Once the data is consolidated, you can view wireless usage and costs by department, individual, or even service type (i.e., cellular, paging, etc.).

That's pretty damn impressive data usage for a cell phone. On 12/20, at 6:48 in the morning, I know for a fact my son was sleeping (we're in an RV right now), but AT&T claims 7MB of data use.

If you have limited cellular data on your cell phone plan, there's an easy way to check and manage your data usage on an iPhone.
