You can no longer make calls with your smartphone because you have forgotten the PIN code of your SIM card? Do not panic ! An emergency code linked to your line allows you to unblock it: you just need to know where to find it.
You probably unlock your smartphone many times a day using your fingerprint, facial recognition, a pattern or even a PIN code that you know by heart from typing it. This small security formality allows you to access all the content of the mobile. However, and more occasionally, you may also be required to enter a second PIN code, the one linked to your telephone line. The situation arises, for example, when you restart the device or after turning it off and on again. And this four-digit code has nothing to do with the one you defined to secure access to the phone’s content: it is associated with the SIM or eSIM card provided by your telephone operator and allows you to connect to its network to phone.
When using the SIM card for the first time, you must use the generic PIN code provided by the operator (often 0000, 1111 or 1234) and modify it immediately to define a more personal combination. It is possible to deactivate the entry of this code when turning on the phone, but it is not recommended. Because if the smartphone is lost or stolen, anyone can use it to make calls, use up your entire data plan or even call premium rate numbers, thereby draining your bill. And since this code is rarely used, it’s easy to mistype it on the screen or simply forget it. However, after three unsuccessful attempts, the smartphone freezes. It is therefore impossible to use it to make calls! This is where a special backup code comes into play: the PUK code.
The PUK code for Personal Unblocking/Unlocking Key (personal identification number unlocking key), is none other than your only lifeline if your memory ever fails you when entering the PIN code on your smartphone. It generally consists of eight digits (sometimes less) and was provided to you by your operator along with your SIM or eSIM card. Exclusively linked to your SIM card, it cannot be modified.
To find it, there are two solutions. The first is to get your hands on your telephone subscription contract. The PUK code normally appears on this document but also on the plastic support in which the SIM card was inserted. It is therefore strongly recommended that you keep these documents in a safe place that you will remember.
If you can’t get your hands on these documents, don’t panic. There is still one way to find out your PUK code. To do this, you can connect to your customer area on the operator’s website (Orange or Sosh, Free, Bouygues, SFR or RED) from another mobile or a computer connected to the Internet. You will need the username and password associated with your account. The Help or Support section should allow you to retrieve your PUK code. You can also contact your operator’s customer service or try your luck at one of its points of sale (by providing identification).
When you finally have your PUK code, all you have to do is enter it in the appropriate field displayed on the smartphone after three incorrect PIN code entries. You will then need to set a new PIN code (don’t forget it!). Please note, you have 10 attempts for the PUK code. After these tests, if the code is not valid, the line will be permanently blocked.
