Can anyone explain why my T-Mobile app is using over 1100MB of storage space?

This wasn't the case several months ago, but now it's the biggest data using app on the phone and I never use it. I can't root the damn thing at the moment because I don't have windows set up on this computer, so I just want to clear all that data out.

I would try going to settings > apps > and then find the T-Mobile app. From there select it and click "Clear Data" to clear it out.

I disabled it completely.
