A PIN code: what is ?

First, Pin is the English acronym for personal identification number. It can be translated into French by personal identification number. If we are based on this development, the PIN code can be defined as a number to identify a person. However, it takes something even more important.

Concretely, the PIN code corresponds to a code composed of 4 digits. It is associated with a SIM card and works as a password that allows you to unlock it. When the SIM card is inserted into a phone, when it starts, it will require the PIN code, otherwise the device will remain inaccessible.

By default, the PIN code of a new SIM card is often defined to 0000. However, in some operators, we prefer to put the code 1234 by default. In both cases, this PIN code is to be changed when you receive the SIM card and start using it.

Indeed, the PIN code is used to protect access to your phone and SIM card. It helps to protect your personal data from indiscreet people. This code will also protect your data if you are ever stolen your phone. When it started, it will not unlock without this famous PIN code.

There is also what is called PIN 2 code 2. Its role is the same as for the PIN code just. Only, this second code is used to secure more specific features such as photo gallery, directory, messages, etc.

How to change the PIN code of your SIM card ?

Configuring a PIN code on your phone is not compulsory. Nevertheless, it is recommended if you want to establish a minimum of security on your device.

It must be changed and choose a safer code. A 4 -digit combination that no one can guess. In any case, you will have to avoid choosing your date of birth.

Once you have found the right PIN code, just go to the “Security” tab of your phone settings to modify it. Do not forget to note it somewhere. You may not remember if you are one of those users who never turn off their laptop.

If you think a person knows your current PIN code, immediately change it in your phone settings. It is possible to modify it as many times as you want if the security of your personal data or your services is threatened.
