A mobile phone, also known as cell phone, mobile phone or cell, sometimes shortened to just cell, phone or hand phone and sometimes referred to as mobile phone plans, is a mobile telephone that makes and receives calls over a short-range radio communication system while the user is traveling within a single phone service area. In many cases, the signal can be compromised by other wireless devices in the area and the call can be interrupted or lost. However, many modern cell phones are equipped with caller identification, or CID, which is similar to the security codes that are used in home phone systems. This feature provides users with the option of verifying that they are calling from a cell phone owned by the user and allows them to enter the code to let the other party know that they are on the call and not a personal mobile device.
Generally, most modern mobiles work using GSM technology, which is short for Global System for Mobile Communications. This type of system links together different mobile stations throughout the world, so that when one’s signal is weak or busy, it doesn’t mean that their phone is also out of service. There are many different mobile phone networks and providers to choose from, including AT&T, T-Mobile, Verizon, and Sprint. The service plan and pricing varies by network, as well as the features included in the plan.
Some newer cell phones, like the iPhone and Blackberry, include cellular data capability built-in. If the user chooses to have mobile data included as part of their monthly plan, they can use the iPhone’s built-in cellular data platform to send and receive unlimited amounts of mobile data while on the go. Users can use these applications to stay in touch, check email, search the web, play games, and connect with family and friends wherever they are. These applications make using a cell phone more fun and less of a hassle.
