> I would think T-mobile would do the same with Sprint. You would think but consider this: Sprint is a MUCH larger network than MetroPCS with 4 or 5 different vendor regions and a mess of half-deployed hardware on their network. They still have Clearwire junk hanging unplugged in their towers. Then consider this, MetroPCS had mostly prepaid phone users... Sprint's got people paying down phones. In the old days the operator had a contract and the phone was subsidized, if they suddenly had to shut down towers in your area and you lost service.... the contract was void. With the exception of recent flagship models, there have always been Sprint variants due to weird spectrum allocations. MetroPCS just had more AWS spectrum for T-Mobile, so it was easy to move their customers in. T-Mobile's going to be on the hook with sunsetting Sprint's network for like 2-3 years post-merger. There's also a ton of legacy M2M stuff around (fire alarms and fleet tracking) that will need time to replace. My guess is that they move away from band 41 (2500mhz) TDD-LTE and go 5G with that since it's more useful than mmWave and won't be facing angry radar enthusiast pushback.
