I know how to set up the data alert and data stop for mobile data on my android but I can't figure out how to set it up on my daughter's iPhone. I have mine set up so it alerts me when I'm getting close to my data limit and then it will shut off mobile data when i hit the data limit. Can this be done on an iPhone?
iOS itself does not have the functionality you are looking for. There are plenty of 3rd party apps which can monitor the data usage and send alerts based on usage, but I don't believe that Apple will allow any app to turn off your cellular data other then their own settings app, and it only does that manually.
