Power & Connectivity (SIM)
Connectivity may vary by region and season.
Voltage & Plug Types
Electrical standards and outlet shapes
Czechia uses 230V / 50Hz with Type C and Type E sockets (French style, with an earth pin). Bring a Type C/E adapter; travellers from 100–120V countries need a converter for devices that are not dual-voltage.
