This just happened in Belgium. One of the networks was reselling through the biggest internet and tv provider. It seemed like a sweet deal, since they were getting most of the revenue and had almost none of the support costs. Now the internet provider has bought a competing wireless network, and will move their customers over to that one instead, ending the contract. The original network provider is going to have some tough financial times ahead because they're seeing 20% of their customers walk out the door all at once.
