Apple is working with T-Mobile to fix network connectivity issues on T-Mobile iPhone 5, SE, 6 and 6 Plus models, CEO John Legere tweeted on Thursday.
Tweet: Apple is working to resolve the issue with iOS10 for TMobile customers. Don't download iOS10 if you currently use an iPhone 5SE, 6 or 6+. If you run into any connectivity issues, power off and back on to fix temporarily. Apple says a fix coming within 48 hrs
CNBC has reached out to Apple for more details. It comes on the heels of an iOS 10 glitch that froze some iPhones on Tuesday — it's unclear whether that issue, which Apple said was resolved, is related.
Neville Ray, T-Mobile's chief technology officer, tweeted that users that have already downloaded Apple's updated operating system should restart their phone each time they lose connection.
Tweet: If you have iPhone 5SE 6 or 6+ & already updated to iOS 10 and see issues, temp fix is to restart your phone every time you lose connection.
