This specific eSIMFlyer plan is designed exclusively for use within Finland. Many travelers enjoy the popular ferry routes from Helsinki to Tallinn (Estonia) or the overnight cruise to Stockholm (Sweden). However, once your ferry departs Finnish territorial waters, your connection will transition to maritime roaming or cease entirely, depending on your exact location. For uninterrupted connectivity across the Baltic Sea and into neighboring countries, we recommend opting for a regional Nordic & Baltic eSIM or a broader European plan from eSIMFlyer, ensuring you're always online, even mid-voyage.
