Guidance on Cellular Phone Rental

Cell phones are selling like beer at a baseball game. As of August 2005, there were more than two billion cellular phone users around the world. This number is expected to keep growing and growing, setting one record after another. While cell phones may be old hat in industrialized countries, the astonishing fact is that even deep in the inland agricultural regions of developing countries you can see field workers with cellular phones. This is a revolution. Just as the internet is joining every country, the cell phone revolution links people from the hectic streets of New York and Tokyo to the tranquil islands of the Caribbean and the heartland of Brazil.

And it isn't just the cellular phone companies alone in this success. Cellular phone rental outfits are also capitalizing on this awesome little gadget that has changed the communications landscape radically. Cellular phone giants like Nokia, Seimens, Motorola, and Samsung may be reaping huge rewards from this technology, but cellular phone rental firms are also earning big chunks of money. The cellular phone rental companies could wll hit the big time with consumers who prefer to use this technology everyday but are still conscious of the price they have to pay on every call. Since international roaming charges can cost you big money, cellular phone rental can be the best option whenever you need cheaper phone rates, while not exhausting your own cellphone plan. This can be especially important during out of town and international trips.

Here is some basic guidance you should consider when renting a cellular phone:

1. Like car rental, cellular phone rental can be very convenient, but it does require a reasonable amount of money or a sufficient credit line.

2. Cellular phone rental company rates depend on the service offered, the cellular phone rental duration, and the type of the phone. Insurance can also contribute to the cost of the rented phone.

3. If you want to rent a cellular phone, you need to present valid ID and a major credit card or what can amount to a substantial deposit.

4. Rented cellular phones, which will usually be the latest models (meaning a longer battery life), normally come with a charger, a printed copy of how to use the cellphone, a protective pouch, and a SIM card. Extras offered by some cellular phone rental companies can include an extra battery, cigarette lighter charger, and data or fax modems for specific cellphone units.

5. Be aware that the SIM card may be unblocked and therefore open for intonal calls, which can mean a major phone bill. Some SIM also be open for international roaming. Ask before renting cellular phones. Afterwards is too late.

6. Some cellular phone rental companies add a premium every time the costumer makes calls and/or sends an SMS message. Check on this before closing the deal. You must know exactly what you are going to be paying for - and how much - to make a cell phone rental manageable.

7. Some cellular phone rental companies do "hot billing" which means that as soon as you return the rented mobile phone, you would instantly receive the bill. Note, though that some companies may reserve the right to adjust the final billing. A "hot billing" may not be the full amount. Always verify the cell phome rental companies billing rules.

8. There are cellular phone companies that offer prepaid SIM cards. All you do is to buy prepaid cards to use the rented phone. This can be very convenient if you want to keep one number every time you rent a phone, but not all companies will offer prepaid SIM cards.

9. Some cellular phone rental company offer family package that allow two phone rentals at the same time.

10. If you know you are going to rent a cellular, it may be a good idea to reseve one well in advance. This is particular true during peak periods such as holidays, when rental cellular phones are in heavy demand.

Cellular phone rental is well on the way to becoming an essential traveler's commodity, much like the rental car. However, it may not last. As the world-wide cellular network matures and becomes ever more tightly integrated with an increasingly high speed world-wide internet, competition should increase, prices should fall and new modes of cellular communication using VoIP (Voice over Internet Protocol) may make the present market structure obsolete. But for now, you can still do your budget a favor by carefully selecting and using a rental cellular phone when it's appropiate.

Richard has been following the growth and improvement of cellular phone technology and service since the early 90s. With cellular articles and resouces [http://altaglobal.org] is all about cellular phones.

Cellular Phone Repair

Cell phones have become a necessity for many people throughout the world. In such a scenario, life seems to come at a halt if there is a fault in your cellular phone and you need a repair.

Until recently, only the manufacturers undertook the cellular phone repair job. Opportunities now exist for entrepreneurial individuals to start their own lucrative business, either as an employee of a cellular phone repair shop, or having their own stand-alone cellular phone repair operation.

Some basic steps may be followed if your cell phone is not working properly. First, determine if the problem is with the phone or the battery by replacing the battery. If you can't hear callers, make sure the volume is turned up, the ringer turned on, or the battery is charged. If these strategies don't work, take your cell phone to a cellular phone repair center.

Nowadays, customers may bring in a faulty phone to any of the cellular phone repair centers. A Work Order Form will be issued, and a deposit towards the cellular phone repair service must be made. An agreement is then signed for receiving a courtesy phone. All cellular phones have a one-year manufacturer's warranty. The cellular phone repair centers will repair or replace phones under warranty as long as the user did not cause any physical damage to the phone. If the warranty has expired, the cellular phone repair center might charge for repairs. Once the cellular phone repair job is over and the phone is returned by the relevant cellular phone repair center, the customer returns the courtesy phone, makes the final payment and receives the repaired unit. Sometimes it's best to just purchase a new phone, because cellular phone repair costs can be as high as the cost of a new phone.

A cellular phone repair technician has several sophisticated tools and techniques available for the repair job, such as:

Cleaners - They are used in cellular phone repair since they are oxide dissolving contact cleaners. These equipments are used to clean dirty pins in the phone and thus aid in cellular phone repair.

Lamps - They are used while doing a cellular phone repair job to protect your eyes when you work. Table lamps come with high-frequency 4200Hz lamp without frequent sparking to avoid harmful effect to eyes, since a lot of work under deficient light at normal 50Hz/60Hz can cause short eyesight and many eye diseases. It is a very useful tool for people who are doing the cellular phone repair business.

Phone Open Tools - A cellular phone repair job requires opening up of cellular phones. Several tools such as screwdrivers made of magnetic alloy steel can be used for this part of the job.

Programmers - Cellular phone repair requires the cellular phone to be unlocked. Not all mobile phones can be unlocked with simple cable. Programming tools can be the only way to repair "death phones", those that have stopped working. A 24xxx chip reader can read and write EEPROM (Electrically Erasable Programmable Read Only Memory) in a phone without any problem. Power obtained from USB connection to computer port, serial port is used for reading/writing data during a cellular phone repair job. Programming tools are used in almost every cellular phone repair center.

Ultrasonic Cleaner - It is a device that transfers ultrasonic sound waves to a cleaning liquid or solvent that dislodges embedded dirt on objects immersed in it. The ultrasonic cleaner is used during cellular phone repair to clear the PCB board of cellular phones.

If your phone becomes faulty, don't panic. Just take the basic steps that have been highlighted above. If this does not work out, you can still take your phone to a cellular phone repair center where a cellular phone repair technician can solve your problem.

Wireless Without the Wires: Bluetooth Cellular Phone

They may call it a wireless phone, but standard cellular phones still require wires at some point. Besides the clunky charger, you also have to fumble with cords to use a headset and to transfer data between your phone and other gadgets. But there is an answer for anyone looking to cut the cord almost completely. With a Bluetooth cellular phone, you can chat on a wireless headset, transfer data magically through the air to a handheld, or connect with a Bluetooth-enabled car. But take care, as each Bluetooth cellular phone is not created in the same manner. While some carriers let you use a Bluetooth cellular phone for almost any means, others restrict it to a headset only.

Bluetooth is a standard developed by a group of electronics manufacturers that allows any sort of electronic equipment -- from computers and Bluetooth cellular phones to keyboards and headphones -- to make its own connections, without wires, cables or any direct action from a user. A Bluetooth cellular phone works at two levels:

It provides agreement at the physical level -- Bluetooth is a radio-frequency standard.

It also provides agreement at the next level up, where Bluetooth cellular phones have to agree on when bits are sent, how many will be sent at a time and how the parties in a conversation can be sure that the message received is the same as the message sent.

While it may sound complicated, a Bluetooth cellular phone works in a simple manner. A Bluetooth cellular phone communicates with different devices by sending data via a secure, low-cost short-range radio frequency. Using the technology, a Bluetooth cellular phone can connect to headsets, PCs can connect to printers or keyboards, and handhelds can connect to each other without any wires. Up to seven connections can be made at one time, at a speed of 1Mbps. All that's needed for any Bluetooth cellular phone to connect to another Bluetooth-enabled device is for them to be paired--normally, a hassle-free "handshaking" process for establishing a connection that takes seconds and can be found in most wireless connectivity menus.

What's in a Name?

In case you were wondering, what's "Bluetooth" in the term "Bluetooth cellular phone", Bluetooth gets its name from a 10th-century Danish king, Harald Blatand (or Bluetooth) who unified Denmark, Norway, and Sweden. According to legend, he had an affinity for teeth-staining blueberries.

Bluetooth Frequency

A Bluetooth cellular phone communicates on a frequency of 2.45 gigahertz, which has been set aside by international agreement for the use of industrial, scientific and medical devices (ISM).

A number of devices that you may already use take advantage of this same radio-frequency band. Baby monitors, garage-door openers and the newest generation of cordless phones all make use of frequencies in the ISM band. Making sure that a Bluetooth cellular phone and these other devices don't interfere with one another has been a crucial part of the design process.

Pairing up

Before you start talking on a Bluetooth cellular phone, you do need to know a few facts. A Bluetooth cellular phone has a range of 30 feet (10 meters), and the devices in question must use compatible versions of Bluetooth. The majority of Bluetooth cellular phones currently in the marketplace works on Bluetooth 1.1. (Two previous versions, 1.0 and 1.0B, were plagued with compatibility issues and have since been discontinued.) The Bluetooth Special Interest Group (SIG), a trade association and development group, is releasing newer versions that promise several upgrades and backward compatibility. Bluetooth 1.2, includes the addition of an anonymity mode, which masks the hardware address of the device to protect from identity snooping and tracking, and adaptive frequency hopping, which cuts interference by avoiding crowded frequencies. Bluetooth 2.0 has some enhancements; among them are narrowband channels, which will enable messages to be broadcast to a high number of devices without the pairing process, andhigher connection speeds of up to 12Mbps.

When no other means of connecting to the Internet is available, mobile workers can use their Blue tooth cellular phone as a modem. An advantage of using a Bluetooth cellular phone is that it can remain in your laptop carrying case or pocket, and a Bluetooth cellular phone does not require a direct line of sight connection. If your laptop is not already Bluetooth enabled, you can purchase a USB Bluetooth adapter.

A Bluetooth cellular phone makes it easy to transfer or receive information from other Bluetooth-enabled devices, eliminating the need for extra cables. A Bluetooth cellular phone can be used with a Bluetooth-enabled headset allowing for handsfree operation. You can put the Bluetooth cellular phone in your pocket or carrying case and still take calls. This is especially useful if you need to use your Bluetooth cellular phone while driving.

Be secure

As with any wireless device, a Bluetooth cellular phone has some minor security concerns. The SIG has admitted that bluebugging, where a hacker secretly accesses a phone's commands (such as eavesdropping on conversations), and bluesnarfing, where a hacker can access a phone's data--such as the contacts--are possible, yet the group downplays both actions. While they work through Bluetooth, they also require the hacker to use a PC and to be within range of the victim's Bluetooth cellular phone (10 meters). Still, Nokia and Sony have said these issues affect only older handsets that are available mainly outside of the United States, and Nokia is promising a software upgrade. To help combat both, a Bluetooth cellular phone can be locked with a code or simply turned off or put in hidden mode when not in use. Another concern, depending on how you look at it, is bluejacking. This often involves creating a flirtatious introductory message, then sending it to another Bluetooth cellular phone (that is discoverable) narby as a text message.

History of Cellular Phone

In today's world, most people communicate through the use of cellular phones. It's hard to believe that fifteen years ago cell phones were a rarity. Below is a history of cellular phone chronicling the dawn of the cell phone to its current state.

Samuel Morse Invents the Telegraph

Any history of cellular phone starts with Samuel Morse. He conceived an electromagnetic telegraph in 1832 and constructed an experimental version in 1835. Then, on October 18, 1842, Morse laid wires between Governor's Island and Castle Garden, New York, a distance of about a mile. Part of that circuit was under water because Morse wanted to show that an underwater cable could transmit signals as well as a copper wire suspended on poles. But before he could complete this demonstration a passing ship pulled up his cable, ending, it seemed, his experiment. However, undaunted, Morse proceeded without the cable, passing his telegraph signals through the water itself. This introduced the concept of wireless by conduction, which can be considered as the first event in the history of cellular phone. Quite simply, Samuel Morse's telegraph was the first device to send messages by electricity and marked a turning point in the history of cellular phone.

1843 - This year marked the second major event in the history of cellular phone. A skilled analytical chemist by the name of Michael Faraday began exhaustive research into whether space could indeed conduct electricity, using the principles already established by telegraphy. His discoveries have had an incalculable effect on technical development toward cellular phone development and his contribution can never be excluded when scripting the history of cellular phone.

1865 - The next record in the history of cellular phone, Dr. Mahlon Loomis of Virginia, a dentist, may have been the first person to communicate through wireless via the atmosphere. He developed a method of transmitting and receiving messages by using the Earth's atmosphere as a conductor and launching kites enclosed with a copper screens that were linked to the ground with copper wires. This scripted a major chapter in the history of cellular phone.

1973 - Dr Martin Cooper's contribution is worth mentioning in the history of cellular phone, he is considered the inventor of the first portable handset. Dr. Cooper had a major part to play in the history of cellular phone. He was a former general manager for the systems division at Motorola, and the first person in the history of cellular phone, to make a call on a portable cellular phone.

1977 - Another major happening in the history of cellular phone. Cell phones go public, with the first working prototype of a cell phone in the history of cellular phone, being the Motorola Dyna-Tac. Public cell phone testing began. The city of Chicago was where the first trials began with 2000 customers, and eventually other cell phone trials appeared in the Washington D.C. and Baltimore area. Japan began testing cellular phone service in 1979. This was the first time ever in the history of cellular phone that people got a look at this new technology.

1988 - This year, in the history of cellular phone, changed many of the technologies that had become typical in the past. The Cellular Technology Industry Association (CTIA) was developed to lay down practical goals for cellular phone providers. This included research for new applications for cell phone development.

In spite of the unbelievable demand, it took cellular phone service 37 years total to become commercially accessible in the US. According to the Cellular Telecommunications Industry Association, today there are more than 60 million customers with cellular phones, even though wireless service was just invented nearly 50 years ago.

GSM Cellular Phone

A GSM cellular phone is a type of cellular phone that uses the (G)lobal (S)ystem for (M)obile Communications to send and receive phone calls. GSM is a digital standard; first offered commercially in 1991 and is currently the most popular mobile phone transmission technology in the world.

The GSM standard uses TDMA digital technology, which allows for three different voice calls to be placed in the same time slot, rather than one call using the old analog cellular phones. This is possible through digital compression, which GSM then builds upon with the addition of encryption. A GSM cellular phone takes up the same amount of transmission space as the old technology, but has the additional benefit of added security.

One of the great benefits of a GSM cellular phone is the addition of a SIM card, or "Subscriber Identification Module." This little chip slips into the back of a GSM cellular phone and provides all of the users' personal information. This includes contacts and calendar information in most cases, and more importantly the subscriber's personal identification information. Having this information on a removable chip enables a GSM cellular phone user to move a SIM card between cellular phones and still receive voice calls to the same number. It also prevents user from having to re-input personal information each time a new phone is purchased.

GSM Cellular Phone Advantages

A GSM cellular phone offers superior sound quality. Background sounds, disturbances, and static sounds are vastly reduced; and crossed-line conversations are also almost eliminated in a GSM cellular phone. GSM cellular phone sound quality is more like that of a fixed telephone. The main advantages of a GSM cellular phone are International Roaming ability, good sound quality, small affordable handsets and ability to handle a high volume of users. Unlike analog phones, your conversation using a GSM cellular phone within the digital network is safe and secure.

With superior battery life & digital technology of a GSM cellular phone, you get twice as much talk time from each battery charge, compared with analog phones. In addition, the digital service offered by the GSM cellular phone network, allows more calls to be handled at any one time, therefore reducing congestion in areas of dense population and high usage.

A GSM cellular phone offers roaming facility, which means, you can use your GSM cellular phone, with the same phone number in other countries around the world that operate through the GSM cellular phone network or you can just move your SIM card to another GSM cellular phone.

In Europe and most of Asia, GSM is the standard used by everyone. Having one technology is great, because users can simply move their chips to a different GSM cellular phone if they travel to different countries or in most cases use the same phone. This is in contrast to the US, with so many competing standards and difficulty transferring between carriers.

The adoption of GSM technology and GSM cellular phones as a standard also paved the way for the rise of text messaging in many countries. While text messaging is starting to become popular in North America, it is nowhere near as popular as it is in Europe and Asia. Carriers in the US in particular use various technologies in addition to GSM and must then route text messages through third party gateways. This is how a Sprint user can send a text message to a Verizon customer. Until a few years ago this wasn't possible and served to prevent text messaging from truly catching on.

GSM and GSM cellular phones have found a significant boost due to Cingular Wireless becoming America's largest mobile provider. They have adopted GSM technology and promote the GSM cellular phone's ease of use due to a swappable SIM card. Though the US still has many competing technologies, a GSM cellular phone is the international choice. If you plan to travel frequently overseas, a GSM cellular phone might be a wise decision.

The GSM standard has been around for a relatively long time. Its popularity continues to grow because of the addition of GPRS and integration of cameras, MP3 players and other gadgets into a GSM cellular phone. Modern GSM cellular phones support the creation of text and picture messages. Because of these additions, this relatively old standard is actually being phased in within the US.

Cellular Phone Ringtone

A cellular phone ringtone is a sound file that is played by a cellular phone. The facility was originally provided so that people would be able to determine when their phone was ringing when in the company of other mobile phone owners.

Cellular phone ringtones are melodic sounds a cellular phone makes when an incoming call or message arrives. Since cellular phones are significantly more sophisticated than most landline phones, cellular phone ringtones can be personalized to suit the owner's personal taste.
