The price of a cell telephone has skyrocketed over the past decade, with the average cost of a basic handset doubling between 2009 and 2014, according to a new report.

But the cost of buying a phone in the U.S. has not kept up with that increase, and in fact, it has decreased by more than half since 2009, according the National Geographic Society.

“Cell phones are more expensive than cars because they’re a much smaller piece of equipment,” said David A. Stuckey, the organization’s executive director.

“The main thing you want to do is go to a carrier that has a great price and a great network, and you want it on your phone at a very reasonable price.

The reason why cell phones have gotten so expensive is because the carriers have a monopoly on them.”

The average price of the phone with the best network in the United States is currently $299, while the cheapest option is $70.

The price per gigabyte has also risen by nearly two-thirds since 2009.

The National Geographic study looked at prices for the top 5 percent of smartphones sold worldwide, and found that prices for premium smartphones in the last few years have been around 40 percent more expensive, while in the past, they were around 30 percent more.

The report also said that in some countries, the price of premium smartphones has dropped by 20 percent in the same period.

The average cost for a smartphone with a 5 megapixel camera has also increased by about 60 percent since 2009 while the cost for the same smartphone with 4 megapixel cameras has increased by 40 percent.

For a premium smartphone, that translates to $7,800, according a new study from market research firm Kantar Worldpanel ComTech.

For the same model, the average price is $2,600.

But that difference is small compared to the difference in the average amount that a premium phone costs.

For example, a $2.5 million iPhone costs about $2 million.

For an iPhone 5, a premium model with a larger camera costs $5,000.

That’s more than three times the cost, according Toomey.

“I don’t think the average person is going to care about that,” he said.

“But they do care that they’re paying more than the average consumer.”

The National Geospatial Intelligence Agency said that smartphones with high-end specs, such as the Apple iPhone 5C, are “most frequently the cheapest phones” to buy.

“This data shows that, for the most part, the cheapest smartphone in a smartphone lineup is the one that features the highest-resolution screen and the most powerful processor,” said John P. Toomeys co-author of the study, who has also studied smartphones.

Toomes co-authored a study with James G. Stokes and Peter C. Hennings titled “Who’s in Charge of Mobile Phone Prices?” that analyzed the cost to buy a smartphone in the six largest markets in the world.

In that study, Toomes and Stokes found that smartphone prices rose by about 30 percent in Mexico between 2009 to 2014.

In South Africa, they found that smartphones had the highest price increases.

In China, where the smartphone market is dominated by Huawei and Xiaomi, the most expensive smartphones were those from China Mobile, which has an estimated market cap of more than $70 billion.

The researchers also found that most smartphone prices in India are between $300 and $500.

In Mexico, Mexico City, and the Dominican Republic, they said that prices increased by more about 30 to 40 percent between 2009-2014.

In Brazil, where they also analyzed prices, the study found that average prices increased about 30 and 40 percent in that country.

In Canada, they also found the most frequent smartphone manufacturers were China Mobile and Samsung.

The most frequent brand in Mexico, however, was the Chinese company Huawei.

The study found, for example, that smartphones from the top five brands rose by more in Mexico from 2009 to 2015 than they did in other countries.

For every $1 increase in the price in Mexico in the period 2009 to 2013, prices in other Latin American countries rose by a factor of 1.5.

The top five smartphone brands in Mexico rose by an average of $3,200.

For each $1 in Mexico’s price increase, prices rose in the rest of the countries examined by the researchers.

In other words, Mexico’s top five brand had the most cost-per-unit-price increases in the entire study.

But a top five iPhone brand in the study had an average price increase of $2 per unit, which was about 20 percent lower than the top six brands.

For top five Android phones, the cost-over-time average for the first two years after their introduction was about 30 cents higher than the cost per unit for the next five years.

In comparison, a top six iPhone brand had an overshoot of more that 50 percent for over the next 10 years, the researchers found
