is stolen, you can contact your network provider and give them this code. They will then be able to block your mobile phone. It is possible that a person may not be able to get their phone back, but this mobile phone will no longer be functional, and another person will not be able to use it even if they change its SIM card.

2. Location
Some mobile phones are designed in such a way that some of their components automatically inform the mobile phone service provider of your current location. In addition, some mobile phones are equipped with a GPS system, and this precise information may be embedded in other data in photographs, text messages, and Internet searches carried out through the mobile phone.

3. Password-protecting the phone and SIM card
Most mobile phones on the market have an option in their settings for choosing a password to protect what is recorded on the phone and in its memory. By password-protecting their mobile phone, a person in fact makes access impossible for other people. This password can be a number, a word, a combination of the two, or even an image. It is also possible to password-protect SIM cards on the market. In the mobile phone's settings, by activating the SIM card lock or PIN code, one can prevent other people from using the device.

4. The most insecure protocol
One of the additional features of most mobile phones is Bluetooth; however, Bluetooth is one of the

most insecure communication protocols in

the world. In fact, the advantage of Bluetooth is that one can easily connect to another phone without a wire and transfer information, and if the user knows how it works, they can make use of its features. This technology transfers information within a radius of 10 meters between any devices, such as mobile phones, laptops, and tablets. At the same time, your Bluetooth connection may be hacked; that is, when your Bluetooth is on and you are transferring information, a hacker may take advantage of the opportunity and

easily gain access to your mobile phone. This situation is also conceivable when Bluetooth is on but you are not using it.
Therefore, it is recommended that you turn Bluetooth off when you are not using it, or when you are talking on the phone or entering personal information into the mobile phone. If you want to use Bluetooth, establish your connection to the other phone with a long and more secure password.

5. Encryption for important information
Mobile phones can usually store important information in their memory. This information may include photographs, video clips, text files, telephone call histories, information about people saved in the phone list, and personal information about the owner of the mobile phone. Protecting this information is difficult and at the same time important and necessary. For this reason, the choice of a mobile phone is of particular importance; therefore, try to choose a phone that has the ability to encrypt different sections of information.

6. Having a backup copy
Despite their countless advantages, modern technologies are not always reliable; perhaps it has also happened to you that you have lost all the information stored on your mobile phone for various reasons, including losing the phone or its breaking down.

Usually, a professional user has a backup copy of all the information on their mobile phone. Various kinds of backup software are available on the Internet. Some mobile phone companies also provide software for backing up information on their websites for download.
