Mobile data and Germany are mutually exclusive…
For mobile I’m on a prepaid plan for 7.99 €/28days, limited to 21MBit/s in 4G networks, unlimited in 3G (but those are in a process of beeing shut down). It is limited to 3GB of transfer (meaning 3,000,000,000 bytes). After that I’m limited to 64kbit/s. Though as I’m usually in range of personal or free WiFi I rarely hit those 3GB anymore.
I have free internet on any Vodafone provided WiFi access point (in Germany at least, not sure about abroad) due to participating in the Vodafone Neighboorhood program… Hamburg is pretty well coverd and as long as I’m stationary, I can use those hotspots.
. Hopefully the connectors don’t corrode away again before 5G hits our area.
