T-Mobile Tells Customers Not to Install iOS 10 on iPhone 6, 6 Plus, and SE [Update: Fixed]

T-Mobile CEO John Legere says T-Mobile customers who own an iPhone 6, iPhone 6 Plus, or iPhone SE should not install Apple's iOS 10 update, released on Tuesday. According to Legere, iOS 10 is causing those three iPhone models to lose connection to the T-Mobile network.

Legere's comments come following customer complaints that started circulating following T-Mobile's latest carrier update, 25.1. It was initially believed the problem was the carrier update on T-Mobile's end, but Legere says that's not the case.

Apple is working to resolve the problem, but in the meantime, customers should avoid the update. T-Mobile has offered a fix for those who have already updated to iOS 10 and are experiencing connectivity issues -- restart. According to the company, the only way to resume connectivity is to restart the iPhone each time that it loses connection.

Apple is expected to have a fix ready in the next 24 to 48 hours.

Update: According to T-Mobile, Apple has fixed the issue for customers who were experiencing disconnects.


A T-Mobile Support document instructs users to go to Settings --> General --> About to install a new carrier update, 25.2.

Good thing they told users two days after the official release!

Seriously, do none of this come up in the GM testing at Apple or T-Mobile?

OOPS ... they did it again.

The Apple PR group will be along shortly to downplay this incident.
Wouldn't this be a T-Mo issue?

If the issue is a carrier update, that is provided by the carrier and added to the OS.

If it was an iOS 10 issue, then everyone would be having the problem, not just T-Mobile customers. They pushed a buggy carrier update along with iOS 10 on Tuesday and that's the real culprit here.
