T-Mobile has some advice for those who can't make calls: restart your phone.
A nationwide system outage prevented customers of the mobile carrier from making calls and using their data plans overnight.
The company acknowledged on Twitter they were having some issues as frustrated mobile customers aired their complaints when everything came to a screeching halt.
T-Mobile said the issue has since been resolved, and all you have to do is restart your phone.
If it doesn't work, you can try dialing 611 from your device or calling 877-453-1304 from another phone.
