Long Form of Sim Card 

Subscriber Identity Module

SIM Full Form is a Subscriber Identity Module. SIM is basically a smart card found inside cell phones. SIM carries a unique number specific to the owner and stores data and prevents its usage when removed from the phone. Nevertheless, unlike the CDMA or Code Division Multiple Access phones, only Global System for Mobile or GSM type of phones use SIM cards.

The SIM card comprises a chip that is inserted into the phone to initiate usage by tapping into a particular network. The most important feature of the SIM card, which makes it work, is the authentication key.  

The authentication key of a SIM card is given by the service provider. This has to be activated whenever a new SIM card is used. It is a huge blessing that allows individuals to change phones without changing the SIM card.

SIM Full Form – Additional Information

We all know that when we buy a mobile phone then to activate it we need a SIM card. Very few are actually aware of what the full form of SIM is or its importance.  It is a smart card or an integrated circuit card (chip) that is used in GSM phones (Global System of Mobile communication) and besides encrypting data (SMS) and voice transmission, it stores user identity data that authenticates and identifies the subscriber on the telephone network circuit.

  • SIM card, as it is popularly known, can store user settings pertaining to the storage of phone numbers, data messages, etc. It is identified by a unique code that is engraved on the chip known as ICCID or Integrated Circuit Card Identifier as well as IMSI or International Mobile Subscriber Identity. SIM is engraved on removal and portable smart card that we know as the SIM card. This has the portability of being used in different mobiles and yet retaining its unique identity.

  • The first-ever SIM card was developed in Munich in 1991 by Giesecke & Devrient and the initial 300 cards were sold to a Finnish wireless network operator. Besides the ICCID and IMSI codes, the SIM has temporary data about the local network and the services that the user has permission to access. It also has a provision of storing two passwords – a PIN or personal identification number for regular use and PUK or personal unblocking code for unlocking the PIN.

What is the importance of SIM

  • The SIM cards are available in two variants – mini-SIM cards and micro-SIM cards. The first type is used in normal GSM mobiles and the micro-SIM card is inserted to activate a smartphone. A SIM card can be changed from one handset to another and yet the data stored on it like your contacts, their numbers and data messages, etc remain intact. This is the major advantage of a SIM card because it gives them the security of communication.
  • In case the mobile handset gets damaged or the battery runs low, then by just replacing the card from damaged mobile to another puts you back on track of mobile communication. In the current world, there are too many crimes and cases of terrorism. 
  • The threats are usually carried out using a mobile phone since you can make the call and destroy the card. However, since each number is associated with a particular SIM card, it is easy to trace the owner of the number and thus reach the culprit.
  • When a person applies to obtain a SIM card, that person’s residential proof and photo identity are collected for verification. Only after satisfactory verification of the user, the network provider opens the service for that number. 
  • This ensures that there is no misuse of the SIM. However, the clever criminal minds find loopholes in the system and collect many SIM cards for nefarious use. Nonetheless, since SIM is unique in its character, there is nothing much that can be done in terms of cheating and finally, the card gets detected on the network.

Various features of the SIM card

  1. This is a modern age when everything can be obtained in multiple numbers. Similarly, as far as SIM card usage is concerned per person, there is no need to have just one. Presently, many GSM, as well as smartphones, have a facility of inserting two SIM cards and are known as “dual-SIM phones”. This is particularly practical for businessmen etc who can then take the privilege of keeping the two identities separate. 
  2. One SIM card can be used to store personal numbers and messages; whereas the other card can be exclusive for business purposes. This gives a scope for privacy and organization of contacts as per personal and business grouping.
  3. These dual SIM cards can be operated in two ways. In some phones, the cards need to be switched to use and the other type of phones especially smartphones have the facility to keep both the SIMs active at the same time. Even though currently the mini and micro SIM cards are widely used, there is a third type that is the size of a credit card. But it is not in use anymore. 
  4. The micro-SIM was designed with compatibility in mind. The same phone should have the facility of mini as well as micro card and thus the contact area of reading the card data is kept the same. In some cases, instead of buying a separate micro SIM, people cut their mini cards with a Knife or scissors to the micro size.

SIM and network providers

The SIM card opened a whole avenue of business for different network service providers. The providers need not possess or run a cellular telecom network. It is a leased capacity from the actual network owner and these are just mobile virtual network operators (MVNO) who provide a SIM with their network to the customer.

In today’s age, there is a competition between service providers and though initially, it was not possible, now it is possible to change your service provider with the same telephone number that has been assigned to you. This is called “number portability”. So in case you are not satisfied with the transmission, connectivity, or services of your network service provider, you can opt for a better carrier.

Even though in India it is not prevalent as far as the use of GSM phones are concerned, but in some countries like USA, UK, Canada, Australia, etc there is a system of the mobile phone being locked to a particular service provider and the SIM card is not accepted of any other carrier. However, some providers do give the option of unlocking the phone and then the customer has the liberty to use whichever SIM card he likes.

How a SIM works

  • A unique code IMSI (International Mobile Subscriber Identity) identifies the SIM card on the carrier’s networks. Each SIM card is tied to its location and if the phone is carried to a different state, then it goes on a roaming network, where the base service provider has tie-up with other networks with good transmission signals in the area. Since these are external leased lines, the charges for calls made on the roaming network are always more. Each SIM has a personalized authentication key known as K¡ provided by the operator. The same key is also stored in the database of the operator’s network. This database is known as the Authentication Center or AUC.

  • When the mobile handset is started, it gets the IMSI from the SIM card. This is then passed on to the carrier to request the right of entry and authentication on the network. Then through a series of processes, the operator matches the K¡ with the database number and if the two numbers match, the customer is granted access to the operator’s network. Talking on a mobile phone may seem like an easy task. Nonetheless, the whole process of getting a connection for communication through a small chip called the SIM card is surely a complicated mission.

Full-Form of GSM Sim: Singapore Institute of Management

  • Full-Form of SIM refers to the Singapore Institute of Management. Also known by its abbreviated form SIM, It is the largest institute in Singapore in respect of private education and professional training. The institute, or let us just simply refer to it as SIM, was established in the year 1964 by the Singapore Economic Development Board.
  • Also known as EDB, the Singapore Economic Development Board is a statutory body that creates a framework to ensure the development of business and investment avenues in the country. The SIM is located in Clementi, Singapore. Under the aegis of the SIM, Singapore’s first privately funded institute the SIM university was established in the year 2005.
  • The Ministry of Education has approved a number of degree courses that the SIM University provides. Because of the extensive course structure and national status, the university is popular and has an enrollment of about 10.000 students admitted in different disciplines. In the year 2008, the SIM had initiated the process to make UniSIM programs more accessible to adult learners. Permanent residents who enroll in the UniSIM’s programs are eligible for a government subsidy of 20% of tuition fees and eligible Singaporeans get 40% subsidy.

  • The SIM offers degree courses in a variety of disciplines and conducts about 50 educational programs in different countries like the United States, the United Kingdom, Europe, and Australia. Apart from full-time courses, the SIM also offers part-time courses and diplomas. The SIM offers undergraduate degrees like Bachelor of Communication, Bachelor of Arts Economics, Bachelor of Science in Marketing, and the Bachelor of Science in Economics.

  • As far as master courses are concerned, the university offers such degrees on Science in Digital Marketing, Science in Engineering Business, etc. Most of these degrees are awarded by foreign universities like the Bachelor of Communication is awarded by RMIT University, the Bachelor of Arts Economics is awarded by the University of Buffalo, the Master of Science in Digital Marketing is awarded by the University of Southampton, etc.

  • The SIM has four campuses and this fact makes it Singapore’s most extensive privately funded institute. The SIM headquarters is the center for all student activities and events. There is a SIM Management House that undertakes membership and workshop activities. The administrative functions are conducted in the SIM Clementi Centre. The SIM provides SIM Global Education @Ulu Pandan, which is one of the largest facilities that provide boarding facilities, seminar hall, etc.

Full-Form of SIM: Security Information Management

  • SIM Full Form stands for Security Information Management. SIM refers to a terminology often used in the Information Security field. The term is used to allude to a collection of data, which includes log files. The collected data is moved into a central repository that undertakes a thorough trend analysis. Thus, it does what the name sounds: it manages the data collected and performs security analysis.
  • Products with Security Information Management, or let us just refer to it as SIM, behave like software agents that operate on computer systems, which need to be analyzed. These agents then transfer the log information to a server that functions as a centralized system or “security console”. 
  • This “security console” is an important system, to begin with: it generally displays reports, charts, graphs, etc of the information it has received. In fact, there are some software agents that make use of local filters with the purpose of lowering down and manipulation of data that they eventually transfer to the “security console”. The “security console” is handled by a human being, who is tasked with the duty of reviewing the information by undertaking analysis and report alerts, if any.
  • A security console is necessary because it performs the primary task of correlation and analysis and the information sent to the console is normalized by the software agents into a commonly used form, which is generally XML (Extensible Markup Language). Often the use of terminology SIM is mistaken to mean a reference to the feature of protection of one’s infrastructure from any potential security breach. It is to be understood that SIM refers to a mechanism that unearths the irregular behavior of the computer system with the help of techniques pertaining to data collection.
  • Thus, it would be wrong to understand the functioning of the SIM to be similar to that of Information Security Management (InfoSec), which is a terminology used in reference to the complete security mechanism that protects the computer environment. Apart from being referred to as SIM, Security Information Management is often referred to as log management, which is totally different from Security Event Management (SEM). SIM is, however, a part of Security Information and Event Management (SIEM).

SIM Full Form: Society for Information Management

Full-Form of SIM refers to the Society for Information Management. SIM is one of the most prominent and preferred professional organization in the world, with 4,500 senior information technology (IT) executives, Chief Information Officers, academicians, and other IT think tanks. The organization endeavors to help in enhancing intellectual capital by bringing together IT intellectuals.
Let us explore some historical facts concerning the inception and developments surrounding the SIM. At the Association for Computing Machinery (ACM) conference held in Las Vegas in August 1968, the establishment of SIM was conceptualized.

This happened when a conversation was initiated between Robert Head with the Software Resource Group and Herb Schwartz with the United States Atomic Energy Commission. They discussed how inappropriate and insufficient emphasis on the management aspects of computing. This discussion went on to become the foundational principle of the SIM that came into being in the year 1982. Many stages of discussions and decision-making led to SIM.

A committee was instituted in the year 1968 that held its first meeting at the United States Atomic Energy Commission in the same year. Joseph P. Cunningham, Richard E. Dooley, Dr. James C. Emory, Robert B. Forest, W. Robert Widener, Robert K. Wilmouth, Robert V. Head, Dr. Alan J. Rowe, James G. Rude, M.H. Schwartz, and Robert G. Stevens were the founders of the society.

The meeting was followed by a conference “Bridging the Gap between the Management Function and Information Technology” held at the University of Minnesota in the year 1969. The conference was attended by more than 250 persons. The SIM has founded many programs for the purpose of furthering its founding goals and objectives. Some of those programs are as follows:

  • Advanced Practices Council: Also known by its abbreviated form APC, it is a platform of discussion where experienced IT executives come together and decide to discuss on various research-related aspects of IT. The council was established by Warren McFarten in the year 1991. Mr. Warren McFarten comes from the Harvard Business School.
  • Future Potential Program in IT: It is yet another endeavor of the SIM to provide progressive insights into the IT sectors and managerial aspects of the same. It was created with the purpose of promoting IT as a progressive career option among college students. This program was created in partnership with Microsoft, which later stopped funding the program since the year 2007.
  • Leadership Development Roundtable: LDR is modeled on the popular Regional Leadership Forum (RLF) and it addresses issues pertaining to leadership and development of personality.
  • SIMposium: It is a conference that invites discussion upon issues relating to IT sectors, controversies, new developments, amendments, etc. Till 2002, the conference was called SIM Interchange Annual Conference.

Full-Form of SIM: Space Interferometry Mission

  • SIM Full Form stands for Space Interferometry Mission. Also known as the SIM or SIM Lite or SIM Planet Quest, refers to a space telescope that was created by the United States National Aeronautics and Space Administration (NASA) in partnership with the contractor Northrop Grumman. The telescope was created with the purpose of finding small-sized planets that revolve in the possibly habitable areas of stars other than the Sun. 
  • The telescope could not come into official use as it was canceled in the year 2010. Before its cancellation, the telescope was intended to be launched in the year 2005, incorporated in the Evolved Expendable Launch Vehicle (EELV) but due to insufficient budget, the launch date was postponed many times.
  • The Purpose of the telescope was not limited to the search of small-sized planets in the habitable areas near stars but it could have helped in the mapping of the mysterious Milky Way Galaxy. It could have performed other tasks like a collection of data from stellar masses of stars, determination of the spatial aspects of dark matter in galaxies, and in gravitational microlensing effect that helps in calculating the mass of the stars. To achieve all these goals, the SIM would have used optical interferometry. Optical Interferometry is a scientific technique that gathers light with the use of many mirrors combined in an interference pattern.
  • The technology used in the SIM is advanced, as it can lead to the development of powerful telescopes capable of capturing images extrasolar planets. This technology can be used to ascertain whether those extrasolar planets have the capacity to sustain life forms. 
  • The SIM used another advanced technology and that was termed as “rulers”. Rulers have the ability to calculate in increments precisely. These rulers were designed to work as networks and they had shock absorbers in them to reduce vibrations during measurements.

SIM Full Form: Serving In Mission

Full-Form of SIM stands for Serving In Mission. It is a non-profit Christian mission organization. SIM is an international, interdenominational organization that was established in the year 1893. The founders of the SIM were Walter Gowans and Rowland Bingham, both from Canada, and Thomas Kent from the USA. Originally, the SIM was known by the name Soudan Interior Mission, with Soudan being a reference to Sudan of West Africa.

The organization, for many years, underwent changes & few mergers, and eventually, it settled for the abbreviated form “SIM”. In French-speaking nations, the organization is often referred to as Société Internationale Missionnaire. 

The headquarter of the SIM is located in Fort Mill, South Carolina, with many sending officers located in different parts of the world like France, South Africa, South Korea, Belgium, Singapore, Italy, New Zealand, the United States, Switzerland, and Australia.

The organization is an amalgamation of many distinct organizations, whose own histories date back hundred years ago.

Those organizations include Africa Evangelical Fellowship, International Christian Fellowship, Andes Evangelical Mission, and Sudan Interior Mission. Thus, the SIM is one of the most prominent and recognized Christian missionary organizations.

Let us explore some historical facts behind the establishment of the SIM. It all started in Sudan. The founders, Water Gowans, Rowland Bingham, and Thomas Kent, wanted to evangelize the Sudanese region. 

The first base of the mission was founded in the year 1902 and eventually its reach expanded to other regions of the country and then of the world. By the year 1998, the SIM had covered areas like Guinea, Niger, Nigeria, Senegal, Kenya, Liberia, Malawi, South Africa, Sudan, and Togo, etc.

In 1989, the SIM had merged with International Christian Fellowship, and with this merger, the SIM extended its reach to south Asian regions like Bangladesh, China, Nepal, India, Philippines, Mongolia, Pakistan, etc. In the year 1998, the SIM merged with Africa Evangelical Fellowship (AEF).

The purpose of the mission is to evangelize and attend to the needs of people; educate Christians to respect the values of Church, and to train churches and other Christian missions. As far as records of the year 2008 are concerned, the SIM has about 1800 missionaries actively engaged in about 37 countries, primarily in the regions belonging to South America, Africa, and Asia.

Full-Form of SIM: School for Improvisational Music

SIM Full Form refers to the School for Improvisational Music. SIM is a part of the Center for Improvisational Music (CIM) established with the purpose of educating students in creative music. The SIM sincerely engages in training aspiring students about music and since 2001, it has conducted about 20 interactive workshops, which have been attended by more than 800 students. 

The sessions conducted by the SIM include masterclasses, coaching, private tutoring, etc. The SIM brings together some of the most talented and renowned improvisers from the fields relating to contemporary music and jazz. The SIM provides sufficient opportunities for aspiring students to learn about creating music.
