Popular Terms used on Mobile Commerce (M-Commerce)

SIM (Subscriber Identity Module)

There is a microchip inside the SIM card that stores information about the user. Phone book information can also be stored on the SIM card – phone numbers and their associated names. SIMs can be easily removed from phones and placed in other devices. Subscribers’ existing accounts and phone numbers will be used immediately on the new phone.

There are several pros to SIM cards, including their affordability, their secure connection, and their ease of use. They may be incompatible with some devices or may be difficult to use for some people.

R-UIM (Removable User Identity Module)

CDMA SIMs are similar to GSM SIMs, but they are designed for networks other than GSM. It is possible to interchange some R-UIMs between phones that support GSM and those that support non-GSM.


  • User data can be protected and increased through R-UIM.
  • Switching between devices is easy with this R-UIM.
  • User data changes can also be tracked with R-UIM.


  • The creation and maintenance of R-UIM can be expensive.
  • Setting it up and using it can be challenging.

3G (3rd-generation)

3G refers to third generation technology. The first generation of cellular phones were analog. A digital phone is considered a second generation (2G) phone. A 3G network is characterized by increased data speeds, always-on data access, and a greater capacity for voice calls. In comparison to older 2G and 1G networks, 3G technology provides three times the speed of data transfer.

The security of your data is assured with 3G. Compared to older networks, 3G is more reliable since it is a newer technology. While using your phone, you can save energy since 3G uses less power. A 3G network is able to reach farther away from your phone than a 2G or 1G network due to its increased range.

4G Fourth Generation

In terms of wireless mobile radio technologies, it is used to describe those that offer faster data rates than current 3G (third generation) technology. In addition to being more data-centric, 4G networks also rely on standard Internet technologies, including IP. VoIP is typically used to provide voice services. There are two main types of 4G technologies: WiMAX and LTE (Long Term Evolution).

Increased speeds and data capacity are possible with 4G. Compared to previous generations, the phone is smaller and more pocketable. In contrast to 3G and 2G technology, 4G offers a wider range of coverage and can be used in areas without 3G coverage.

Due to its less concealable design, the new design may not appeal to all people. It may take longer to get a 4G phone because it requires a newer model. With 4G, you can access areas where there is no 3G service currently available, and there is greater coverage than with 2G or 3G technology.

CDMA (Code-Division Multiple Access)

Wireless technology that uses digital signals is called CDMA. In many specific technologies, it is an implementation of a general type of technology. CDMA is also commonly used to refer to a family of technologies used by Verizon Wireless and Sprint in the US. T-Mobile and AT&T use GSM, which competes with this technology.

Unlike the original signal, the information in CDMA is spread over a much larger bandwidth than the original signal because it’s a spread spectrum. It is not possible for more than one user to share one base station (tower) with CDMA, unlike many competing technologies. CDMA allows more users to connect up to a point where the quality of the call would suffer beyond a predetermined threshold.

MMS (Multimedia Message Service)

Multi-media messaging service that combines text, sounds, images, and video between two or more networks. Standardized Protocols like WAP are used in MMS and require bearer services like GPRS or 3G to operate. With MMS, you need a dedicated channel, a multimedia messaging relay, a multimedia messaging server, and a multimedia messaging database, as opposed to SMS.

  • Benefits of MMS
  1. In the network, multimedia content can be created, sent, and received through MMS. The following are some benefits:
  2. Creating own content with text, pictures, audio, and video and transferring it between user’s terminals.
  3. Real-time sharing of multimedia messages between friends and colleagues. Suitable for demonstrating real-world tools and processes.

SMS (Short Message Service)

It is a wireless service that allows subscribers to send and receive alphanumeric messages via email or paging systems, as well as voicemail. Providing concise information is reliable and low cost. Multiple subscribers can receive the same message simultaneously. The SMS service has some limitations. The main limitations are as follows:

  • Data is transmitted only in text format.
  • In general, messages are limited to 160 characters.
  • In terms of WAP technology, SMS is not so suitable.

GPS (Global Positioning System)

In GPS signals, three different bits of information are carried: pseudorandom codes, ephemeris data, and almanac data. These bits of information constitute GPS signals. GPS is a satellite based navigation system, which is made up of a network of satellites placed into orbit by the US Department of Defense. The first pseudorandom code identifies the satellite. Almanac data are sent and received by the satellite, and ephemeris data contain information about the satellite’s status. Controlling aviation services is one of the major applications. This system can be used to access the Internet, forecast the weather, and use mobile technology.
