A SIM card (full form: Subscriber Identity Module or Subscriber Identification Module) is an integrated circuit (IC) 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). Technically the actual physical card is known as a universal integrated circuit card (UICC); this smart card is usually made of PVC with embedded contacts and semiconductors, with the SIM as its primary component. In practise the term "SIM card" refers to the entire unit and not simply the IC.
A SIM 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. It is also possible to store contact information on many SIM cards.
SIM cards store network-specific information used to authenticate and identify subscribers on the network. The most important of these are the ICCID, IMSI, authentication key (Ki), local area identity (LAI) and operator-specific emergency number. The SIM also stores other carrier-specific data such as the SMSC (Short Message service center) number, service provider name (SPN), service dialling numbers (SDN), advice-of-charge parameters and value-added service (VAS) applications. (Refer to GSM 11.11.)
SIM cards can come in various data capacities, from 8 KB to at least 256 KB. All can store a maximum of 250 contacts on the SIM, but while the 32 KB has room for 33 mobile network codes (MNCs) or network identifiers, the 64 KB version has room for 80 MNCs. This is used by network operators to store data on preferred networks, mostly used when the SIM is not in its home network but is roaming. The network operator that issued the SIM card can use this to have a phone connect to a preferred network that is more economic for the provider instead of having to pay the network operator that the phone discovered first. This does not mean that a phone containing this SIM card can connect to a maximum of only 33 or 80 networks, instead it means that the SIM card issuer can specify only up to that number of preferred networks. If a SIM is outside these preferred networks, it uses the first or best available network.
Each SIM is internationally identified by its integrated circuit card identifier (ICCID). ICCID is the identifier of the actual SIM card itself: i.e. an identifier for the SIM chip. Nowadays ICCID numbers are also used to identify eSIM profiles, and not only physical SIM cards. ICCIDs are stored in the SIM cards and are also engraved or printed on the SIM card body during a process called personalisation. The ICCID is defined by the ITU-T recommendation E.118 as the primary account number. Its layout is based on ISO/IEC 7812. According to E.118, the number can be up to 19 digits long, including a single check digit calculated using the Luhn algorithm. However, the GSM Phase 1 defined the ICCID length as an opaque data field, 10 octets (20 digits) in length, whose structure is specific to a mobile network operator.
The SIM stores network state information, which is received from the location area identity (LAI). Operator networks are divided into location areas, each having a unique LAI number. When the device changes locations, it stores the new LAI to the SIM and sends it back to the operator network with its new location. If the device is power cycled, it takes data off the SIM, and searches for the prior LAI.
Most SIM cards store a number of SMS messages and phone book contacts. It stores the contacts in simple "name and number" pairs. Entries that contain multiple phone numbers and additional phone numbers are usually not stored on the SIM card. When a user tries to copy such entries to a SIM, the handset's software breaks them into multiple entries, discarding information that is not a phone number. The number of contacts and messages stored depends on the SIM; early models stored as few as five messages and 20 contacts, while modern SIM cards can usually store over 250 contacts.
Hey! My name is Molly and I'm having trouble with the online community. It won't except my serial number from my game and when I type it in and hit the register button it pops up with a "Invalid serial code" thingy. I was wondering what that was all about. Plus i couldn't have been wrong since I tryed it multiple times.
Thats great and all, but I purchased the game and played it, it works great. But when I go to the sims site to access the exchange I log on under the same email and passwork to orign, it then brings me to the game registration page. If I try to fill it out the site tell me the serial number is incorrect, which is impossible. I have tried opening a seperate Sims account, along with trying all of my expansions serial numbers and tried in several brozer, restarting my computer, opening a closing the Sims, and swearing. Nothing works.
Have you ever looked at a price tag and wondered why on earth there are so many numbers and letters on it? What are they all for? One of those numbers sets is usually the SKU number (stock keeping unit). SKU numbers are unique to each store and allow the store to keep track of each item in inventory. SKU numbers can be anything you want to be but are most often about 8 alpha-numeric digits.
SKU numbers are important for every store to use because they make life way easier. Each SKU is recorded within your internal tracking system (which is hopefully an inventory management system and not a manual spreadsheet). Once within your system, SKUs will make it possible for you to record loss easily, make smarter inventory decisions, track the exact location of each item, increase the accuracy of your inventory and warehouse activities, and for your employees to easily look up inventory to help your customers. When done right, a SKU number can even tell an employee what item should be attached to your SKU.
The store I worked for in college did this with no hiccups. In fact, the only reason I ever realized that they reused SKUs after a number of years is because one customer decided to return an item she bought 12 years previous and had never worn. The item still had the tags and the old SKU number, which corresponded with a new item when I typed it into our system.
