Skip expensive tourist transport passes. STB cards at any metro station: 8 RON gets unlimited daily transit including M4 airport line. Orange shops everywhere for longer stays — 15 RON gets 10GB EU-wide, but STB card better value for Bucharest-focused trips under one week.

Bring passport for Orange registration. STB cards work immediately, contactless payment accepted. Better than expensive airport shuttle services to Henri Coandă.
