When we change operators on the iPhone and receive a new SIM card, it is time to perform one of the most important tasks: change or remove sim pin on iphone.
It is convenient to do it as soon as you change the SIM card to avoid forgetting it and regretting it later, at least while these physical SIMs are still valid in the operators (the iPhone 14 has already started the path to end them).
Remove or change SIM PIN on iPhone
I have often come across iPhone users who changed carriers a long time ago and, when replacing the SIM, they kept the default PIN. They put in the one for the new card and forgot about it. Some time later, which usually coincides with an update that restarts the terminal (because turning off the iPhone is not in their vocabulary), they must enter the new PIN and do not remember it.
It is because of that it is convenient to change the PIN of the SIM card sooner. On iPhone, just follow these steps:
- We open Settings and go to Mobile data:
- Click on SIM PIN:


Here iOS 16 will ask us for the old PIN, which comes with the new card from the operator. We introduce it and then we must put the one we want:

May be the one we’ve always had or another that we remember more easily. With this, the iPhone PIN will be changed (different from the unlock code or password).
How to disable iPhone SIM PIN
If what we want is completely remove the PIN so you don’t have to enter it every time we restart the iPhone, we will follow a similar process. Of course, we recommend that you first change the PIN to one that is easy to remember before deactivating it. To do this, we will do the following:
- Go to Settings> Mobile data> SIM PIN as you can see in the screenshots above
- We deactivate the ‘SIM PIN’ option.
For security reasons, we will have to enter the PIN before deactivating it. In this way, no one who has taken our iPhone without permission will be able to deactivate this barrier that could allow anyone to use our mobile calling and data plan.
Something important to know is that you only have three attempts to enter the PIN correctly. If you fail those three attempts, you will have to resort to the PUK code, a ten-digit number that comes to you on the cardboard card from the operator and where the physical SIM card was inserted.
Don’t know where you have that cardboard card or don’t remember where you kept it? Don’t worry: you can contact the operator so they can tell you by phone. For this to happen, they will ask you to confirm your identity through some information, to maintain a certain level of security in the process.
iPhone with eSIM: new now, everyday in the future
In the future, this process should change in favor of eSIMs. A good part of the most modern iPhones already have it integrated, and now the ball is on the roof of the governments and regulators so that ending the cardboard SIM is a fact within a few years.
The operators in Spain already offer this service as a complement, and in some cases it even implies paying a little more than the monthly fee. Our colleagues at Xataka Móvil have a list with all the eSIM offers from the Spanish operators.
