why have I lost all data when using T-Mobile network??

Worked fine yesterday. Woke up today and worked fine while on Wi-Fi. When I left the house, nothing. I live near Detroit. Called customer support and they tried a bunch of stuff and nothing. I have full bars, can make phone calls, but no data at all.

Ensure your APN settings are properly set. If so then ensure there are no outages.
