    Welcome to Android Central! If it was only losing service intermittently, I'd suggest trying a new SIM card from your carrier, but the fact that it's also shutting down on its own makes me wonder about some hardware problem. Does this happen in Safe Mode? https://support.t-mobile.com/docs/DOC-11724
