No, there are currently no unlimited data eSIM plans available for North Korea due to the country's stringent internet restrictions and the very limited access for foreign visitors. The North Korean government heavily controls all forms of communication, making widespread mobile internet services for tourists virtually non-existent, and therefore, no eSIM providers offer such plans.
Travel to North Korea is also highly restricted, and independent tourism is not permitted. Visitors typically travel in supervised tours where internet access remains extremely limited, if available at all, usually through highly regulated and expensive local SIM cards with minimal data allowances. Therefore, an 'unlimited data eSIM' for North Korea is not a realistic option.
