That security mechanism is not all needed and there are many who want to remove the PIN from the SIM so as not to have to remember another number. This process is not complicated and is basically done in the same way on all mobiles, the only thing we must do before completing it is to know the code for the last time. Then we recommend you leave this and the PUK written down in the box of the smartphone, in case for some reason you have to use it again.

On Android phones

On Android devices the process to remove the password or PIN from the phone card begins in these settings, and then go to the security section. Once inside, we have to click on the lock button of the SIM card and when accessing we will have to uncheck the option lock card of the smartphone. Before completing it instruct me the number for the last time. But, to make the process you must follow much clearer, we leave it here:

• We enter the Settings.
• We went down to Security.
• We choose SIM Card Lock.
• We deactivate the option and confirm it by entering it one last time.

There is also a secret code that should work on all mobiles, regardless of their brand, because it is one of those secret Android tricks that work on all terminals that are based on the Google operating system. To do this, we have to follow these steps:

• Open your phone app
• Open the app bookmark
• Enter the code: ** 04 * OLD PIN * NEW PIN * NEW PIN # and press the green call button.

If you leave the "new" space empty, no PIN code will be configured

In case you have tried to remove the PIN from your SIM card, you may have found that the method does not appear in the same way on your smartphone. This change occurs because each of the different layers of customization in the Android landscape, decides to change the method to be used and therefore not only changes the aesthetics, but the steps to follow are different. However, usually the steps are very similar, changing only the name of the menus or adding an extra step to the process.

So that you do not have to put the security number of the phone card ever again, we are going to show you how you can do it from your smartphone whatever brand it is.

Do it on Xiaomi phones

The first of the cases that we find is for the terminals that use MIUI, because the popular layer developed by the Chinese manufacturer widely changes the options on Android Stock that are the ones that we have shown you just on these lines. This method will be able to carry out in all versions of xiaomi's operating system, so it is present in Xiaomi, Redmi and Poco models.

What we will have to do in this case to get to the desired option is this:

• We start by accessing the Settings.
• Then we touch on Password and security.
• Followed by Privacy.
• Later we choose our phone number.
• We enter SIM lock settings, where we will be able to remove the applied security.

On Realme, OPPO and OnePlus mobiles

The process to remove the PIN on Realme, OPPO and even OnePlus mobiles is based on a series of common options given that the customization layers of all these brands have similar options. That is why we will have to do the following:

• Enter the Smartphone Settings.
• Then access Security.
• Next, tap on the SIM card lock.
• This will be where we can deactivate it completely.

On Samsung smartphones

In case we have a Samsung mobile, the process to remove the security of the id card is not too different from what was previously seen in Android. In this case, the method is effective for all terminals with One UI in any of its versions.

• We'll start by going into Settings.
• Followed by accessing the Biometric data and security options.
• Now we choose Other security settings.
• We choose to set up SIM lock > select the card.
• To finally deactivate this option and that it is not necessary to add our card PIN again. Although, before we must re-enter the key to let us disable this function.

How to do it on Huawei

With our mobile of the Chinese firm in hand, the process to ensure that the code is not requested again when we turn on the smartphone or when we introduce the SIM card is very simple in Huawei smartphones with any version of EMUI.

This consists of some steps that we explain in detail:

• Enter the Smartphone Settings.
• Then tap on Security.
• Then, slide to the section called More settings.
• Now we access the section called SIM lock settings.
• Finally, you just have to deactivate that you ask us for the key with the card or cards of our terminal.

And in the others?

For all other users who do not have a mobile of the brands mentioned, they will have to follow the same steps that we showed at the beginning for all Android models. Manufacturers such as Motorola or Nokia, are based on Android Stock to not modify the parameters, making the manufacturer has not changed the site or the process so that they stop asking us for this security that many do not need.

However, there are other phones with minority customization layers, such as Vivo or ZTE that should not change the location of the card's PIN too much. If you do not locate it, just open the always useful search engine of the Settings app and enter the text "SIM". This will show you all the settings of it.

On iPhones

In Apple devices the process to remove the security of the SIM is not too different from what is seen in the Android panorama, here we must also introduce it for the last time after following the next route. In addition, it will be much simpler, since all these phones share the same operating system, iOS, and without any layer of customization in between. Even, with the passage of the updates, the steps we must follow to get rid of the card key have not been affected:

• We access the Settings.
• We enter Mobile Data.
• Followed by SIM PIN.
• We deactivate the button.

The same code that we have shown you a few lines above to change or delete the Android code, works with Apple smartphones. Again you will have to access your phone app and, in the dialer, enter the code: ** 04 * OLD PIN * NEW PIN * NEW PIN # and press the green call button.

The Dangers of Removing your PIN

Many people do not choose to remove the PIN from the SIM card because it is a security mechanism that prevents using the mobile phone if it is turned off. It is a valid option, although since the patterns or unlocking systems are present it is no longer indispensable.

However, you should keep in mind that, in doing so, there are a number of others who are in trouble after making this change and, therefore, we must be sure of what may be putting themselves in danger to make the right decision.

Phone access for anyone

In case of loss or theft this security code will offer an extra protection, although, however, to bypass the SIM lock it is only necessary to remove the card from the device so that the person who has found the phone or has removed it can get rid of this key.

Therefore, we should not fear anything if we choose to remove the PIN from it, it will always be better to avoid it than to have problems every time we turn off the mobile, something highly recommended for older people or those who do not master technology. In addition, as you have seen, the steps to get rid of this four-digit password are simpler than they seemed at first.

Access to contacts

By removing the protection of that card we are leaving free access to anyone who finds it to know the contacts that we have been storing in the memory of the SIM itself. This will be the only data they will be able to know about us.

It is clear that it can be quite a risk if you dedicate yourself to calling everyone with our number and impersonating us. For this reason, to prevent them from trying to scam people or try to impersonate our identity, theirs is that the SIM PIN is maintained. And so we can get rid of greater evils.

You're more exposed to scams

Now that the phone number has become the most used double verification system, having access to the SIM and not needing security, someone could make purchases, subscribe to services and ultimately make our accounts tremble. Although, if we have not chosen to remove the PIN from the card, we will not have to worry about anything.

Therefore, if we remove the PIN, we must be very quick to call the operator and cancel the card before it is too late. Basically, so that no one can impersonate our identity and use the double verification system against us to empty our wallet.

One less layer of security

When we turn on the smartphone for the first time, we are asked for two codes. The first is that of the SIM, while the second is that of access to the phone. If we remove the first one, we are removing a layer of protection to the data mentioned above.

In addition, remember very well that you have removed it and do not try to enter the SIM PIN as the unlock code of the phone since what you can get without you even noticing, is to lock the smartphone by mistakenly entering the password or access code. Avoid future headaches and keep the security of your phone card intact.
