Let me introduce you to this new mobile phone tracking software that can be installed on your 3G cell phone. This software integrates 2 kinds of system: the programming system and the GSM systems. The programming system relates your sim card to your phone IMEI/serial number. The GSM system sends a text message to another cell phone number and also to your email whenever the original sim card on your cell phone is changed. This in short means that your cell phone can only be used by your sim card. The details of the sim card that has been input including its cell phone number are in the text message and email that has been sent. You can call up the person and instill fear in them and inform them that all you want is your cell phone back.

Do you really want to be available for anyone and everyone on a 24/7 basis?  What do I mean?  A famous person once said that the more available you make yourself; the more available everyone will expect you to be. People will actually be annoyed if you are not instantly and constantly available rather than being pleased when you do call. People expecting you to be available all the time may be annoying.  Cell phone calls follow you everywhere you are including your bathroom.  Even during nighttime when you want to rest, cell phones continue to ring and annoy you.  If it is important, no problem but if it is very menial, why you need to be bothered so late.Today in this modern society, we live in and the proliferation of cell phones we see people talking anywhere and everywhere.  If used for business, this may prove to be very effective and worthy.  However, for very menial issues being bothered in your sleep and even during your bathroom time may be quite annoying if not outright disgusting.  However, if you make yourself available all the time, you created your own nightmare.Cell phone etiquette is getting to be a forgotten concept.  You will see people talking on the phone loudly and disturbs people nearby in restaurants and even in offices.  I am sure by now, once or twice in a meeting you will notice that when a cell phone rings, almost everyone around will immediately look for their cell phones.  If you were the one talking, and then the person in front of you talks on his phone, how would you feel?  I am sure you will feel belittled and ignored.  Rude practice, and should be changed.It may help people who use cell phones to follow certain degree of etiquette with respect to the use of cell phones specially in places where you may seem rude if you use or even when your cell phone rings.When you are in a place of worship, it may be necessary to leave your cell phone in the house or at least turn it off if you do not want to be away with it.  This is because ringing cell phone will not just disturb you while you pray it will also disturb others.  You do not need to show off your expensive gadget in a place of worship.  During meetings, please turn off your cell phone; it is rude to have your phone ringing while somebody speaks.  Disruption may cause problems especially when the meeting tackles extremely important issues.  However, if you are waiting for terribly important call, you may use the vibrate mode of your cell phone to alert you when a call is in-coming and leave the meeting if you need to answer the call.  You may also inform the possible caller that you are in a meeting and that you cannot be disturbed.When traveling and if you are on-board an aircraft, you will be required to turn off your phone.  This is because electronics devices may interfere with the aircraft’s avionics.  Thus, it is a requirement to turn of your phone for safety reasons.  However, for extremely long flights, airline companies allow cell phone usage at a certain time, if you really need to make a phone call, use this time allotted if necessary.Cell phone have become to be a necessity nowadays, that is why most people use it and cell phone manufacturers have continuously develop different usage and functions for this very small gadget.

In recent years, cell phone usage has sky rocketed. Consumer reviews and tech columnists have devoted volumes to the subject of which phone to choose. The loyal followers of the iPhone, the Blackberry, the Palm, the Sidekick, ect, have engaged in fiery online debates over which one is better.
Relatively little has been written, however, on comparing cell phone carriers. To a considerable extent, a cell phone is only as good as the carrier that provides the signal. We’ll see here that evaluating carriers and their monthly plans is every bit as involved as reviewing the cell phones they run on.
J.D.Power and Associates have reported that the quality of *all* cell phone services has become so consistently high across the board that there was no longer a reason to even own a “land line” anymore. Paradoxically, ask any of your friends about cell phone reception horror stories and they’ll have plenty of fireside tales to tell you. J.D. Power and Associates also asserts that call carrier customers who did not have their complaints resolved by customer service were six times more likely to switch carriers. And in fact, this happens all the time. If one isn’t satisfied with one’s cell phone, it’s easy enough to get another one. But dropping a cell phone carrier is another matter. The advent of phone carrier contracts with cancellation penalty fees has largely come about to combat cell phone carrier dissatisfaction. Even the advent of 3G Networks, which was announced with great fanfare, still has not quelled a considerable percentage of cell phone customers that are not happy with their carriers. According to comScore Networks, one in four cell phone customers are not satisfied with their wireless carrier. With such an astonishingly large statistic, it’s clear that cell phone signal technology is still in its adolescence. Keeping this in mind, let’s now compare carriers.
According to comScore, Verizon Wireless has consistently been rated the best carrier in terms of coverage and customer service. Overall, only six percent of customers break their service contract.
AT&T/Cingular come in second, just behind Verizon. Alltel’s customer service contract breakers are more numerous, coming in at 9 percent, while Sprint/Nextel have an even higher dissatisfaction rating at 11 percent. At the bottom of the heap is T-Mobile, with 15% of customers wanting to break out of contract obligations.
But there might be more to this than meets the eye. The above comScore survey is not location specific and uses the percentage of customers breaking the service contract as the litmus test for popularity. A J.D. Power and Associates survey does indeed confirm Verizon as the leader, but mentions that this is particularly true in the Northeast, where Verizon’s coverage is the strongest. T-Mobile, with the lowest rating in the comScore survey, actually ranked first in the Southwest, according to J.D. Power. Moreover, Verizon also ranks lower in terms of the phones that run its service, which tend to use CDMA technology rather than GSM. As a result, Verizon phones tend to not accept SIM cards (Subscriber Identity Modules) which prevents their use when travelling overseas. Verizon’s rates also ranked considerably higher than its rivals, and though its customer service gets high marks, its bills tend to be confusing to read.
J.D. Powers also claims that Sprint has a strong popularity in the Southwest, yet at the same time it concedes that Sprint also ranks lowest in call quality. The latter statistic was also confirmed by a PC Magazine survey. By contrast, PC Magazine ranks T-Mobile as the best carrier in terms of pricing, and second only to Alltel in service plan options. T-Mobile also offers its service on a wide variety of phones and smartphones with GSM/SIM card compatibility enabling international use.
Prepaid cell phones deserve their own category all together. Virgin Mobile won the highest marks, just ahead of TracFone and T-Mobile respectively. Verizon, ATT&T, follow in order of decreasing popularity, with poor Sprint/ Nextel once again at the bottom of the heap.
Oftentimes people let their choice of service providers be determined by what phone they choose. Let me suggest that you might just as easily consider the reverse route; find the best carrier for your needs and chose your phone from there.

There’s a lot of buzz on whether cell phones emit enough radiation to cause ill health effects. This concern arises because the cell phone is placed close to the head during use. Hence it puts the radiation in direct contact with the tissue in the head.

Cell phones have low-power transmitters in them. Most car phones have a transmitter power of 3 watts. A handheld cell phone operates on about 0.75 to 1 watt of power. The position of a transmitter inside a phone varies depending on the manufacturer, but it is usually in close proximity to the phone’s antenna. The radio waves that send the encoded signal are made up of electromagnetic radiation.

Electromagnetic radiation is made up of waves of electric and magnetic energy moving at the speed of light, according to the Federal Communications Commission (FCC). When talking on a cell phone, most users place the phone against the head. In this position, there is a possibility that some of the electromagnetic radiation will be absorbed by human tissue.

All cell phones emit some amount of electromagnetic radiation i.e. cell phone radiation. Given the close proximity of the phone to the head, it is possible for the cell phone radiation to cause some type of harm to the 118 million cell phone users in the United States. What is being debated is how much cell phone radiation is considered unsafe and if there are any potential long-term effects of cell-phone radiation exposure.

The FDA states that “the available scientific evidence does not demonstrate any adverse health effects associated with the use of mobile phones.” However, that doesn’t mean that the potential for harm from electromagnetic radiation doesn’t exist. Cell phone radiation can damage human tissue if it is exposed to high levels of radiation, according to the FCC. RF radiation has the ability to heat human tissue, much like the way microwave ovens heat food. Damage to tissue can be caused by exposure to RF radiation because the body is not equipped to dissipate excessive amounts of heat. The eyes are particularly vulnerable due to the lack of blood flow in that area.

The added concern with non-ionizing radiation (the type of radiation associated with cell phones) is that it could have long-term effects. Although it may not immediately cause damage to tissue, scientists are still unsure about whether prolonged exposure could create problems. This is a sensitive issue because of the millions of people using cell phones today. In 1994, there were 16 million cell phone users in the United States alone. As of July 17, 2001, there were more than 118 million.

Here are a few health problems that may be linked to cell phone radiation:
• Cancer
• Brain tumors
• Alzheimer’s
• Parkinson’s
• Fatigue
• Headaches

If you are worried about the potential risks of cell-phone radiation, here are few ways to reduce your risk:
• Use a hands-free headset
• Use a phone that places the antenna as far away from you as possible
• Limit calls inside buildings
• Use a health protector such as Chi Waveguard. Available for only $19.95. It neutralizes the negative effects of electromagnetic fields radiated from cell phones or electrical products.

With all the various models offered by cell phone service providers, it can be confusing when deciding which cell phone to buy. And of course, cell phone technology continues to improve rapidly, bringing even more features to the newest cell phones on the market. But here are a few guidelines regarding what you can expect to get when you buy a cell phone.

First of all, remember that the cell phone is not the most important part of this communication equation, the network is. So choose your cell phone service provider first, based on the quality of performance and customer service as well as other usability factors.

Once you have your cell phone provider in mind, it’s a good idea to visit their store to physically inspect the phones that they have available. This is important because you can’t tell very much about how usable a cell phone is simply by a picture. Usually, it’s necessary to actually hold them and see how easy they are to use in order to determine how well a particular phone will meet your needs.

Generally speaking, you’ll find that most cell phones are broken down into three categories, basic phones, advanced phones, and smart phones.

The basic phone these days is capable of both making voice calls and text messages. This kind of phone is probably the best choice for most consumers, as they are the most inexpensive phones that you can buy and are relatively easy to use. They may not have some of the fancy capabilities that you’ll find in the more advanced phones, such as photos, video, and Bluetooth capability for wireless headsets, but for basic cell phone usage they are hard to beat.

The more advanced phones these days offer extras like being able to shoot photos and videos and send them to others over the cell phone network, or store them on built-in memory cards. They may also include music players and options for storing music files. And another very popular feature on more advanced cellular phones is Bluetooth capability allowing for use of a wireless headset. Of course all these extra features come at a price, usually up to two to three times the cost of a basic cell phone.

The most advanced cell phones on the market these days are called smart phones and are kind of a combination between an advanced cell phone and a PDA, or personal digital assistant. The main advantage to these kind of cell phones is that they eliminate having to have two pieces of electronic equipment to carry with you at all times by combining them both into one unit. Of course, these models can not only perform all the functions of an advanced phone, but they can also allow you to schedule appointments, keep track of addresses, and even access e-mail. These are by far the most expensive cell phones though, commonly costing several hundred dollars.

As you can see, there is a wide variety of cell phone models to choose from. But before you buy, be sure that you know exactly what features will be most important to you in daily usage, and then buy the cell phone that best meets those needs.

Gone are the days when phones were used only for voice communication. Advancement in cell phone technology now allows you to send text messages, take pictures, set reminders for daily chores and pay your bills. With the wide range of features available, choosing the right cell phone can become quite mind-boggling.

Currently, Nokia, Motorola and Samsung are the market share leaders for the global cell phone market, and offer a wide selection of cell phones to meet every person’s needs. Cell phone costs range from less than $100 to more than $400, depending on the specifications. Your choice of cell phone should be dictated by the features you would like your cell phone to have. The first thing to consider is the cell phone size. As your cell phone will be carried with you most of the time, a slim and lightweight cell phone is the best choice. Cell phones also come with or without flip covers, and nowadays all cell phones allow text-messaging services.

Cell phones come with varying storage capacity for contacts – from as low as 50 to more than 200. If you want to use your cell phone to take pictures, then in-built camera phones of more than one mega pixel should be considered. Multimedia phones also offer short-duration video and voice recording features. These phones also have slots to attach to external devices for additional storage of your favorite pictures, music and videos. Another important thing to consider is the cell phone battery life. Battery life is the hours of talk time the battery supports. Many cell phones normally come with 250 minutes of talk time.

Other cell phone accessories include hands-free or speakerphone features. These would allow you to make or answer calls even while both hands are occupied, especially while driving. Cell phones with bluetooth or infrared technology allow the phone to connect wirelessly to your PC without having to invest in an expensive data cable. WAP enabled cell phones allow you to check emails even when you are on the move. It also enables you to use your phone as a modem. Medium-range phones come with in-built radio and MP3 features. Some phones also provide the option of changing cases to match your clothes to the occasion.

Cell phone ringtones have become popular nowadays and are a great way to add style to your phone. All phones come with preset ringtones but some phones come with options that allow you to compose ringtones. Many websites provide ringtone download services for free or at nominal charges.

A mobile phone or cell phone is an electronic telecommunications piece of equipment. The majority of current cell phones connect to the network using a wireless radio wave transmission technology, although satellite phones are exceptions. These cell phones communicate by means of a cellular network of base stations, which are known as cell sites, which is in turn linked to the conventional telephone network and were first introduced in the early to mid 1980s, the so called 1G generation.

Earlier cell phones operating without a cellular network, the so-called 0G generation, such as Mobile Telephone Service, date back to 1946. In anticipation of the mid to late 1980s, most cell phones were sufficiently big that they were time and again permanently installed in vehicles as car phones. In the midst of the advance of miniaturization, at this time the vast majority of cell phones are handheld.

Features of a cell phone
In addition to the usual voice function of a telephone, a cell phone can hold up many additional services such as SMS for text messaging, packet switching for access to the Internet, and MMS for transferring and receiving photos and video. A number of the world’s largest cell phone manufacturers consist of
• Alcatel
• Audiovox
• Fujitsu
• Kyocera
• LG
• Motorola
• NEC
• Nokia,
• Panasonic (Matsushita Electric)
and a lot more…..

There are in addition specialist communications systems related to, but separate from cell phones, such as Professional Mobile Radio. Mobile phones are also distinct from cordless telephones, which in general operate only within a limited range of a specific base station. Technically, the term cell phone includes such devices as satellite phones and pre-cellular mobile phones such as those operating via MTS that do not have a cellular network, while the related term cell(ular) phone does not. In actual fact, the two terms are used almost interchangeably, with the favored term varying by location.

Technology on which cell phone works
Cell phones and the network they function under vary a lot from provider to provider, and even from nation to nation. On the other hand, all of them communicate through electromagnetic radio waves with a cell site or base station, the antennas of which are by and large mounted on a tower, pole, or building. The cell phones have a low power transceiver so as to transmit voice and data to the nearby cell sites, usually 5 to 8 miles away.

When the cellular phone or data device is turned on, it registers with the mobile telephone exchange, or switch, with its only one of its kind identifiers, and will then be alerted by the mobile switch as soon as there is an incoming telephone call. The handset continuously listens for the strongest signal being received from the neighboring base stations. As the user moves in the region of the network, the mobile device will hand off to new cell sites.

Cell sites have comparatively low power (habitually only one or two Watts) radio transmitters, which broadcast their being there and relay communications involving the mobile handsets and the switch. The switch in turn connects the call to a different subscriber of the same wireless service provider or to the public telephone network, which includes the networks of other wireless carriers. The conversation between the handset and the cell site is a stream of digital data that includes digitized audio (except for the first generation analog networks).

The technology or the know-how that achieves this depends on the system that the cell phone operator has adopted. A number of technologies include AMPS for analog, and TDMA, CDMA, GSM, GPRS, EV-DO, and UMTS for digital communications.
