From time to time, your phone may lose connection with the T-Mobile network, similar to how a computer may lose connection to a wireless network. A device restart can help in resolving network issues like calling problems, poor signal, slow data speeds, and messaging issues.
Restarting your phone regularly can also help improve performance by closing all of the open background applications that may be slowing down performance.
Our recommendation: Restart your phone on a weekly basis. If you are having trouble with your phone, a restart (turning it off and then waiting at least 10 seconds to turn it back on) may help clear the issue.
