Given the upcoming transition to 5G, which cell carrier is likely to be most futureproof for current iPhones, especially since Apple won’t be making the jump to 5G anytime soon? I’m currently on Verizon, but since they’re shutting down CDMA sometime in 2019, I wonder how seamless that will actually be? I’m pretty sure it won’t be an issue with LTE, but thinking of moving to T-Mobile as they seem poised to amp up their network with the Sprint merger. Any thoughts on this would be helpful.
