TMobile was banking on the merger for 5G. They don't have enough spectrum for 5G plus Sprints capex was also part of the plan. If they are on their own, they will have to find a way to buy more which isn't available unless the can some how get their hands on B48 which VZW is buying. So their only option would be to force people onto 5G devices and use B71 and 66 or 2 for it. Sent from my SM-G965U1 using Tapatalk
