This specific CheapESIM plan is valid exclusively within Finland. Many travelers enjoy taking scenic ferries from Helsinki to Tallinn (Estonia) or overnight cruises to Stockholm (Sweden). However, once your ferry departs Finnish territorial waters, your internet connection will cease. To maintain seamless connectivity throughout your multi-country journey, including international waters and neighboring countries, we recommend exploring our regional or multi-country eSIM plans. These options provide continuous coverage and better value for combined travel itineraries, avoiding connectivity gaps.
