SIM & Internet
Is Wi-Fi widely available?
Quick answer
Free Wi-Fi is common in hotels, cafes, restaurants, shopping centres and many trains and long-distance buses. Mobile coverage is excellent nationwide, with 5G in the cities.
Yes. Free Wi-Fi is normal in hotels, cafes, restaurants and shopping centres, and many intercity trains and FlixBus coaches carry it too. You will rarely be stuck without a connection in a town.
Mobile data as a backup
Mobile coverage is strong across the country, with 4G everywhere and 5G in the cities, so a cheap local SIM or eSIM gives you reliable data on the move. That matters for maps and transport apps when public Wi-Fi is patchy. On open networks in stations and cafes, avoid banking without a VPN.
