Talking Activesync Device Management Policies - Data Monitoring

Hi Everyone

It has been some time since i have visited, but i can think of no better place to ask for help.

My company has provided all users with Android or IOS phones and each device is on a business plan through our local carrier (Telus).
Each account has a 2GB data limit, and overages are bloody expensive, thanks to Telus. There is no plan option to share a "pool" of data (ie 16 users @ 2GB = 32GB of shared data...) Instead, some of our power users go over and it costs the company $ while we have most users hovering around the 500MB/month.

I know that both Android and IOS have internal data monitoring tools, allowing for soft and hard limits for cellular data. I am wondering if there is a way to set and enforce these limits via an Exchange Activesync Policy. I have searched but found very little info on this.

I have found references to installing 3rd party software, but we are looking for a built in solution.

Thanks!!
