    She said Cellular dont work anymore on her Iphone 5. Is there a way to revert back? Is this a known problem?

    Any fixes?

    Has she tried restarting? Taking the SIM out and putting it back in? Resetting some settings, like network settings? Perhaps restoring?

    Shes not home yet, but by restoring do you mean connect to itunes and use the last back up?

    Does that work? That reverts back to the old OS?

    I mean basically reinstalling the latest iOS to see if that would resolve it.

    It's highly unlikely that iOS 9.1 has anything to do with this issue. If there was a wide-ranging cellular connectivity issue with 9.1, a lot more people would be complaining. Most likely something just went wrong in the upgrade process - a settings file got corrupted or something to that effect. reverting to the older version is not the solution you're looking for.

    Doing the things C DM mentioned in his initial post, in the order he mentioned them (checking after each step) will almost certainly resolve the issue.

    I wouldn't use the last backup, as the corrupt file may be located in that backup. Try resetting network settings. - Settings->General->Reset->Reset Network Settings. If that doesn't work, I would restore it and set it up as new. A pain but will most likely solve the problem.

    Restore using iTunes then setup as a new phone. Test the cellular functions and if all is well restore the backup.

    I had a similar problem with my 6+ today after upgrading to 9.1, a couple restarts seems to have fixed it though.
