How can it be a scam?

Unless T-Mobile are quietly laundering most of back to them?

I have no idea though why they agreed such a daft penalty.

I wonder what T-mobile / Deutsche Telekom will do with it? You could almost do FTTH for small country like Ireland with that and have enough left for Urban /Suburban LTE for 80% of Irish Population.

Or do 1/2 of Brooklyn.
