Apple’s iOS 11 is the newest latest major release of the operating system that powers the iPhone and iPad, and it’s a significant change. Here are a few tips to make that upgrade and transition as smooth as possible – what to do before you upgrade, when you upgrade, and what to do if things go wrong after the upgrade.
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
Once you’re done, you should see “Carrier” changed from 25.1 to 25.2.
