EU roaming rules only cover SIM cards from EU and EEA countries. Check your operator's rates or buy a local eSIM.
Documents
Passport required
Visa-free for up to 90 days in any 180; your passport must be valid for at least 3 months after you leave. Check the current Schengen entry rules (EES, ETIAS).

Your UK GHIC is valid
It covers public healthcare in the EU — travel insurance is still recommended.
