So, as you've surely heard by now, the new Apple iPhone X was revealed to the world yesterday as the biggest revolution since the original iPhone. They did away with the home button, introduced animated animal emojis, and introduced the notch. If you were excited to use the new iPhone with T-Mobile, though, you may be in for a bit of a disappointment.
T-Mobile's new LTE network utilizes a new channel, Band 71, and understandably there aren't too many devices that support it yet because T-Mobile is the only major carrier in the United States who's using it. That makes sense, but considering that the iPhone X was just announced and how big of a deal it's going to be, you'd think the team at T-Mobile would have lobbied Apple to include it on the spec sheet.
It might not sound like a huge deal right now, but the Apple iPhone X is going to sit on store shelves for at least a couple of years and the lack of Band 71 support is going to hurt it more and more as time goes on. The lower frequency network allows for longer travel and better penetration through buildings, leading to better and more reliable coverage. This could mean that some T-Mobile customers could even jump ship to Verizon to get the 700MHz spectrum for their new iPhone. This is also true for the iPhone 8 and iPhone 8 Plus.
If you want to stick with T-Mobile for that Band 71 action, your only option at the moment is the LG V30. While it's true that the Galaxy Note8 doesn't have Band 71 support, we can be pretty confident that next spring's Galaxy S9 will.
