How can carrier limit hot spot connections I have encountered this question and in accepted answer there is information that doesn't click


  For instance, the iPhone 5 should theoretically be able to handle up to 14 connections, but both AT&amp;T and Verizon limits it to 5.


How can carrier limit hot spot connections? 

To clarify I own iPhone that uses sim card, and live in Europe.
It's baked into the iOS as a configurable number and the carriers submit carrier profiles that contain their preferred limits.
