    How to unlock the SIM

    Before illustrating yourself in detail how to unlock the SIM inserted in the smartphone (or tablet with support for the cellular network), it seems only right to provide you with some preliminary information in this regard.

    To begin with, keep in mind that to perform the operation covered by this tutorial you must be in possession of the pin code of the card. In case you don't know, the PIN (acronym for “Personal Identification Number”) is a code consisting of four digits, which is automatically and randomly associated with each SIM produced, but which can be modified by the user if necessary.

    If you have not changed it, the PIN to use is the one you find in the sales package of the SIM, on the relevant one plastic holder. If covered by a silver patina, in order to visualize it you must first remove it (perhaps with the help of a coin).

    The PIN must be entered after turning on the phone for use services connected to the cellular network, such as phone calls, SMS and Internet connectivity under the 3G / 4G / 5G network. If not inserted when requested, it is still possible to use the smartphone, but not the functions related to the card in the strict sense. This therefore means that in the event of a blocked SIM you will not be able to make and receive calls, you will not be able to send and receive SMS and you will not be able to surf the net using the data connection of your telephone operator.

    When the PIN code is entered for three times in a row incorrectly, the SIM yes block and to fix it you need to type the PUK code (acronym for "Personal Unblocking Key"). Unlike the PIN, it is a code consisting of eight digits and which is only used to unlock the card in situations like the one just described. It is provided directly by the telephone operator of your interest and cannot be changed at will by the user.

You have not been able to trace the PIN associated with the SIM and therefore you have no way to unlock the card? Well, maybe I can still help you and explain how to unlock your phone SIM under these circumstances.

Some telephone operators, then, allow to obtain the data in question also by connecting to thepersonal online area of its website or by accessing the appropriate one mobile app or, again, by contactingassistance.

    To submit the replacement request, you must go to a shop of your mobile phone provider and communicate to the employee what your intentions are. The operation typically is paid and has an average cost of 10 euros. Before going to the store, you can still ask for more information about the customer service of your telephone operator, by contacting the latter as I explained to you in my tutorial on the subject.
