Thats because you will limited unless you use specific services.
In Germany, two operators (T-Mobile and Vodafone) offer special "passes" for different services. These do not count against your monthly quota (if you use up all your data, you will be limited to about 64 kbit/s).
So, yes, you can use a VPN, but this will count against your data cap. While, if you use the services they choose for you, you basically get "free" extra data.
