Different Mobile Phone Components

A mobile phone is made up of different components systematically arranged according to the type and design. Any handset, whether it is an ordinary feature phone or a smart phone, has some important components besides battery as discussed below.

SIM card Slot
Any handset requires a small microchip known as SIM card for its operation. For inserting simcard, a slot is provided in every mobile phone. Some CDMA cell do not need SIM card but they apply some similar card known as R-UIM. The SIM cards are generally removable and can be placed in other hand handset. Some mobile sets come with fixed SIM cards which are not removable.

Battery
A mobile phone requires battery to work. Rechargeable battery is commonly used in all handsets. It is recharged by connecting to external battery charger which in turn is connected to a power point at any place. recargas telcel

Memory card
Located inside the handset, a memory card or chip stores the information on the phone. It stores all data like phone numbers, names and data regarding calls made, received, and missed calls, messages received and sent and many other data that we may want to store.

Display screen
Generally located on top surface of a cell phone, it displays all information that we search for on the screen in text and video forms. If we make a call it displays the number dialed or if we are sending message, it is displayed on the screen. Similarly, when we receive a call the phone number of the caller and name if any is displayed on the screen and when message received the message is displayed. When the mobile battery is discharged completely, the phone gets switched off and one cannot view the display unless the phone is charged again

Key pad
Key pad contains text letters, numbers, symbols and special characters. Phone numbers and text are entered with the help of these keys. Traditional keypads having 3-4 characters on single key are now largely replaced by QWERTY keypads. These days, with the popularity of touch screen phones, you can find mobile phones without key pads too.

Touch Screen
Some improved versions of mobile phone sets provide touch screen in place of key pad. Just by touching the screen, you can enter the menu and select different options to input any data or use any mobile function.
