The Atmosphere of Slush in Helsinki

Slush transforms Helsinki into a vibrant hub of energy. Messukeskus becomes the center of attention, but the entire city buzzes with activity. Investors gather in hotels, founders meet in cafés, and side events run late into the night.

The atmosphere is unlike traditional conferences – casual, collaborative, and inclusive. Attendees are encouraged to engage openly, creating an environment where partnerships flourish naturally.

Moving Around Helsinki During Slush

With more than 20,000 participants in town, transport becomes a key part of the Slush experience. Luckily, Helsinki’s infrastructure makes it easy to get around, whether you are heading to Messukeskus, attending a side event in the city, or exploring during your downtime.

• Public Transport: Trams, buses, metro, and commuter trains are all connected under the HSL system. A single ticket allows transfers, making navigation simple.
• Trains from the Airport: Helsinki-Vantaa Airport connects to the city center in about 30 minutes, with direct routes toward Pasila, the area where Messukeskus is located.
• Rideshare and Taxis: Uber and Bolt operate in Helsinki alongside traditional taxis. These are reliable but can be slower than trams during peak times.
• Walking and Cycling: Helsinki is compact and designed for pedestrians and cyclists, making shorter commutes easy on foot.

Being able to check schedules and maps on the go is essential. That’s why many attendees rely on strong mobile connectivity to manage their movement across the city.

Why Internet Connectivity Is Essential During Slush?

At Slush, opportunities happen by the minute. Whether you are a founder, an investor, or media covering the event, reliable internet access ensures you never miss an important connection.

• Scheduling: The official Slush app provides live updates and personalized agendas, requiring constant access.
• Networking: Investors and founders often finalize meetings on short notice, so messaging apps are crucial.
• Navigation: Side events are scattered across Helsinki, making maps and transport apps invaluable.
• Social Sharing: Attendees document their experiences in real time, sharing photos, insights, and highlights.
• Work on the Go: For many, Slush is also a working trip. Presentations, pitch decks, and contracts often need to be sent instantly.

Without reliable mobile data, these activities can quickly become stressful and inefficient.

Why an eSIM for Finland Makes Travel Easier?

For international attendees, one of the simplest solutions is activating an eSIM for Finland before departure. Unlike traditional SIM cards, an eSIM does not require picking up a card, standing in queues, or dealing with paperwork at the airport. Instead, it activates in minutes by scanning a QR code, making your phone ready as soon as you land.

For Slush attendees, this means more time to focus on their agenda. No detours to kiosks, no unexpected roaming bills – just reliable data for every meeting, event, and exploration.
