| SIM SIM (Subscriber Identity Module) is a small card that contains a mobile network subscriber's account information. This allows the phone to use the card to attach to a mobile network. The SIM card is most commonly associated with GSM and UMTS mobile networks. Moving a SIM card from one phone to another allows a subscriber to switch mobile phones without having to contact their mobile network carrier. SIM cards can also be used by a phone to store limited amounts of data, such as phone numbers and text messages. | Dual Sim |
| Type A number of display technologies and types used in mobile phones TFT (Thin Film Transistor), IPS (In-Place Switching), OLED (Organic Light Emitting Diode), AMOLED (Active-Matrix Organic Light-Emitting Diode), Super AMOLED (an even advanced version of AMOLED), Resistive Touchscreen (Resistive touchscreens contain two-layer of conductive material with a very small gap between them which acts as a resistance), Capacitive Touchscreen (Capacitive touchscreen technology consists of a layer of glass coated with a transparent conductor) | QVGA |
| Size The industry-standard way of representing display sizes is publishing their length in inches. The screen-to-body ratio is a measure that relates to the size of the screen bezels. The bigger the ratio, the smaller the bezels are, meaning the display takes up a larger area on the device's front. | 2.4 inches |
| Resolution Display Resolution is the measuring way of how much pixels does a display contains. A higher resolution means more pixels and more pixels provide the ability to display more visual information (resulting in greater clarity and more detail). | 240 * 320px |
| OS Every Mobile Phone system runs on a base software called Operating System (OS). Operating System controls all basic operations of the Mobile (such as smartphones, PDAs, tablet computers, and other handheld devices). The Operating System allows the user to install and run third party applications (apps), apps are used to add new functionality to the device. | Feature Phone |
