A mobile phone or mobile (also called cellphone and handphone) is an electronic device used for mobile telecommunications (mobile telephone, text messaging or data transmission) over a cellular network of specialized base stations known as cell sites. Mobile phones differ from cordless telephones, which only offer telephone service within limited range, e.g. within a home or an office, through a fixed line and a base station owned by the subscriber and also from satellite phones and radio telephones. As opposed to a radio telephone, a cell phone offers full duplex communication, automates calling to and paging from a public land mobile network (PLMN), and handoff (handover) during a phone call when the user moves from one cell (base station coverage area) to another. Most current cell phones connect to a cellular network consisting of switching points and base stations (cell sites) owned by a mobile network operator. In addition to the standard voice function, current mobile phones may support many additional services, and accessories, such as SMS for text messaging, email, packet switching for access to the Internet, gaming, Bluetooth, infrared, camera with video recorder and MMS for sending and receiving photos and video, MP3 player, radio and GPS.

The International Telecommunication Union estimated that mobile cellular subscriptions worldwide would reach approximately 4.6 billion by the end of 2009. Mobile phones have gained increased importance in the sector of Information and communication technologies for development in the 2000s and have effectively started to reach the bottom of the economic pyramid.

Does anyone know of plans for teenagers for cellular phones that are 30 or less per month?
Q. Just give me any plan that is under 30 and tell me how many minutes you recieve, and if nights and weekends are free and if it includes text! It's a great help! I'm just confused by the cellular world!

A. I highly recommend a pre-paid Trac-phone.It includes text.I average one 200 minute card a month for $39.95.I also bought a double your minutes card for $45.So,I'm getting 400 minutes each time I reload.I had no problem with loss of coverage on vacation from Atlanta,GA to Upstate New York.The phone was on discount at Wal-Mart for $14.95.Other phone cards average $10-30 for 60,and 120 minutes.Buy the highest you can get and the cost per minute goes down.It averages 10 cents a minute.

What is the cheepest cellular phone service for mutiplte phones?
Q. Cingular used to be good, but since they switched to Att it has been horriblely expensive. A phone bill should never be more than an eletric bill. But our last bill was over $300.00, before we never paid more than $60.00.

A. We use an ATT family plan, no texting or insurance but all the other extras like call waiting , forwarding, v-mail, nationwide roaming and unlimited long nationwide distance etc. We have a block of time per month, about 700 anytime minutes with roll over minutes. We always have a surplus at the end of the month and seem to be losing roll over minutes faster than we can use them. Bottom line we spend $110 total (with taxes etc) for 5 phones. And the price doesn't go up and down because we don't tolerate the over charges. Don't ever base your pricing on their advertised plan price without taking into consideration the taxes and fees.
