Is there a way you can reasonably use that data offer to a large extent? For example, I know my provider has a setup where you can register your device MAC, connect to their city-wide wifi, and then it will let you use your data as wifi. In this scenario if it's really unlimited, is there a way you can chain devices together to get something crazy like 20Gbps up/down and do a bunch of heavy operations 24 hours a day on that for a few days? Warning: I imagine if you do this they will say "it's not really unlimited bro that's not that we meant"
