Quick definition: ICCID stands for Integrated Circuit Card Identification Number. It's a unique 18-22 digit code that includes a SIM card's country, home network, and identification number. You'll usually find an ICCID printed on the back of a SIM card, but sometimes it's included in the packaging materials instead.
The ICCID is a globally unique serial number—a one-of-a-kind signature that identifies the SIM card itself.
The International Mobile Subscriber Identity (ICCID) is a twelve-digit number on your SIM card that determines which cellular networks your device may use. If you're developing cellular IoT gadgets, understanding what an ICCID is and how it works is crucial.
No, IMEI is not the same things as a sim card but it is tied to the device. Each device has a SIM and an IMEI. The SIM is associated with the network, whereas the IMEI is associated with the device. The SIM is identified by the Integrated Circuit Card Identification (ICCID) number.
An IMEI universally accepted code - dial the *#06# virtually on any phone.
Unfortunately, the IMEI number of a device cannot be used to directly find the SIM number. The IMEI (International Mobile Equipment Identity) number is a unique identifier for a mobile device, while the SIM (Subscriber Identity Module) number is a unique identifier for a subscriber on a mobile network.
Every SIM number is unique. It's usually 13 digits long and ends with a letter. You can choose to ignore this letter when asked to enter your SIM number. You'll find your SIM card number on the packet it came in, or on the actual SIM card itself, on the opposite side of the chip.
The PUK (Personal Unblocking Key) code is a code consisting of 8 digits. It is used to unblock your SIM card when you entered 3 times a wrong PIN code. A card blocked by the PUK code cannot be unblocked; it cannot be used any further and you have to replace it.
If your SIM Card # begins with 89014 then you have a GSMA-compatible SIM Card. Red Pocket GSMA utilizes a GSM Network and SIM Cards can only be activated once. If your SIM Card # begins with 89012 then you have a GSMT-compatible SIM Card. If your SIM Card # begins with 89148 then you have a CDMA-compatible SIM Card.
If you forgot or don't know your SIM PIN
Contact the carrier that gave you the SIM card. If you aren't sure which carrier to call, remove your iPhone SIM card or iPad SIM card and check the card for the carrier's name or logo. Ask your carrier to help you unlock your SIM card using the default SIM PIN or PUK code.
For Android Phones:
Open the Mobile Settings App. Click on Network and Internet and Tap on Cellular Networks. From available networks you can know the SIM card company.
Default SIM Pin Codes of Popular Mobile Carriers
Usually, a SIM comes with a default PIN code directly from your mobile carrier. These codes vary company by company.
The digits contain information on your mobile network and your account. Also known as a SIM serial number, this number is for the purpose of international identification. It will typically have nineteen digits and contains details about the carrier, your location, and when the SIM card was manufactured.
There's a unanimous code for all operators to check SIM card registration. Dial *16001#, then a pop-up will appear on the screen. Enter the last 4 digits of the NID. Press enter and next you'll receive a message containing the list of phone numbers that are registered under the NID.
Data that SIM cards contain include user identity, location and phone number, network authorization data, personal security keys, contact lists and stored text messages. SIM cards allow a mobile user to use this data and the features that come with them.
The SIM Registration Act (SRA) is a new law that requires all SIM owners to register their SIM so they can use their SIMs for mobile internet, call and text. All SIMs, including those in card and electronic form used for mobile phones, prepaid WiFi kits or other devices, need to be registered.
Once the SIM card is inserted, turn on your phone. You should see a message indicating that your SIM card is not activated. Dial the activation number provided by your service provider. This number can usually be found on the SIM card package or on the provider's website.
To activate your SIM card online, simply go to your carrier's website. Chances are, the support page you'll need to visit will be listed on the card. Once you've done that, simply follow the steps listed. Usually, you'll have to enter the phone number or SIM card number.
This is called a SIM PIN (personal identification number). Typically the user would use the GUI of the phone to enable the PIN. Some manufacturers have a default PIN value set with new SIM cards. Numbers such as 0000, 1234, or the last four digit of the cell phone number (MSISDN) are common.
Your PUK (Personal Unlocking Key) is an 8-digit code unique to your SIM card. If you don't know your SIM PIN, you can use your PUK code to unlock your mobile and reset your SIM PIN.
