Change SIM PIN Code? You have a new mobile phone contract or have been sent a new SIM card / eSIM? No matter whether you get a new number or keep your old number. With the SIM card you automatically get a new PIN.
How to change or even disable the SIM PIN, we explain for Android smartphones and tablets in the following:

Change SIM PIN or switch off SIM PIN?
The SIM PIN is the password and access to your smartphone with contract. Only by entering the SIM card PIN you can use and activate your mobile phone contract or prepaid card.
The PIN with the phone number used for years has been stored in your head. If you forget the SIM PIN of your mobile phone card or enter the SIM card PIN three times incorrectly, you must enter the PUK. If you enter the PUK incorrectly three times, your SIM card will be automatically blocked by the provider.
To unblock or unlock your mobile phone card or SIM card, you must call the respective mobile phone provider so that they can reactivate and unlock your SIM card. It is also possible that a new card will be sent to you.
How to change your PIN Code
You want to keep the SIM PIN you have used over the years and change the PIN for your new number accordingly? The procedure is similar for most Android smartphones.
To change the PIN, proceed as follows on an Android smartphone:
