When they give us a new SIM card, it will always be accompanied by two very important codes. The first of them is the PIN code, a code that we have to enter every time we change the card to another terminal, or every time we turn it off and on. The second, the PUK code, is one that you may never have used before, since it mainly serves as a “lifeline” in case you enter the PIN code wrong too many times. But, Did you know that there are two more codes?
These two additional codes that we tell you about are somewhat more “hidden”, and they are so for a simple reason: its use is much more specific than those we already know. Some operators offer these PIN2 and PUK2 codes when they send us our new SIM card, although this is not always the case. In this article we are going to tell you more about these two codes, pointing out the differences between the versions we know and these.
So are the PIN2 and PUK2 codes
We start with the PIN2 code, which is the one that allows more functionalities of the two. This code has 4 to 8 digits, and is used to enable or disable certain features on our phone. The main use of this code is usually enable or disable what is known as fixed dialing. This feature allows you to restrict calls so that the user can only call certain phones, being an ideal measure for parental control. In addition, thanks to it we can also interact with other services such as speed dial or the consumption data counter.
Contrary to what happens with the normal PIN code, which is only entered once, this PIN2 will be requested each time we are going to interact with these functions that we tell you about. This code is already included with the rest with the SIM card, and like the normal PIN code, it can also be changed for another one that we want. Another point in common with the normal PIN code is that if we enter it wrongly three times we will also block the SIMand that is precisely where the PUK2 code comes in.
The PUK2 code it is, in essence, identical to the one we know. Is about an 8-digit code in all cases which is used to unlock our SIM card in case it has been blocked. The difference is that while PUK is used when we wrongly enter the PIN code, PUK2 does the same but with PIN2. If this happens to us, by entering the PUK2 code we can establish a new PIN2 code for our SIM card. Of course, be careful with this code, because if you enter it wrongly 3 times (the number may vary depending on the operator) you will block your card forever. This, moreover, It can not be changed.
Request these codes from your operator
As we have said before, all SIM cards have PIN2 and PUK2 codes, regardless of the operator to which they belong. However, as the use of these is more limited, some of them do not inform their clients of these codes directly, but, even so, all clients have access to obtain it in a very simple way. Some, such as Vodafone, allow us to consult these codes in their section for customers, but others such as Yoigo do not offer this possibility.
If you want to get these PIN2 and PUK2 numbers, we recommend that you first try it through these customer services that the operators have, looking for the phone number in them and within it, the code option. If you can’t find it there, you can always go to one of the official channels available to your operator. These, just by supplying them your personal data, telephone and the ICC code of the SIM cardthey will give you your codes without much problem.
