Traveling in Europe: Where can I find a free wifi wireless network?

There are 66 WIFI hotspots in the railway station, the platform in front of the dock and the square to send "24-hour free wireless network, speed 1Mb per second". But in the subway, only three underground stations are covered. The same is true of subway stations in European capitals. Generally, there are few terminals that provide users with free WIFI signals, but they are easy to find on buses and trains. When you are on vacation in Europe, if you don't have a monthly international call plan and don't want to be scared to the ceiling when you receive the bill, here is a list of places where you can connect to free WIFI. In Spain, there is no WIFI coverage in the subway, but all buses in Madrid have wireless network coverage, which was provided by Gowex Company and was fully launched on September 20 10. Still in the capital, more than 60 tourist buses to and from surrounding cities also cover free WIFI. The double-decker sightseeing buses in Madrid and Barcelona are equipped with Gowex WIFI devices. In Britain, in early June, several London subway stations were covered by WIFI, and about 80 subway stations will be covered in the future. In Portugal, Carris in Lisbon has two bus lines providing free WIFI, while STCP in Porto is experimenting with free WIFI on one of their bus lines. Rede Nacional de Expressos, a private intercity bus company, provides its own free WIFI service. On the subway in Lisbon, Portugal Telecom Group set up a free WIFI network at Baixa-Chiado station. In Austria and Vienna, there is no WIFI network on public transportation. On the railway side, the Austrian state-owned railway company BB provides free WIFI on all Railjet high-speed trains, while its competitor Westbahn provides free WIFI on all trains. In Sweden, all high-speed trains and SJ2000 intercity trains have free WIFI. In Stockholm, to be exact, in 2008, there was a free WIFI test on the bus, but there was no follow-up. Obviously, there are too many people signing up for mobile phones. In Finland, the state-owned railway company provides free WIFI on almost all intercity trains. Helsinki's subway (only one line) can also be fully connected. As for the tram in the capital, an experiment was conducted in 2007, but it did not continue. In Norway, most trains have free WIFI. However, there is no signal coverage on the subway or bus in Oslo, but there are some long-distance passenger buses or airport buses.
