Any starter pack, even received free of charge during the campaign, must contain an insert with special codes PIN, PIN2, PUK and PUK2, which you are invited to remember and not to disclose to anyone. However, far from every instruction you can find information about why such codes are needed and what opportunities they open up for the user.
Guard operator
Traditionally, when selling a SIM card, it is completed with an instruction or an insert on which the values \u200b\u200bof the four main codes are written: PIN, PIN2, PUK and PUK2. The main task that the operator set when inventing such sophisticated names is the protection of the subscriber.
The question is, why do you need as many as 4 codes for this, if you can limit yourself to just one? In fact, access to the SIM card is protected by only one code - PIN. It is what the phone requires when you turn it on. But suppose the code has been modified by the user and forgotten, which happens very often. As you know, after three incorrect attempts to enter, the PIN is blocked and it is no longer possible to enter it again, even if you finally remembered it. This is done on purpose - because for convenience, the PIN consists of only four digits, which, using a large number of attempts, it’s quite possible to pick up.
One can imagine what would happen in this case with the service centers of operators besieged by crowds of people who forgot their PIN. It is for this that the insert on which the PUK code is written serves. Its main function is to unlock the PIN code. The calculation is based on the fact that by entering the wrong PIN three times, the user (if he is the real owner of this SIM card) will find the treasured insert and will unlock the access using the PUK code. There is also a restriction on input attempts - a maximum of 10. If this number is exceeded, nothing will save the SIM card.
In addition, there is also a PIN2 code, it is responsible not so much for the security of the SIM card as for access to certain functions and additional services of the operator. For example, the call cost display function, or some types of call barring, can be protected with this code. However, given the fact that the scope of the code is rather narrow, only a very small percentage of subscribers use it. The PUK2 code, as you might have guessed, is used to unlock PIN2 if you entered the wrong code several times in a row. Do not be afraid if only two codes are present on the insert to the starter pack - PIN and PUK1. Some operators and SIM cards simply do not support PIN2 and PUK2, and to access the “secure” functions, a password is used that is entered directly from the telephone keypad.
Phone code
Apart from the PIN and PUK codes, there is the so-called “phone code”, the main task of which is to restrict access to some functions of the phone. Initially, the phone does not have a code (the user must install it), or a standard code is installed (for phones different manufacturers can be "0000" or "1234", which is indicated in the operating instructions). A limited number of attempts are also given for input, in case the limit is exceeded, the code is blocked, after which it is impossible to change the status of options that are protected by this code. So in the phones
Samsung and Motorola phone code can block access to SMS messages or pictures from the gallery. And in nokia phones You can configure the key lock so that the system asks for the phone code each time you try to remove it. Discover forgotten code the phone will not work, and calling the operator will not help either.
The only way out if the phone code is locked is a flashing (as an option, unlocking using a data cable, PC and special programs).
To summarize
PIN - This is a personal four-digit code designed to gain access to the SIM card and preventing its unauthorized use.
PUK code - This is a universal SIM card unlock code in the event of a three-time incorrect PIN entry.
PIN2 - This is a personal code that prevents unauthorized access to various phone features or operator services
PUK2 Is a universal PIN2 code unlock code.
Phone code - This is a password that restricts unauthorized access to phone features or personal user information.
Attention!
What to do if you forget your PIN:
1. Remember 4 digits is not so difficult, try to remember. If you did not change the code, then try entering the standard one.
2. Find the packaging from the starter pack. The insert shows the PUK code that unlocks the forgotten PIN.
3. If the PIN code is already blocked, and the packaging from the SIM card could not be found, contact the operator. In this case, it is desirable to provide a maximum of personal data: first name, last name, passport, phone number, approximate date of the last call and SMS, as well as which numbers were most often called.
The PIN is a personal identification number. Used not only in SIM cards, but also credit. The PIN code is the password for access to both the card and mobile phone. To disable the PIN code, you must enter the PUK code, which is located on the plastic card (holder) of the SIM card or additional documentation (box).
Accordingly, in order to unlock PIN1, you must enter PUK1, for PIN2 - PUK2. If the PUK code was entered incorrectly 10 times, then the SIM card is blocked forever. If you have lost documents from the SIM card, you must contact the nearest office cellular operator. Have a passport with you.
When unlocking it is often enough to enter only the PIN code. The SIM card is blocked if the code is entered incorrectly three times.
In order to disable the PIN code on Android, go to “Settings”, then “Security” or “Location and Security”, then “SIM card settings”. Opposite the item “Pin-code” there will be a tick. When removing it, you must enter the correct pin code. After that, the smartphone will turn on without a password.
Unlocking on Samsung smartphones is almost identical, but due to the use of branded shells, some points may differ. To unlock the pin code, go to "Settings", then the tab "My device", then "Lock screen", then "Lock screen". Here you can set both a pin code and a graphic key.
In order to disable the PIN-code, you must enter it in the "PIN-code".
On some Samsung smartphones, the pin code is located in the Security tab and is disabled in the same way.
To disable the PIN code on the Android tablet, go to "Settings", then "Security", then "SIM card" or "PIN code". You must uncheck the box next to the pin code and enter the password.
Another way
If you have forgotten your password, you can make a “HardReset”. For most Samsung models, you need to turn off the smartphone, hold down the power button and the Home button at the same time. After the company logo appeared, you need to find the item “Wipe Data Factory reset", Hereinafter" Delete All User ". Navigate through the items by volume buttons. Confirmation is done by the Power button.
After that, select the “Wipe Cache Partition” item and confirm. After all the actions, select the “Reboot” item. The smartphone will reboot.
This option has a minus - it removes all user data, as well as contacts that were in the phone’s memory.
For other models without the Home button, entering the same menu is done by simultaneously pressing the power and + or - buttons. After the logo appears, the buttons must be released. This option not suitable for iPhone.
There are two situations in which a pin code becomes necessary, the standard is two - a desire to block the TV and situations when it is already locked, but the user forgot his password. There are also cases when a person changes the factory code, setting his own, and forgets about it.
If the device is locked, you can find out about this by seeing instead of TV programs a blue screen with a key or a field for entering a password displayed on it. Also, wanting to include, for example, child lock, you can not do without knowing the pin code. Regardless of the circumstances, in this case there is no unsolvable problem.
To unlock the Samsung Smart TV, you need to have a remote control (RC). Without it, the issue cannot be resolved. The user needs to know a special combination of numbers. Sometimes, in extreme cases, you will have to return to the factory settings, reset the channel settings and tune them again. In the most difficult cases, the master flashes software on the Samsung TV again.
In most situations, owners can cope on their own, without the help of specialists. This is especially not difficult if the instructions from the TV are preserved.
SocialMart WidgetHow is the code issue resolved
The easiest way to find out the standard pin code for a Samsung TV is to get instructions from your model or find it on the Internet. It contains a special section devoted to this issue. There you can find out what to do if the password has been changed and after it is lost. Without instructions and access to the network, you can only count on your own memory, which, unfortunately, often fails in such matters, and a blocked device also blocks access to the Smart Hub.
Standard for Samsung Smart TVs, the manufacturer sets a simple pin - 0000 (less often 1111). If the owner did not change it or did not use it at all before, there will be no problems. If there were changes, as an option, you can reset the settings to return the old password.
The pin code for Samsung TVs is reset using the remote control in a simple way:
You need to turn on your TV;
Then, in a clear sequence, press the Mute button + Update button - Update button + Update button.
In order to have previous access in the hub and continue to use TV, you can restore the factory code (for TVs of assembly until 2012, this is the same 0000 by default). You need to find the EXIT button on the remote control, hold it down and hold for at least ten seconds.
For newer models, from 2012, the user password reset procedure is carried out by pressing the buttons from the remote control in the sequence: Mute, 8, 2, 4, Power (power button). You need to press the buttons quickly.
When it’s not always a password
Before you unlock a Samsung TV to watch TV programs with Smart technology, you need to find out the exact cause of the inconvenience by answering the question: "Do I really know why the problem appeared?"
The main nuances:
Without a remote control from a Smart TV, nothing can be restored. If it is defective or lost, you should start acquiring a new remote control;
If every time after turning off the Smart TV the channel settings are lost, it means that the matter is in the firmware and it needs to be updated;
You can check the operation of the remote control using an ordinary camera on the phone, holding any button from the remote control and sending it to the telephone camera, if there is a flash in the photo, then everything is in order with the remote control, and if the TV does not respond to it, you should call the wizard.
