Airport WiFi at CGN
Registration required to connect — look for the sign-in page after joining the network.
Germany's 4G/5G coverage from Deutsche Telekom, Vodafone, and O2 is strong right at the terminal — any EU-roaming SIM works at full speed with no surcharge, and mainstream eSIM providers (Airalo, Holafly) cover the airport and city with no physical SIM needed.
Connecting only takes an email address and accepting the terms — no phone number or SMS code — so it's one of the quicker captive portals in Europe if you don't already have EU roaming or a local eSIM ready to go.
