Size of additional dowload required when installing titanfall for xbox one from disc?

We have purchased Titalfall for the XBOX ONE.  It also appears to be downloading data from the internet during the install from disc.  We are in a rural location and are limited to a cell based internet option either through a cell based hub modem or tethered to a cell phone.  Either option is rather expensive in terms of data.  Cell phone is a contracted 6 GB monthly limit and with additional charges above and beyond that 6 GB limit.  The hub option is 10 GB tiered pricing up to 30 GB and then gets very expensive with charges for each additional MB over and above the 30 GB. 

There is nothing that I can find in any of the documentation online or elsewhere that says how many GB of data is required to download for installation of titanfall even when it is being installed from disc.  This would be beneficial to know as data charges added for game intallation could add significant cost to any purchased game.  I would appreciate an idea as to what this number would be and would suggest it be made available for the many people that are in the same boat as us. 

Thanks
