Call Democratic People's Republic of Korea from Cambodia

The telecommunications infrastructure in the Democratic People's Republic of Korea (DPRK) is heavily regulated and state-controlled. There are limited mobile network operators, primarily Koryolink, which was established in 2008 as the first and only commercial mobile phone service provider in the country, and it operates on a 3G network. As of recent reports, the 4G network is available in select areas, particularly in the capital, Pyongyang, but 5G services have not been rolled out. Landline infrastructure exists, but it is primarily restricted to government and state-run entities, making widespread access for civilians rare.

Mobile phone usage is gradually increasing, primarily among the elite and government officials, with estimates suggesting that around 4 million people have access to mobile devices. However, due to strict government censorship and monitoring, international calls and internet access are limited, creating a unique and challenging environment for communication. Overall, the telecommunications landscape in the DPRK is characterized by its isolation from the global network and stringent controls imposed by the state.

Communication culture in the Democratic People's Republic of Korea is deeply influenced by the country’s political climate and social norms. When making phone calls, it is essential to maintain a formal tone, especially during initial interactions. People typically answer calls with a standard greeting such as “Hello” or “Yes,” but the formality may vary based on the relationship between the callers. Cold calling is generally frowned upon, and it’s advisable to establish a prior connection or through a mutual acquaintance.

Business calls tend to follow a more structured format, often requiring an introduction and explanation of the call’s purpose. Personal calls may allow for a more relaxed conversation, but respect for hierarchy and social status should always be observed. Preferred communication channels often depend on the context; while phones are used, email has become increasingly popular for formal correspondence, but it is also monitored. Understanding and adhering to these norms are crucial for effective communication.

The Democratic People's Republic of Korea operates on Pyongyang Time, which is UTC+9. When planning a call, it is essential to consider the average daily schedules of North Koreans, who generally follow a structured routine. Work hours typically run from 8 AM to 5 PM, with a break for lunch around noon. It is advisable to call during mid-morning or early afternoon when individuals are likely to be at their desks.

However, national holidays should be avoided, as many businesses and government offices close during these periods. Key holidays include the Day of the Sun (April 15), celebrating Kim Il-sung’s birthday, and the Day of the Foundation of the Republic (September 9). Weekends (Saturday and Sunday) are usually non-working days, so calls should be scheduled for weekdays. Understanding these factors can help ensure that your call reaches the intended recipient at an appropriate time.

When engaging in business calls with contacts in the Democratic People's Republic of Korea, it is important to understand the local communication norms. Meetings should be scheduled well in advance, as last-minute arrangements are often difficult to accommodate. The preferred language for business communication is Korean, so if you are not fluent, consider using an interpreter to convey your message accurately.

When making initial contact, email is often favored over phone calls, as it allows for careful consideration of content and responses. If you do opt for a phone call, be prepared with a clear agenda and stick to the point to respect the recipient's time. Professional etiquette dictates that you address individuals by their titles and surnames until invited to do otherwise. Demonstrating patience and understanding of their unique situation will foster better business relationships, given the restrictions and challenges faced by businesses in the DPRK.

North Korea runs two entirely separate networks that do not connect to each other and neither connects to the global internet. The domestic Koryolink mobile network — operated as a joint venture — serves internal subscribers and cannot receive or place international calls. International calls arrive through a separate government-controlled system, primarily reaching landlines at state enterprises, embassies, diplomatic compounds, and authorized foreign-facing organizations. Pyongyang has its own landline area code (2), and other cities have their own codes, but this information is largely academic for ordinary callers abroad: the pool of numbers reachable from outside the country is extremely narrow and the calls expensive. There is no consumer mobile number you can dial internationally to reach a private citizen in the standard sense. Practically every successful international call to North Korea goes through a vetted institutional landline.

Per-minute rates to North Korea are among the highest of any country reachable by international direct dial, reflecting both the limited routing options and the handful of carriers willing to complete the connection. The cost-saving strategy here is structural rather than behavioral: keep calls short and purposeful, as there is little benefit to extended calls on lines that may be monitored or subject to abrupt disconnection. Use carriers that specialize in difficult-destination routing rather than defaulting to a standard international plan, as rate differences between providers are significant. The calls that do connect reliably tend to be during Pyongyang business hours — roughly 9 AM to 5 PM local time (UTC+9) on weekdays — since international-facing staff at institutions are present and authorized to take calls during those windows.

Cambodia has become a vibrant home for various expatriate and immigrant communities, particularly from countries such as France, the United States, Australia, and South Korea. As of 2021, the expat population was estimated to be around 30,000, with significant communities in cities like Phnom Penh and Siem Reap. Many of these residents maintain close ties with their families and friends back home, making international calls an essential part of their lives.

Countries that are frequently called include the U.S., which has a large Cambodian-American diaspora, and France, where many Cambodians have historical ties due to colonial influences. The Cambodian diaspora in the U.S. was estimated to be over 300,000 in 2020, while the French community remains active, with thousands of Cambodians living in France.

International calling holds significant emotional and practical importance for these communities. It allows individuals to maintain relationships, share life milestones, and provide support during challenging times. With a growing number of Cambodians working abroad and sending remittances back home, the need for effective communication remains a priority, reinforcing the importance of staying connected across borders.

International calling costs from Cambodia using traditional carriers can be prohibitively high, often exceeding $0.50 per minute. For expatriates and locals making frequent calls to family or business contacts abroad, these expenses can quickly add up.

Voice over Internet Protocol (VoIP) and browser-based calling platforms like Skype, Zoom, and WhatsApp have become increasingly popular due to their cost-effectiveness. VoIP services allow users to make calls using the internet, significantly reducing the per-minute costs or even offering free calls when both parties are connected online.

Cambodia's telecommunications infrastructure has improved over the years, with a steady increase in internet penetration, which reached around 42% in 2023. Mobile data availability has also expanded, with major providers offering 4G services in urban areas, making it easier for users to access VoIP services on their smartphones or computers.

For many families, international calls are not just a convenience but a lifeline that combats the emotional distance created by geographical separation. Regular communication helps families share experiences, celebrate milestones, and provide emotional support across continents.

Technology plays a crucial role in bridging this gap, with various platforms enabling video calls and instant messaging. To maintain regular calling schedules, it’s advisable for families to establish a routine that considers time zone differences. For instance, scheduling calls during evenings in Cambodia might align with morning hours for relatives in the U.S. or Europe, ensuring that everyone can participate. By embracing technology and maintaining open lines of communication, Cambodians can foster lasting connections despite the distances that separate them.
