Chris Mills, BGR:

Apple announced the iPhone X, iPhone 8, and iPhone 8 Plus today. They’re all great phones in many ways, but they have one fatal flaw for T-Mobile and its customers: No support for T-Mobile’s new LTE network.

Right now, T-Mobile is in the early stages of rolling out a brand-new 600MHz network nationwide. The first sites are already online, and T-Mobile is expecting to cover a million square miles by the end of 2017. But the 600MHz network uses a brand-new LTE channel, Band 71, and very few devices support it yet. Sadly for T-Mobile, you can’t add the iPhone 8 or iPhone X to that list.

And:

The specs page for the iPhone X confirms that it supports all the usual North American LTE bands, but not Band 71. However you frame this, it’s a blow for T-Mobile. The iPhone X is widely expected to spark an upgrade “super-cycle” that will see people on the iPhone 6 and 6S spring for the upgrade, since they’re buying a phone that they expect to last for years. That phone — expected to last for at least two years — won’t be compatible with the LTE band that T-Mobile is expecting to be the backbone of its network going forwards.

Here’s the iPhone X specs page, look for yourself. Scroll down to the Cellular and Wireless section. No Band 71 mention.

Wondering if this support is something that can be rolled out in the future via an upgrade, or if it has to be baked in. If I was going to order an iPhone X and used T-Mobile, I would definitely want to know about this before I pressed the Buy button.

Any experts disagree with Chris’s take? Please do let me know.
