It can certainly be much cheaper. I pay 17€/month for "unlimited" LTE (includes 9GB EU roaming) and this at ~75 Mbit/s up/down speeds in most cases. Now it's hard to say what "unlimited" actually means in numbers, as it's just defined as reasonable usage in the terms of service. However as another data point, the next cheapest plan is 100GB LTE for 15€/month, so I assume unlimited is at the very least above 100GB.
