Yay, Christmas. Time for giving. T-Mobile is giving you 200 MB of free data per month. Check out the fine print, but it's a deal.
In order to get the 200 MB of free data per month, you need to activate a Mobile Internet account and register your tablet on our network. You don’t need to pay for an additional data plan. If you are a postpaid customer, you’ll need to have an On Demand data plan at minimum which is $0/mo if you are a voice customer (after $10 line credit).
You do not have to a purchase data pass in order to access your free data.
