How to disable the password on SIM-Xiaomi map: The full guide

Many users of Xiaomi, Redmi and Poco smartphones face a situation where every time the device is turned on or rebooted, the system insistently requires input. PIN-It's a standard security feature designed to protect your SIM card from unauthorized use in the event of a phone theft, but if you're always in your possession, constantly typing numbers can be annoying and take precious seconds.

Disabling this request is a simple process, but it requires care, because it is working with system security settings. SIM-The card increases the risk of losing the device, but it greatly simplifies the daily use of the smartphone. In this article, we will discuss in detail how to remove the password, what are the nuances of the interface. MIUI What to do if the code is forgotten.

Before you start making changes, make sure you know the current one. PIN-The security system will not allow you to disable the protection or change the settings without prior authorization. If you have never changed the factory settings, the default code is often listed on the plastic card that came with the SIM card, or specified in the contract with the operator.

Why do you need it? PIN-The code and whether it is possible to ignore it

PIN-Personal Identification Number is a digital key stored on a SIM card chip, which is designed to block access to a mobile operator’s network when you try to use the card on another device without the owner’s knowledge. Many users perceive this request as an unnecessary obstacle, especially when you need to urgently answer the call after turning on the phone.

You can ignore this level of protection, but you have to weigh the risks, and if you lose your phone, an attacker can extract the SIM card and insert it into his device, gaining access to your calls and, more importantly, to your phone. SMS-The codes for confirming the login to banking applications and instant messengers. Modern two-factor authentication makes it possible to use the same code. SMS Critical element of digital profile security.

On the other hand, for a second phone or device that is only used for calls within the home Wi-Fi, turning off the password is perfectly justified, eliminating the need to remember an unnecessary combination of numbers, and the decision to disable or leave the protection is a personal choice, based on the balance between convenience and security.

⚠️ Attention: Disable. PIN-code, you only remove protection from the SIM card, and this does not affect the locking of the screen of the smartphone itself (pattern lock, fingerprint or Face). ID), which continue to operate in the normal mode.

Preparing for changes in security settings

Before you go into the depths of the menu, you need to do a little training, which will help you avoid unforeseen blockages and loss of access to communication. PIN-The code that's installed now. Without it, the system won't allow you to move to parameter management.

It's also worth having on hand. PUK-This is a unique unlock code that you need if you type three times incorrectly. PIN-- The code. PUK printed on the same plastic card as the original PIN, Or you can find it in the operator's personal office, write it down or take a picture just in case.

Make sure your Xiaomi battery is strong. Although the process takes a minute, suddenly turning off your phone while writing down your SIM chip settings could theoretically cause a failure, although current power and memory controllers minimize this risk.

If you use two SIM cards, you have to repeat the procedure for each of them separately. Security settings in Android and the MIUI shell are stored independently for each slot. This means that by disabling the password on the first SIM, you will not automatically turn it off on the second SIM.

Step-by-step instruction: shutdown PIN-Xiaomi code

Interface. MIUI It may vary slightly depending on the version (MIUI 12, 13, 14 or HyperOS), but the logic of the menu remains the same. SIM-Follow the algorithm carefully by reading the names of the items.

First, open the main menu and find the Settings app (the gear icon). At the top of the screen, you'll see the search bar, which is the fastest way. Type in the word "SIM" or "password" and the system will suggest you go to the desired menu section, which will save time on wandering tabs.

If you don't search, you can do it manually. Go to Passwords and Security. In some firmware versions, this item may be simply called "Security" or be inside the "Advanced" menu. SIM-map».

In the list that opens, you'll see your SIM cards. Click on the one you want to unplug. Usually, there's a "Request" switch. PIN-code" or "Change" button PIN-We need to control the request. When you switch the switch to off, the system requires you to enter the current one. PIN-code.

• 📱 Open the “Settings” of the smartphone.
• 🔒 Go to the section "Passwords and security».
• 📡 Select “Privacy” or “Protection” SIM-map».
• 🔢 Enter the current one. PIN-code.

After successfully entering the numbers, the switch will change color (usually gray), which will mean deactivating the protection. Now, when you reboot, the phone will no longer ask for the code. Check the result by rebooting the device: Settings → About the phone → Reboot or holding the power button.

What to do if you've asked PUK-code

When the phone is required to PUK-The code is in two cases: you have forgotten. PIN and got it wrong three times, or the SIM card was removed and inserted into another device with the protection turned on. PUK-Personal Unblocking Key is a master key that cannot be changed or re-chosen.

Unlike in the PIN, changeable, PUK It's given once and for all. It can't be changed through the phone's settings. PUK-code is incorrect 10 times, the SIM card will be permanently blocked and cannot be restored - you will have to go to the operator's cabin for a new one.

Where to find this code:

• 📄 On a plastic card holder you received when you bought a SIM card (often hidden under a protective layer).
• 🌐 In the personal account on the website of your mobile operator (section "Fares and services" or "My SIM cards»).
• 📞 Calling the operator’s support service from another number (you need to call the passport data of the owner).

Once the code is found, enter it in the field on the lock screen, and then the system will prompt you to come up with a new one. PIN-If you want to disable the request right away, select the cancellation option or install a simple code (such as 0000) and then disable it according to the instructions above.

⚠️ Attention: Never enter PUK-You only have 10 attempts, and after you run out of limit, the SIM chip burns down software, and no recovery software can help.

Shift. PIN-more convenient

If you don't want to give up security entirely, but the current code is too complex or inconvenient, you can change it. This is true if you use a standard carrier code (like 1111 or 1234), which is easy to guess. Replacing it with a unique combination will increase the protection of your data.

The change process is similar to the shutdown. → Passwords and security → Protection SIM-Select the item "Change" PIN-First you have to enter the old code, then twice new, come up with a combination that is easy to remember but difficult to match (for example, part of a phone number or a date not related to a passport).

Using standard codes like 0000, 1234, or 1111 is bad practice, and these combinations are tested by hackers first when they try to break into them, and a unique 4-8 digit code that has no obvious sequence will be a reliable barrier.

Remember that when you change the code, the old one stops working instantly. If you forget the new code immediately after the change, you will have to use PUK. So be careful when you enter the new combination for a second time for confirmation.

Comparison of SIM card protection methods

The table below compares the different SIM card security states, which will help you choose the best use case based on your habits and level of paranoia about data security.

As you can see from the table, giving up your password completely is convenient, but it leaves you vulnerable. PIN-The middle ground is the use of non-obvious but memorable code.

The optimal balance is the setting PIN-code other than the standard (1234/0000), But you'll never forget, and you'll only allow full deprotection for second devices.

Frequent problems and their solutions

Sometimes, users find the phone "glutting" and requesting the code again, even if you just turned it off, this can be due to a system cache or a SIM card reading error. Try extracting the SIM card, erase the contacts with a pin and paste back.

Another problem is that there's no menu item. Some custom firmware or older Android versions may have different paths. Look for Mobile Networks or Network and Internet. At the very least, search for settings by typing in "SIM."

If the phone says "SIM card locked" right after you turn it on, even though you've disabled the password, it may have worked after several failed attempts to enter earlier. PUK-Also check if the Fixed Set feature is enabled, which can block outgoing calls by requiring code.

⚠️ Note: If you inserted a SIM card into another brand’s phone (such as Samsung or iPhone) after Xiaomi, the security settings are saved on the card itself. PIN You will have to re-introduce the menu of the new device.

In rare cases, network resets help. Go to Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. This action will not delete your personal files, but will return network settings to factory values, which can eliminate software conflict.
