unfortunately t mobile has stopped

So idk if this will help anyone. But I noticed that the tmobile app that was in my apps in the play store was different than the one continously generating the error. So I went to the app store, and under my apps searched tmobile, it showed a tmobile app with a PINK icon, I clicked on that and while it was installed, it was not enabled. So I enabled it.Then when the pop up occurred again, I clicked on app info instead of close app. Which brought me to the older tmobile app with a white icon, i clicked the 3 dots in the top right,  and then clicked uninstall updates. So far everything is running smoothly and no more pop ups are popping. Fingers crossed!
