A mobile radiotelephone, often in an automobile, that uses a network of short-range transmitters located in overlapping cells throughout a region, with a central station making connections to regular telephone lines. Cell phone is also called as mobile telephone. Professional cell phone greetings are a simple, cost effective way to professionalize your image. First let’s look at what an unlocked cell phone. Some cell phones are designed to use a Subscriber Identification Module card or SIM card for short. A SIM card is a microchip that stores subscriber data. The SIM card is issued by a carrier and provides cell service by activating any phone into which it is inserted. A locked cell phone, however, will only recognize a SIM card from a particular carrier. If the cell phone is unlocked, it will recognize a SIM card from any carrier. The “lock” is software setting that keeps the cell phone “loyal” to one carrier.
The advancement in digital technology and microelectronics has included many applications like alarm clocks, calculators, Internet browsers, and voice memos for recording short verbal reminders, while at the same time making such telephones vulnerable to certain software viruses.

But commandments usually come in tens, so think of this as the first Ten Commandments of cell phone etiquette, with amendments to follow.
Telecommunications system in which a portable or mobile radio transmitter and receiver, or “telephone,” is linked via microwave radio frequencies to base transmitter and receiver stations that connect the user to a conventional telephone network. The geographic region served by a cellular system is subdivided into areas called cells. Each cell has a central base station and two sets of assigned transmission frequencies; one set is used by the base station and the other by mobile telephones. To prevent radio interference, each cell uses frequencies different from those used by its surrounding cells, but cells sufficiently distant from each other can use the same frequencies. When a mobile telephone leaves one cell and enters another, the telephone call is transferred from one base station and set of transmission frequencies to the next using a computerized switching system.
