North Korean authorities in North Pyongan province have dramatically escalated phone surveillance operations throughout 2026. The National Intelligence Agency now intercepts both landline and mobile calls to catch traders conducting cross-provincial business. Consequently, growing numbers of residents avoid phone calls altogether, meet in person, or speak in coded language. The intensified phone surveillance has created widespread anxiety across entire communities of traders and ordinary citizens alike.
The crackdown traces directly to a specific incident around June 10 in Kusong city. NIA agents intercepted a call between a gold trader and a contact in Ryanggang province. During that call, the trader received a money transfer broker’s contact details and address. Agents then tracked the phone number, investigated the broker first, and subsequently raided the trader’s home without warning. The raid resulted in the seizure of tens of thousands of US dollars in foreign and domestic currency, and authorities detained both the broker and trader in sequence.
News of the arrests spread rapidly throughout North Pyongan province and accelerated existing wariness about communication. Residents now openly state that the NIA monitors every call on both landlines and mobile networks. Furthermore, traders whose businesses depend on phone-based coordination of goods, transport, and payments face a particularly difficult dilemma. Sources describe mobile phones as a time bomb that traders cannot afford to carry yet cannot operate without.
Some residents have attempted to obtain SIM cards registered under other people’s names to evade identification during calls. However, sources warn this workaround offers limited protection because authorities can still trace call content and contacts regardless of the registered identity. Additionally, mobile phones carry an extra risk because authorities can track users by physical location in addition to monitoring conversations directly.
Going forward, the escalating phone surveillance leaves North Korean traders with no reliable solution to protect their communications. Sources indicate the NIA openly warns residents that authorities monitor and record everything. Ultimately, the crackdown threatens to severely disrupt informal trading networks that millions of ordinary North Koreans depend on for their daily economic survival.
