How GSM Technology Operates
Global System for Mobile Communications, abbreviated as GSM, is a standard developed to describe protocols for second generation (2G) digital cellular networks. GSM technology uses time-division multiple access (TDMA) which allows multiple users to share the same frequency channel by dividing the signal into several time slots. This operation enables efficient use of the spectrum, which is a valuable resource.
GSM technology primarily includes multiple components:
- Mobile Station (MS): The handheld device used by consumers that includes the SIM card.
- Base Station Subsystem (BSS): This part consists of base stations and the controllers responsible for handling calls and managing communications.
- Network and Switching Subsystem (NSS): This subsystem routes calls, maintains call sessions, and enables roaming.
A GSM SIM card stores user data such as phone numbers, texts, and authentication details. The card's primary role in communication involves establishing the user’s identity, enabling secure access to the mobile network. Each card contains a unique Integrated Circuit Card Identifier (ICCID) that serves as a serial number, differentiating it from other cards in the system.
Functionality of Dual SIM Cards
Dual SIM cards offer distinct advantages over single SIM alternatives. They allow users to utilize two different phone numbers from different carriers without needing two devices. This is particularly beneficial for individuals in business or those traveling frequently. Here’s how they function:
- Seamless Switching: Users can easily switch between SIM cards directly from their device settings without physically switching out cards.
- Separate Billing: Cost management becomes easier when personal and business costs appear on separate bills. Users can choose how they want to route calls based on price or quality.
- Network Optimization: With two SIMs, users can select the stronger network signal between two available carriers at any given point, enhancing connectivity and reducing costs further.
In addition to connectivity, dual SIM functionality caters to various applications:
- Users can take advantage of carrier-specific plans.
