Mobile phone - Wikipedia
A study reviewed the incidence of mobile phone use while cycling and its effects on behaviour and safety. Accidents involving a driver being distracted by talking on a mobile phone have begun to be prosecuted as negligence similar to speeding. New Zealand has banned hand-held cell phone use since 1 November Many states in the United States have banned texting on cell phones while driving. Illinois became the 17th American state to enforce this law. This database of laws provides a comprehensive view of the provisions of laws that restrict the use of mobile communication devices while driving for all 50 states and the District of Columbia between when first law was passed, through 1 December The dataset contains information on 22 dichotomous, continuous or categorical variables including, for example, activities regulated e.
In , an estimated pedestrians were injured in the US while using a cellphone and some jurisdictions have attempted to ban pedestrians from using their cellphones.

The effect of mobile phone radiation on human health is the subject of recent [ when? Mobile phones use electromagnetic radiation in the microwave range, which some believe may be harmful to human health. A large body of research exists, both epidemiological and experimental, in non-human animals and in humans. The majority of this research shows no definite causative relationship between exposure to mobile phones and harmful biological effects in humans. This is often paraphrased simply as the balance of evidence showing no harm to humans from mobile phones, although a significant number of individual studies do suggest such a relationship, or are inconclusive.
Other digital wireless systems , such as data communication networks, produce similar radiation. On 31 May , the World Health Organization stated that mobile phone use may possibly represent a long-term health risk,   classifying mobile phone radiation as "possibly carcinogenic to humans" after a team of scientists reviewed studies on mobile phone safety. Some recent [ when? Lennart Hardell and other authors of a meta-analysis of 11 studies from peer-reviewed journals concluded that cell phone usage for at least ten years "approximately doubles the risk of being diagnosed with a brain tumor on the same 'ipsilateral' side of the head as that preferred for cell phone use".
In May , preliminary findings of a long-term study by the U. A study by the London School of Economics found that banning mobile phones in schools could increase pupils' academic performance, providing benefits equal to one extra week of schooling per year. The average user replaces their mobile phone every 11 to 18 months,  and the discarded phones then contribute to electronic waste.
Mobile phone manufacturers within Europe are subject to the WEEE directive , and Australia has introduced a mobile phone recycling scheme. According to the Federal Communications Commission , one out of three robberies involve the theft of a cellular phone. All mobile phones have a unique identifier called IMEI. Anyone can report their phone as lost or stolen with their Telecom Carrier, and the IMEI would be blacklisted with a central registry.
There are, however, a number of ways to circumvent a blacklist. One method is to send the phone to a country where the telecom carriers are not required to implement the blacklisting and sell it there,  another involves altering the phone's IMEI number. New standards beyond 4G are currently being developed by standardization bodies, but they are at this time seen as under the 4G umbrella, not for a new mobile generation.
Demand for metals used in mobile phones and other electronics fuelled the Second Congo War , which claimed almost 5. The profits from the minerals finance the bloodiest conflict since the second world war; the war has lasted nearly 20 years and has recently flared up again. For the last 15 years, the Democratic Republic of the Congo has been a major source of natural resources for the mobile phone industry.

Last September, T-Mobile eliminated all of its traditional plans with specific data quantities, subbing in a single, competitively priced unlimited plan: Finally, in early , Verizon caved as well. The resurgence of unlimited plans has brought other shifts, experts say. The Big Four have sharply cut the number of plans they offer—to 35 from the 49 offered a year ago. It simplifies the choice for heavy data users. The major carriers have also cut prices for those unlimited plans, making them more practical for more people.
We compared cost per gigabyte, hidden fees, and national network quality, as well as data limits and speeds. We also ruled out providers who failed to meet our thresholds for customer service, data, and voice network quality. See the full methodology here. For this category, we looked at plans with less than 4GB of data. The backbone of Republic Wireless is hybrid calling, a technology that seamlessly transfers users between Wi-Fi and cellular networks for voice calls.
Smartphone users now generally consume about 4. You also save by going with a prepaid plan, since those charge lower taxes and fees. This plan caps download speeds, which means the network may feel like a slower 3G connection. And it defaults to streaming video in standard definition to save on data.
Despite the name, even unlimited plans may stumble on poor connections or data usage restrictions. The plan also works well for travelers, as it includes unlimited texting and data abroad, plus an hour of Gogo Wi-Fi on every flight. If you and your partner are both average users, you can probably save some cash by signing up for one plan with two lines. Cricket also has an above-average customer service score from J.
