Why does my S5 keep showing "Unfortunately, T-Mobile has stopped

[Android Central Question]

What do you do to get rid of it?

I don’t know why it says that - though it may be that the S5 is showing signs of age - but if there is no pending update for the app, uninstall it.

TMobile app?

Welcome to Android Central! Go to Settings>Apps, select the T-Mobile app, then Storage, then Clear Cache/Clear Data, and then Force Stop. Now see if the problem persists.
