Get Cellular Provider / Carrier

I can get a lot of information about the device (model, os, etc…) but I’m having trouble finding a way to grab the carrier information. I know it’s possible on the devices, but I can’t find the Unity way to do it - anybody?

The Unity way to do it is to write a plugin that can all into the native OS to get this information. On an iOS device that might just mean writing some Objective-c.
