If you’re in the U.S., looking at a new iPhone 8 or iPhone X and you’re a T-Mobile customer, you may wonder if the new phone supports T-Mobile’s LTE Band 71, new 600 MHz spectrum the company is in the process of bringing online. The short answer is no. Apple’s new phones don’t support Band 71 and can’t be made to. You’ll have to wait until Apple’s next iPhone refresh to get that capability. The devil is in the details, so read on for more.
Some T-Mobile customers who upgraded their iPhones to iOS 10 this week have run into “No Carrier” problems following a botched Carrier Update setting. There’s a fix available that should help, and it’s easy to install.
Apple released iOS 10 earlier this week. T-Mobile customers also saw a Carrier Settings update when they installed the new operating system. Carrier Settings files give the iPhone key information about T-Mobile’s network.
This is where things went pear-shaped: Apparently something went wrong with the carrier settings updates for iPhone 6, 6 Plus and SE, according to Engadget. After upgrading, some of us noticed our phones were dropping offline. With the hinky carrier settings, once an iPhone loses a connection to T-Mobile’s network, nothing short of powering it down and turning it back on restores the cell service. That’s been my experience, and it’s maddening.
Late on Thursday, T-Mobile and Apple pushed another carrier update setting that should fix the problem. I haven’t experimented with it extensively to test it yet, but I do see that the update is live. Here’s how to apply it. Obviously this will only work once you’re connected to T-Mobile’s network or on a Wi-Fi connection, so if your phone is offline, make sure to restart it.
How to update your iPhone carrier settings
Tap the Home button.
The phone should automatically find the updated carrier settings automatically..
Once you’re done, you should see “Carrier” changed from 25.1 to 25.2.
