Power & Connectivity (SIM)
Connectivity may vary by region and season.
Voltage & Plug Types
Electrical standards and outlet shapes
Finland uses 230V / 50Hz with Type C and Type F sockets (European two round pins). Bring a Type C/F adapter; travellers from 100–120V countries need a converter for devices that are not dual-voltage.
