When visiting Gothenburg, it's helpful to know that the city has extensive Wi-Fi available in public spaces, making it easy to stay connected. If you need mobile data, consider purchasing a local SIM card from convenience stores. For public transport, the Västtrafik card is a great option, allowing unlimited travel on buses, trams, and ferries within the city. You can buy this card at service centers or convenience stores, and it's also available through a mobile app that helps plan your routes. Remember that most public transport services require you to purchase tickets in advance, as you can't buy them from drivers. Additionally, Gothenburg operates on Central European Time, so plan your activities accordingly. Lastly, tipping is customary, so rounding up your bill or leaving around 10% for good service is appreciated. With these tips, you'll navigate Gothenburg smoothly and enjoy your stay!
