Wi-Fi is widely available in most hotels, cafes, and restaurants across the Mediterranean, but expect varying speeds. Cellular coverage is generally robust, especially in urban areas like Nice, Monaco, and Barcelona, with 4G being standard. For extended access, consider purchasing a local SIM card upon arrival, which can provide better rates than international roaming. Power outlets typically use Types C and F, with a voltage of 230V; make sure to bring a plug adapter to charge your devices.
