If you’re a T-Mobile customer in metro Atlanta and a large chunk of the Southeast, you might have had problems making cell phone calls Monday morning.

A notice posted on the carrier’s Web site at 8:48 a.m. read:

“Currently we have outages with the 2G and 3G networks in the following areas: Atlanta, Carolina, Miami, Orlando, Tampa. At this time there is no estimated time of resolution.”

Calls to T-Mobile headquarters in Washington state for more details went unanswered due to the time difference.
