Wifi & Internet
The internet in Germany is quite excellent (though you may be disappointed if you are used to vacationing in Eastern Europe). The internet speeds, like those in most of Western Europe, are adequate but occasionally annoying. I'd rate the German internet I've used as superior to that of Spain and France, far superior to that of Greece, and far inferior to that of Bulgaria and Serbia.
This is simply my personal view based on my own experiences. Germany's mobile internet is now ranked #42 in the world, and their broadband is ranked #25. Many restaurants, cafes, and train stations offer free Wi-Fi. Although it isn't ubiquitous, I was able to find something when I needed it.
Throughout exchange for your e-mail and other data, you can access over 56.000 free WiFi hotspots in Germany. These hotspots can be found at airports, cafés, train stations, and throughout the city center.
They are usually labeled as Wifi or in German WLAN pillars. Instead of rushing up and down the street looking for them, you may utilize a service called WiFi Map to assist you find them. It's a map-based tool that lets you identify and connect to accessible hotspots more quickly.
