While EastESIM focuses on Asian destinations, we understand the importance of connectivity worldwide. For Helsinki, the HSL app is indeed crucial for navigating public transport. You'll need an active data connection to purchase and display tickets for trams, buses, and the metro across Helsinki and Vantaa. EastESIM, however, is specifically designed for seamless travel across Asia, ensuring you have the best local network access when you explore countries like Japan or Thailand.
