How to change the SIM PIN

Order is not among your main virtues. Actually, you’re a pretty messy guy. In fact, every time you have to retrieve a document or an object that you don’t always have at hand, you go into crisis because you don’t remember where you put it. I guessed it, right? So let me give you some advice from a friend: before throwing the card with the unlock PIN of your new SIM and consequently losing it somewhere, change the code in question with a personal one that you are sure to remember!

How do you say? Did you have no idea that you could change the SIM PIN? Yes, and you should also know that it is child’s play! Whether you have an Android smartphone or an iPhone, all you have to do is access the device settings, activate the card lock with a code, enter the current PIN of the latter and choose a custom code to be used in the future to unlock the card. same.

Once the code is changed, it will be stored on the card and used on all devices where you install the SIM, so try not to be the usual messy and set a PIN that you are sure to remember (or otherwise pin it in a safe place). Understood? Well, then let’s not get lost in chatter anymore and let’s see immediately how to proceed using all the most popular smartphones at the moment.

Preliminary information

Before getting to the heart of the guide, explaining how to change the SIM PIN, it seems right to provide you with preliminary information about the code in question and its usefulness, in order to allow you to have perfectly clear ideas about it.

In case you don’t know, the PIN (acronym for “Personal Identification Number”) is a numeric password consisting of four digits. It is generated randomly by the telephone operator to which the SIM belongs, but the user can modify it to his liking later, by modifying the mobile phone settings.

To find out which PIN has been assigned to your card, just take a look at the SIM card. It is typically shown under a silver patina that can be removed using a coin.

The purpose of the PIN is to block the SIM avoiding unauthorized access to its content and features, therefore to the phone number, the network and the information saved on it, such as contacts and SMS.

If a wrong PIN is entered more than three times in a row, the SIM referenced by the code is blocked for preventive purposes. However, this does not mean that the mobile phone is also blocked. Blocking the SIM, in fact, only implies the impossibility of using the services associated with it, but the phone continues to work without the slightest problem.

How to change the SIM PIN on Android

At this point, I would say we can finally get to the heart of the guide. To begin with, let’s find out how to change the SIM PIN on Android.

To begin with, you must access the System Settings by touching the relevant icon (the gear icon ) located on the home screen or in the screen with the list of all the apps installed on the device, select the Security item or the Security and fingerprint item and choose the option SIM lock settings from the screen that opens.

Now, if it is not already active, move the lever relating to the SIM Lock function to ON, enter the current PIN of your card and confirm by pressing the OK button. If you have a smartphone with dual-SIM support, you can choose which SIM to operate by selecting one of the cards at the top or by choosing the appropriate item from the system menu.

Once the SIM lock is activated, you can proceed to change the code. Then tap on the Change SIM PIN item, enter the current PIN of the card and press the OK button, then enter the new PIN to be set on the SIM, press the OK button, enter the code again and confirm by tapping the OK button again.

If you are using a device that has a customized version of Android installed, you may need to follow slightly different steps to change the SIM code.

To give practical examples, if you want to change the SIM PIN on Huawei and your device is equipped with the EMUI interface, you need to access the Settings menu of the device, go to the Advanced settings> Security> SIM lock settings section and activate, if not already, the Lock SIM option. Then enter the current PIN of the card, confirm by pressing the OK button and proceed to change the code by tapping on the item Change the SIM PIN and entering, in sequence, first the current PIN of the SIM and then the new PIN you want to use for the latter two consecutive times.

If, on the other hand, you want to change the SIM PIN on Samsung, you have to go to the System Settings menu, then you must select the Lock screen and security item and reach the Other security settings section > Configure SIM PIN. In the screen that opens, if it is not already active, move the lever relating to the Lock SIM card function to ON, enter the current PIN of the card and confirm by pressing the OK button. Then, choose the Change SIM card PIN option, enter the new PINyou want to associate to the SIM twice consecutively and save the changes by tapping the OK button.

If you then want to change the SIM PIN on Xiaomi, you need to reach the Settings menu, then the section Password and security> Privacy. Then you have to press on the name of the telephone operator present at the top and move to ON, if you have not already done so, the lever next to the item Lock SIM, then you must enter the current PIN of the card and confirm the thing. Then, select the Change SIM PIN option, enter the new PIN you want to associate with the card twice in a row and save the changes you made.

Done! Now you have changed the unlock code of your SIM, which will also be changed on other phones in which you will eventually insert the card. Since it wasn’t that hard ?!

If after changing the SIM code you want to remove the PIN request when turning on the smartphone, go back to the Android Settings menu, select the items relating to the security and PIN of the SIM, move the lever relating to the Lock SIM card function to OFF and enter the card code in the screen that opens.

How to change SIM PIN on iPhone

If you have an “iPhone by”, you can change the SIM PIN on the iPhone simply by tapping on the Settings icon (the one with the gear ) located on the home screen and/or in the App Library and selecting the Cellular item and then SIM PIN.

In the screen that opens, if it is not already set to ON, you must activate the lever relating to the SIM PIN option, then enter the current PIN of the card and press the End button located at the top right.

Once the SIM PIN request is activated, you can move on to changing the code. Then tap on the Change PIN option, type the current PIN of the card and press the Finish button located at the top right.

After this step too, type in the new PIN you want to associate with the SIM, press the Finish button at the top of the screen, type the new PIN you want to use for the card for the second consecutive time and confirm by tapping the Finish button.

Mission accomplished! You have finally managed to change your SIM unlock code, which will also be changed by inserting the card in other phones.

If after changing the SIM code you want to remove the PIN request each time the phone is turned on, go back to the Settings> Phone> iOS SIM PIN section, move the SIM PIN function lever to OFF and enter the card unlock code.

In case of problems

Trying to change your SIM unlock code, have you entered an incorrect PIN three times in a row and now you find yourself with an unusable phone? Don’t panic! If your smartphone got stuck after entering an incorrect PIN, you can remedy the situation by entering the card’s PUK.

If you have never heard of it, the PUK (acronym for “Personal Unblocking Key”) is an 8-digit code which, if entered, allows you to unlock devices that are blocked after entering an incorrect PIN three times consecutively.

You can find the PUK code of your card directly on the SIM card or, alternatively, by contacting your telephone operator, proceeding as indicated below, although not all telephone operators allow this.

• If you are a TIM customer, you can try to call 119 and ask an operator to communicate the PUK to you (after providing them with your personal data, your identity card code and other information that may be requested). However, I warn you, the outcome of the operation is not taken for granted, since the company rules prevent TIM operators from providing private information such as the PUK code of the SIMs.
• If you are a Vodafone customer, you can access your personal area on the Vodafone website and retrieve the PUK by selecting your phone number. Alternatively, you can try to contact 190 and ask an operator to provide you with the PUK code (after having communicated all your personal data to them).
• If you are a WINDTRE customer, access the customer area of the Wind website, select your number and click on the item to retrieve the SIM PUK. Alternatively, download the WINDTRE app for Android or iOS, log in with your account data and tap first on your number and then on the line information item. Alternatively, you can try to contact 155 and ask an operator to provide you with the data of your interest (after having communicated your personal information).
• If you are an Iliad customer, access the personal area on the manager’s website, select the item My personal data from the sidebar and press the Click here button that you find under the heading My PUK code. Alternatively, try contacting 177 and ask an operator to provide you with the PUK (after providing your personal details).

If any step is not clear to you and/or you want more information on the practices described above, I invite you to read the tutorial I have dedicated specifically to how to recover PUK code.

If, on the other hand, you have already tried to unlock your device by entering the PUK, but you have failed by sending the SIM in block (which happens after 8 wrong attempts), you just have to contact your operator and request a new SIM. To speed up the process, I recommend that you go directly to a physical center of the operator – equipped with a blocked SIM, identity card and tax code – and request the new card on site. You can then start the procedure for transferring the remaining credit from the old to the new SIM.
