Hi there and thanks for coming to the Support site. Our T-Mobile ONE™ (Grandfathered) for Phones houses some pretty good info about the data on this plan. If you're primarily using Wi-Fi for your data, then the mobile data usage should go down.
I turned everything off and wi-fi is the only thing being used for data. I hope so. the only thing I left cellular data on is the phone. I hope it goes down. Thanks for advice.

@ abidelaw Your data will continue to go up but by having un-limited data means that you will NOT be charged for going over a certain amount of data. The price that you pay for T-mobile One plan includes using as much data as you want so dont worry that its showing the data going up ! Hope this helps !
