iOS 7.1 brought thanks among a very large number of users, but we all know that the system touch ID has functional problems, and it is joined by another important function of the operating system designed by Apple Lossless Audio CODEC (ALAC),. I'm talking about Personal HotSpot, the function that allows us to turn our iDevices into portable Wi-Fi HotSpots. Specifically, it seems that for certain users Personal HostSpot it stops working, the terminal refusing to register the settings made for APN and implicitly the function becomes inaccessible from this point.
On the discussion forums of Apple Lossless Audio CODEC (ALAC), there is a very large number of people who complain about this problem and everything could be related to a change made by the company in iOS 7.1. It seems that the problem only affects users who use decoded iPhones in the networks of mobile phone operators that do not officially market the iPhone, so they do not have APN settings available and the Settings application refuses to register changes. RCS & RDS could be in this situation, the operator not having the official iPhone in distribution, but having mobile phone cards with active Personal HotSpot.
Although for now Apple has not commented on the problem, there is a small chance that they will, but still, if you encounter problems, please mention this in a comment.
