Ignoring the security settings offered by the mobile devices we can access today is without a doubt one of the worst mistakes we can make when configuring a device. Setting up a screen lock, using an unlock pattern and using a fingerprint not only increase the security of the device, but also prevent anyone from easily accessing our data.
While these settings are easy to access and anyone can configure them from scratch, there are other rather hidden sections that require our attention to prevent our personal data from being accessible in case of theft or loss. A clear example of this is the SIM card PIN , a code that is not usually changed and that could cause us to have a very bad time.
From a security perspective, changing the PIN should be mandatory , because if the SIM card is inserted into another mobile device, passwords can be recovered and messaging platforms can be accessed quickly and easily.
Fortunately, all mobile device manufacturers allow you to change the SIM card PIN without too many complications. Speaking specifically about Xiaomi, Redmi or POCO mobiles, you don’t need to be a technology expert to access the section from which you can carry out this action.

How to change PIN code on a Xiaomi, Redmi or POCO mobile?
If you have a Xiaomi, Redmi or POCO phone and you want to change the PIN to avoid future problems, you will not need to contact official support, or the mobile operator that provided you with the SIM card associated with your phone number.
By following the steps below, you can change your PIN in the blink of an eye. However, it is important to note that all SIM cards are “blocked” by default, meaning that mobile phone operators enter a default PIN , which will be requested by the mobile phone when you try to change it.
Most mobile operators use the code “1234” on all SIM cards, so changing it should be a mandatory task. However, sometimes this PIN is different, so in such cases it is necessary to request this code using the contact numbers of the telephone operators .
Change PIN on Xiaomi, Redmi or POCO with MIUI
The various updates that this Android-based customization layer has received have been quite “cruel” to users, as MIUI has increasingly hidden the section that allows increasing the security of the SIM card .
Whether you want to disable the PIN code request or change it to improve its security, you must follow each of the steps that we are going to show you below (this tutorial works on all mobile devices that have MIUI inside).
- The first thing you should do is access the terminal Settings.
- You must click on the option that says Password and security .
- Therefore, you will have to scroll down to the Privacy section and enter it .
- Then you will have to choose the SIM (you could have more than one if your terminal supports two SIM cards).
- Within the security section of the card, you will see various options. You will have to pay attention to the one that says Change SIM card PIN .
- You will need to enter your current PIN (which should be “1234”).
- And finally, you will have to enter the new PIN you want to use.
In case the steps we have shown in the tutorial do not work for you, you will be forced to update MIUI to the latest version (from the settings of your mobile device).
Change PIN on Xiaomi, Redmi or POCO with HyperOS
On the other hand, if your phone has been updated to HyperOS , you can find the function that allows you to change the PIN by following all these steps:
- First you will need to enter your phone’s Settings .
- Then you will have to click on Fingerprints, face data and screen lock .
- Therefore, you will need to choose the option that says Screen Lock .
- You will have to enter the section called Privacy (you will have to scroll down the screen until you can find it).
- You will need to look for the More security settings option . Once you have found this option, you will need to click on it.
- Then you will have to choose the SIM card .
- You will have to tap on the option that says Change SIM card PIN .
- Your phone will ask you to enter the current PIN (should be 1234).
- You will need to enter the new PIN twice in a row.
- Once you have changed the PIN, you will need to confirm it by clicking on Confirm .
If you followed all the steps correctly, you will have changed the SIM PIN on your Xiaomi, POCO or Redmi mobile phone with HyperOS.
Change PIN on Xiaomi with Android One
If your phone has the famous Android One inside, the security options will be located elsewhere . Being an operating system created specifically for low-end terminals, there are settings that are much more hidden than in MIUI and HyperOS. Likewise, you can find the function that allows you to change the PIN by following these steps:
- The first step you will have to take is to enter the operating system Settings .
- Once inside those settings, you must click on the option that says Security .
- Therefore, you will have to enter the section called SIM card lock .
- Next, you will need to tap on Change SIM card PIN .
- Your Xiaomi mobile will ask you to enter the current PIN (this PIN is usually 1234).
- You will then need to enter a new PIN (twice in a row).
- You will need to confirm the PIN code change.
- If you have performed all the steps correctly, you have successfully changed your SIM card PIN.
Important! Don’t lose your PIN
Unlike other security codes, the SIM PIN cannot be easily recovered , so losing or forgetting it is a “death sentence.” We recommend that you write down the PIN using a password manager , use a pen and paper, or store the code in a Notepad on your computer.
When you change your phone and insert the SIM card, the phone will ask you for the PIN code that you entered when you changed it on your Xiaomi, Poco or Redmi mobile device. If you do not have this PIN code, you will not be able to connect to the 4G or 5G network, nor will you be able to log in to your account on WhatsApp, Telegram and other messaging applications.
