5G speeds with only 1GB/m caps. $20/GB overages. You can watch a total of 2 minutes of 4K content a month. Hooray!
Guess what feeds the tower? Fiber! Go back to building that so the existing and future wireless networks can be augmented. Far more reliable, far more consistent. Seeing XLTE bomb to LTE to 3G is pleasing.
Also, do note that 5G hasn't been ratified into a standard yet.

Don't forget, true 5G requires Fiber to the tower. Where is Verizon going to find 1Gbps+ per sector?
More realistically, even in their ILEC areas the towers don't have Fiber from Verizon, and we probably won't see more than what the existing Gig-E circuits to the towers provide, anyways. Maybe 100Mbps at best for the more rural towers.
Just like anything else wireless, the more you put onto it sitting around, the slower it goes. I don't think 5G is going to solve that overhead problem any time soon.
