T-Mobile is pretty dense in the Louisville metro area, close to matching AT&T as far as macro sites go in most parts of town, both blow Verizon and Sprint out of the water here. This is also a pretty mature B71 & N71 area. When I previously had T-Mobile service back around 2014 they were horrendous here, but they did a ton a work between then and when I switched back in April of this year. What I hope they focus on here is rural coverage, as they are pretty even with what Sprint had and both lag far behind AT&T and Verizon in rural coverage here.
The Sprint Customers surely have a lot of value. Nobody would allow them to fade away. Something will be done.
The best option is for Shentel to continue somehow with this area. They built a killer network. Much much better than any other network in this area. Things will go downhill real fast if Shentel is out of the picture.
Actually, the Shentel network is so good that the Shentel sites need to be the backbone of the new network. Add t-mobile spectrum to the Shentel sites. Shentel is near perfect here and T-Mobile is very very poor. Shentel can fix that real quick.
I've not read the SEC filing lately, so I won't promise I'm 100% correct in case my memory is faulty. But because these terms are part of the existing affiliate agreement, I would assume that agreement continues to hold until it ends in 2029 (unless renegotiated sooner), including use of the branding and spectrum.
I know nothing about the billing system.
