There are two big reasons why the launch of the three latest iPhone models, the iPhone Xs, Xs Max and XR, are likely to benefit T-Mobile: spectrum and compatibility.
The latest iPhones include eSIM tech, which makes it compatible with any carrier. And for T-Mobile which is invested in a strategy of convincing users to drop their existing network in favor T-Mobile, that’s a big deal.
There’s also the matter of the 600 MHz spectrum, which The Street points out T-Mobile acquired last year for $8 billion, that also happens to be compatible with the new generation of iPhones. Now T-Mobile can dangle the latest Apple phones as an addition incentive to attract customers to their network.
