Power & Connectivity (SIM)
Connectivity may vary by region and season.
Voltage & Plug Types
Electrical standards and outlet shapes
Denmark uses 230V / 50Hz with Type C, E, F and the Danish-specific Type K sockets (European round pins). A Type C plug fits most sockets; bring a Type C/E/F adapter. Travellers from 100–120V countries need a converter for devices that are not dual-voltage.
