This particular SouthESIM plan is specifically designed for use within Finland. If your journey includes a scenic ferry ride from Helsinki to Tallinn (Estonia) or an overnight cruise to Stockholm (Sweden), your data connection will typically cease once you leave Finnish territorial waters. For travelers planning to visit multiple Nordic or Baltic countries, we recommend exploring our regional eSIM options for continuous, hassle-free connectivity across borders.
