SIM Card And All You Need To Know ?

A SIM card, also known as subscriber identity module or subscriber identification module (SIM), is an integrated circuit running a card operating system (COS) that is intended to securely store the international mobile subscriber identity (IMSI) number and its related key, which are used to identify and authenticate subscribers on mobile telephony devices (such as mobile phones and computers).

It is also possible to store contact information on many SIM cards. SIM cards are always used on GSM phones; for CDMA phones, they are needed only for LTE-capable handsets. SIM cards can also be used in satellite phones, smart watches, computers, or cameras.

A SIM card contains a unique serial number (ICCID), international mobile subscriber identity (IMSI) number, security authentication and ciphering information, temporary information related to the local network, a list of the services the user has access to, and two passwords: a personal identification number (PIN) for ordinary use, and a personal unblocking key (PUK) for PIN unlocking. In Europe, the serial SIM number (SSN) is also sometimes accompanied by an international article number (IAN) or a European article number (EAN) required when registering online for the subscription of a prepaid card.

SIM Card Pin Lock

A personal identification number (PIN), or sometimes redundantly a PIN number or PIN code, is a numeric (sometimes alpha-numeric) passcode used in the process of authenticating a user accessing a system.

The PIN has been the key to facilitating the private data exchange between different data-processing centers in computer networks for financial institutions, governments, and enterprises.

PINs may be used to authenticate banking systems with cardholders, governments with citizens, enterprises with employees, and computers with users, among other uses.

In common usage, PINs are used in ATM or POS transactions, secure access control (e.g. computer access, door access, car access), internet transactions, or to log into a restricted website.

SIM Card Puk Code Unlock

A personal unblocking key (PUK), sometimes called personal unblocking code (PUC), is used in SIM cards to reset a personal identification number (PIN) that has been lost or forgotten.

Most mobile phones offer the feature of PIN protection. After switching on the phone, if the PIN security function is active, the user is required to enter a 4-8 digit PIN to unlock the SIM card and connect to the mobile network.

Without this, functions such as phone calls (except for emergency calls), text messages and mobile data will not be available. If the wrong PIN is entered more than three times, the SIM card will become locked.

It can be unlocked by entering the PUK code provided by the mobile service provider, which may be available on the SIM card’s packaging, the contract, or provided by customer service after identity verification.

After the PUK code is entered, the PIN must be reset. If the wrong PUK is entered ten times in a row, the SIM card will become permanently blocked and unrecoverable, requiring a replacement.

Mobile phone users are therefore advised by most providers to keep their PUK written down in a safe place separate from the device.

How To Unblock And Unlock Your SIM Card ?

If your phone uses an Airtel, 9mobile, Glo or MTN SIM card to operate, you can activate a security feature called a SIM PIN.

The SIM PIN protects your SIM card from unauthorized use, and must be entered in order to use your phone.

Enter it incorrectly three times and your SIM card becomes locked. You can unlock your SIM card on your own, however, by typing in a PIN unlock key. Your carrier can provide you with the unique PUK code for your device.

Step 1

Contact your wireless carrier by calling the toll-free customer service number. (Find this on your provider’s website or a recent invoice.) You will need to verify your account password before the PUK code is released to you.

Step 2

Power your phone on. You will see a “SIM Locked” or “Enter PUK” message. Type in the eight-digit PUK code and press “OK.”

Step 3

Type in a new four- to eight-digit PIN code when prompted, then press “OK.”

Step 4

Verify your new PIN code by re-entering it when prompted. Press “OK.” Your SIM is now unlocked.
