Here's a roundup of the best tools to make low-cost international calls available out there.

N.B.: The present roundup of tools to make cheap international phone calls is still incomplete. You may want to bookmark this page (simply hit CTRL+D on your Windows keyboard or CMD+D on your Mac keyboard) as I will be adding more services in the coming weeks.

As a side note, I would always recommend to use a headset if you want superior phone call quality. Even if to make VoIP phone calls a headset is not compulsory, having an external mic and headphones can greatly help to reduce echo and ambient noise.

Free Mobile Phone SMS

That's right. You can send free SMS to any mobile phone through your PC. To send free SMS to mobile phones, you can download any online text messaging client or software or go to any website that offers the services where you can send your text messages right on your browsers.
Sending free text message to mobile phones is quick and easy. You can download the client and sign-up for the service and instantly send messages once you're done. Or you can go straight to websites that offer the services directly on their websites.

The advantage of this service is that you don't need a mobile phone to send messages. This can come extremely handy especially in areas where mobile phone signal is spotty or hard to access. As long as you have a PC/laptop/iPod/iPhone and an internet connection, you'll be able to reply to your text buddies anywhere in the world.

Most online SMS messaging also does not charge a fee for sending messages. Most of these services are free to use and recoup their costs through advertising or with a contract agreement with the mobile phone carriers. However, there are some that may charge the recipient for receiving or for replying to your messages.
Online messaging works anywhere in the world as long as you have an internet connection. It lets you send free SMS to mobile subscribers that are supported by that client. International SMS messages can be processed if your client supports messaging to carriers outside your country.
It works much the same way as instant messaging does. You go online and send messages, but instead of sending PC to PC messages, you are sending PC to mobile phone messages. Online SMS messaging has the added benefit of being able to type messages quickly and easily with a full keyboard. However, the number of characters that can be sent each message is limited to a few hundred. If you are sending a rather long message, it can take up quite a few messages to complete.
Clients also functions like an instant messaging client. If you have a buddy that also goes online, you can send them messages using your account.
While this may be free, some services may charge you for sending email or MMS.
Another benefit of using it is that you can send free SMS to mobile phones even if you yourself don't have a mobile phone. You just need to register an account and use your email when you sign-up and voila! You can start texting even without a mobile phone.
Be careful though of providing sensitive information to suspicious websites or to websites that have no clear privacy policy. Be aware that your information can be stolen and used for unscrupulous purposes. Always follow safe internet practices and never give sensitive information to untrusted vendors.
Always report problems you encounter to the correct authorities.
Use the service wisely and prudently.

Mobile Phone Dangers

Some people appear to have an almost pathological emotional attachment to their cell phones and there is a fascinating suggestion that cell radiation pulses might actually be addictive to the human brain.. We can't save those who would rather die than switch. But ethics compelled us to ensure that all reasonable people have access to the basic scientific facts.

Your cell phone is a microwave transmitter and it should bear a cancer warning! Microwave energy oscillates at millions to billions of cycles per second. The Journal of Cellular Biochemistry reports that these frequencies cause cancer and other diseases by interfering with cellular DNA and its repairmechanisms. Microwave promotes rapid cell aging. Italian scientists have recently demonstrated that cell phone radiation makes cancerous cells grow aggressively. Cordless phones marked 900 megahertz or 2.4 gigahertz emit the same dangerous microwave radiation as cell phones.

The connection between microwave exposure and cancer has been documented for years. During the Cold War, the Soviets irradiated the U.S. Embassy in Moscow , Russia , with low level, twin-beam microwave radiation. Two successive ambassadors developed leukemia. Other staffers also developed cancer, or their blood showed DNA damage, which precedes cancer.

Research by University of Washington professor Dr. Henry Lai shows brain cells are clearly damaged by microwave levels far below the U.S. government's "safety" guidelines. Dr. Lai notes that even tiny doses of radio frequency can cumulate over time and lead to harmful effects. He warns that public exposure to radiation from wireless transmitters "should be limited to minimal."

Motorola advises consumers to avoid pointing a cellular antenna toward exposed parts of the body. But independent tests show that cell phones can also leak huge amounts of radiation from the keypad and mouthpiece. This radiation deeply penetrates brain, ear and eye tissues, which are especially susceptible to microwave damage. Belt clip cases allow cell phones to deliver radiation to the liver or kidney areas when a wired, hands-free earpiece is used.

Recent studies confirm that cell and cordless phone microwave can:

·         Damage nerves in the scalp

·         Cause blood cells to leak hemoglobin

·         Cause memory loss and mental confusion

·         Cause headaches and induce extreme fatigue

·         Create joint pain, muscle spasms and tremors

·         Create burning sensation and rash on the skin

·         Alter the brain's electrical activity during sleep

·         Induce ringing ! in the ears, impair sense of smell

·         Precipitate cataracts, retina damage and eye cancer

·         Open the blood-brain barrier to viruses and toxins

·         Reduce the number and efficiency of white blood cells

·         Stimulate asthma by producing histamine in mast cells

·         Cause digestive problems and raise bad cholesterol levels

·         Stress the endocrine system, especially pancreas, thyroid, ovaries, teste

the danger of mobile for children:

A scientist has warned that children who use mobile phones are at risk of suffering memory loss, sleeping disorders and other health problems.

Dr Gerard Hyland, of the University of Warwick, said children are particularly at risk because their immune systems are less robust and are still developing.

Fears over the use of mobile phones has centred on "brain heating", but Dr Hyland said the real risk was with low intensity radiation, known as non-thermal radiation.

Dr Hyland, who is based in the physics department at the University of Warwick, said children were at risk because their skulls are smaller and thinner and radiation was able to penetrate.

'Radiation is known to effect the brain rhythms and children are particularly vulnerable,' he said.

'The body is an electro-chemical instrument with exquisite sensitivity. The effect of microwaves from a mobile phone is a bit like interference on a radio. It has an impact on the stability of cells in the body.

'The main effects are neurological, causing headaches, memory loss and sleeping disorders.'

He added: 'If mobile phones were a type of food, they simply would not be licensed because there is so much uncertainty surrounding their safety.'

HOWEVER THE CELL PHONES BECOMES ONE OF THE IMPORTANT THING IN OUR LIFE.I THING THAT WE CAN'T LIVE WITHOUT CELL PHONE OR OUR LIFE BECOME HARD.

Mobile Phone Benefits

One cannot deny the fact that cell phones (celular) happen to be one of the most sought after and popular gadgets all over the world. Be it a school going kid, or a matured office going man, who does not like to flaunt the most expensive phones?!

However, when it comes to the benefits of using cell phones, there is surely more to them than just the prestige value. It is not just a fashion accessory, which allows staying connected with the world no matter where you are they are surely more than that.

Initially when cell phones (celular) were just introduced in the market, they were known for the wireless technology and the sms facility it provided. These devices provided the benefits of storing your phonebook entries, and allowed the users to check date and time. These could be used as calculators too, and served as a convenient way of remembering appointments when you put up a reminder on them.

However now not only have these facilities become more advanced, with lots of new features having been added to it (such as sending picture sms, mms clips, saving a larger number of phonebook entries, with especial tunes and pictures assigned for each caller, etc), now it is also possible to use cell phones for a number of other purposes too, such as for checking your mails, for using the internet, or as a mini laptop, with almost all necessary features of the computer included in it.

However, these features are only limited to those cell phones (celular) that come with heavy price tags. For the more modest ones, one can choose from devices that allow taking pictures, videos, listening to music etc. These facilities have been especially enhanced with the Bluetooth and infrared technology, which allows the user to transfer and exchange data including not only music, but also pictures, videos and sounds in a span of just few seconds.

Besides the benefits of the latest technology to users, cell phones (celular) also tend to play a vital role in helping in dealing with crime. This is primarily because it makes it easy to trace people, thru the use of the Global Tracking System (GPS), when they need to be traced down. Also, the law determines the rules that must be followed by the phone companies while providing tracking services and making cell phones and sim cards great forensic evidences in times of need.

Cell phones have been found to be of great help also in emergency situations and in times of disasters and natural calamities. These days most cell phones allow users to make `emergency calls`, so that such situations can be easily dealt with. For instance there have been a number of cases where people struck with disasters such as landslides and earthquakes have found way for themselves with the use of their devices.

With the quick development in technology, cell phones (celular) are surely becoming more and more popular with each passing day. The latest models are able to attract new market and customers, and its fast technological development can be well understood from the fact that it was just about 20 years ago, when these devices were viewed as expensive luxuries, meant for large business houses, the police force and army, and now almost 50% of all children in America own cell phones. In fact even in developing countries the use of cell phones is growing immensely, with people using it for both personal and business purposes.

Cell phones (celular) surely will have many new features in the near future!

Cell Phone invention

Today's communications industry would not be what it is without the contributions made by Richard H. Frenkiel and Joel S. Engel. The big breakthrough came when AT&T Labs researchers Frenkiel and Engel divided wireless communications into a series of cells, then automatically switched callers as they moved so that each cell could be reused. This led to the development of cellular phones and made today’s mobile communications possible.

On June 17, 1946 a driver in St. Louis, Missouri., pulled out a handset from under his car's dashboard, placed a phone call and made history. It was the first mobile telephone call. A team including Alton Dickieson, H.I. Romnesand D. Mitchell from Bell Labs, worked more than a decade to achieve this feat. By 1948, wireless telephone service was available in almost 100 cities and highway corridors. Customers included utilities, truck fleet operators and reporters. However, with only 5,000 customers making 30,000 weekly calls, the service was far from commonplace.

That "primitive" wireless network could not handle large call volumes. A single transmitter on a central tower provided a handful of channels for an entire metropolitan area. Between one and eight receiver towers handled the call return signals. At most, three subscribers could make calls at one time in any city. It was, in effect, a massive party line, where subscribers would have to listen first for someone else on the line before making a call.

Expensive and far from "mobile", the service cost $15 per month, plus 30 to 40 cents per local call, and the equipment weighed 80 pounds. Just as they would use a CB microphone, users depressed a button on the handset to talk and released it to listen.

Improved technology after 1965 brought a few more channels, customer dialing and eliminated the cumbersome handset. But capacity remained so limited that Bell System officials rationed the service to 40,000 subscribers guided by agreements with state regulatory agencies. For example, 2,000 subscribers in New York City shared just 12 channels, and typically waited 30 minutes to place a call. It was wireless, but with "strings" attached.

Something better — cellular telephone service — had been conceived in 1947 by D.H. Ring at Bell Labs, but the idea was not ready for prime time. The system comprised multiple low-power transmitters spread throughout a city in a hexagonal grid, with automatic call handoff from one hexagon to another and reuse of frequencies within a city. The technology to implement it didn't exist, and the frequencies needed were not available. The cellular concept lay barron until the 1960s, when Richard Frenkiel and Joel Engel of Bell Labs applied computers and electronics to make it work.

AT&T turned their work into a proposal to the Federal Communications Commission (FCC) in December 1971. After years of hearings, the FCC approved the overall concept, but licensed two competing systems in each city.

Modern mobile telephony took a giant leap forward on April 3, 1973, when Motorola employee Martin Cooper placed a call to rival AT&T's Bell Labs while walking the streets of New York City talking on the first mobile telephone, a Motorola DynaTAC.

In 1978, AT&T conducted FCC-authorized field trials in Chicago and Newark, N.J. Four years later, the FCC granted commercial licenses to an AT&T subsidiary, Advanced Mobile Phone Service Inc. (AMPS). AMPS was then divided among the local companies as part of the planning for divestiture. Illinois Bell opened the first commercial cellular system in October 1983.

For their pioneering work in cellular telephony, AT&T Labs researchers Richard Frenkiel and Joel Engel earned the National Medal of Technology. Cellular telephony has spawned a Multi-billion dollar industry and has freed tens of millions of people, both at home and at work, to communicate anywhere, any time.
