SEOUL – North Korea is evading U.N. sanctions by profiting on the soaring domestic demand for smartphones, according to defectors, experts and an analysis of North Korean-made phones.
Economists estimate as many as 6 million North Koreans — a quarter of the population — now have mobile phones, a critical tool for participating in an informal market economy that has become a key income source for many.
Reuters spoke to some 10 defectors and experts about the use of mobile devices in North Korea, as well as reviewing state media reports and advertisements for mobile devices and examining two North Korean-branded smartphones.
The phones feature Taiwanese semiconductors, batteries made in China and a version of Google’s open-source Android operating system.
United Nations sanctions imposed in 2017 because of the North’s weapons programs prohibit imports of mobile phone hardware.
Leader Kim Jong Un has endorsed wireless networks — some reportedly built with the help of China’s Huawei Technologies — and local mobile phone brands through speeches and a tour to a mobile phone factory reported by state media.
Basic North Korean phones typically cost between $100 and $400 at state stores or private markets, experts and defectors say. Subscriptions to mobile carriers are registered at the telecommunications ministry’s stores.
Phones are typically sold with service plans that include 200 minutes of calling time. Prepaid plans cost about $13 for 100 minutes, advertisements show.
North Koreans earn an average of about $100 per month, only about 4 percent of their southern neighbors, according to South Korean government data.
International brands are not publicly on sale, but traders and wealthy North Koreans can buy them outside the country and use them with local SIM cards, defectors say.
North Korean phones can only be used to call domestic numbers, and have some unique security features. Downloading or transferring files is severely restricted. Reuters found a warning pop-up when installing an “unidentified program” on the Pyongyang 2418 smartphone stating, “If you install illegal programs, your phone can malfunction or data will get destroyed.”
“North Korea puts algorithms and software in its mobile phones to keep data from being copied or transferred,” said Lee Young-hwan, a South Korean software expert studying North Korean smartphones.
Apps such as maps, games and an English dictionary show they are developed by North Korean engineers at state-run enterprises or state universities.
The regime has also developed a home-grown surveillance tool on mobile phones, according the U.K.-based cybersecurity company Hacker House.
When a user accesses illegal or nonstate approved media, an alert is generated and stored inside the phone. A modified version of Android also conducts surveillance and tracks users, Hacker House said.
Tool for business
Still, the phones are a big asset in North Korea’s gray market, which has flourished since a devastating famine in the 1990s.
One young woman surnamed Choi recalled selling two pigs and smuggling herbs from China to raise the 1,300 yuan ($180) her family needed to buy a mobile phone in 2013.
She used the phone to help run a retail business selling Chinese clothes and shampoos, arranging deliveries from wholesalers.
“It turned out we could make way more money than our official salaries,” said Choi, who has since defected to South Korea.
In a survey this year of 126 North Korean defectors who had used mobile phones, more than 90 percent said cellphones improved their daily lives and half said they used them for market activities.
“Millions of people are using mobile phones and need them to make a living or show off their wealth,” said Shin Mi-nyeo, executive director of the Organization for One Korea, a South Korean support group for defectors that conducted the poll. “Then their phone bills create huge income for the government.”
Kim Bong-sik, a researcher at South Korea’s Korea Information Society Development Institute, said estimating revenues is difficult but phones are likely to be one of the state’s biggest earners, given the scale of the business.
The two Pyongyang-branded smartphones examined are powered by chips from Taiwan’s MediaTek. Ads for an Arirang-branded handset also claimed to use MediaTek chips.
The Pyongyang 2423 smartphone manufactured last year featured Mediatek’s MT6737 chipset and a slot for one SIM card and one memory card. The memory card’s serial number showed it was produced by Toshiba.
The device’s identification number showed the phone was manufactured by the Chinese firm Gionee, a maker of low-end smartphones.
Google said any hardware maker can use Android at no cost, meaning no export rules are being violated. Mediatek said it had not shipped any products to North Korea. Toshiba also said it had no business with North Korea.
“North Korea cannot make phones without using foreign components and technology,” said researcher Kim. “That means it is violating sanctions to keep running the business.”
Official customs data show North Korea imported $82 million worth of mobile phones from China in 2017, the biggest import item after soybean oil and fabrics.
That number dropped to zero in 2018 as sanctions bit.
But although sanctions eliminated official imports, informal trade along the China-North Korea border appears to be ongoing, experts and defectors say.
William Brown, a retired U.S. intelligence official who studies North Korea said mobile phone hardware parts “are very easily smuggled across the Chinese border.”
Intermediaries make it hard to find those responsible for breaching sanctions, he added.
China is North Korea’s sole major ally, and its mobile phone industry is crowded with little-known local smartphone manufacturers.
Big Chinese telecommunications brands have previously supplied North Korea as well.
Huawei supplied 3G network equipment to North Korea after the late leader Kim Jong Il, the father of Kim Jong Un, toured the Chinese tech giant in 2006, according to the Nautilus Institute in the U.S. and the monitoring group 38North.
The U.S. Commerce Department has been investigating Huawei since 2016 and is reviewing whether the company violated export control rules in relation to sanctions on North Korea, sources have said.
ZTE Corp. agreed last year to pay a $1 billion fine for violating U.S. sanctions involving shipment of telecom equipment to Iran and North Korea.
