Well, this is a bit underwhelming. We've been waiting for some time for T-Mobile to unveil their own branded TV service and, for now anyway, they're basically just re-branding the Layer3 TV service that they've owned for a year or two.
Based on what T-Mo had said in the past, I was expecting that their service would be nationwide OTT, able to run on any internet connection. But that's not how Layer3, or TVision, works, for now anyway. They have to have an agreement in place with your home broadband provider in order to run over that connection. (Q: Does the data consumed in using this service count against whatever data cap you might have with your broadband provider?) Surely T-Mo plans to eventually offer TVision over their own wireless home broadband service, assuming that ever really launches in a big way, which T-Mo says is dependent on the Sprint merger going through. (Was the point in unveiling TVision now simply to build consumer support for the merger?)
Also disappointing that they're retaining Layer3's high-end channel package, feature set and $100/mo pricing as the only option. It's fine to offer that but I was anticipating that they would go where the market is heading and also offer skinnier, flexible, cheaper bundles too, with a UI that could blend that content together with Netflix, Prime Video, etc. (They do say, at least, that those apps are coming soon to the TVision box.)
