Most of AT&T customers in Southern California are now able to make calls after technicians fixed the widespread outage that hit the service Saturday afternoon.

The glitch had started at around 3 p. m. on Saturday and carried throughout the evening, prompting customers to report the issue to the carrier. The technical glitch took out as many as 1,000 cell towers, leaving thousands of AT&T customers without service.

However, customers were able to send & receive data as well as text messages because the glitch had affected only voice services.

A spokesperson for the carrier said that outages were most probably caused by a mechanical issue with switching equipment which routes calls through the network.

The service was restored to most of the affected customers on Sunday. AT&T spokesperson Meredith Red confirmed, "We are pretty much all back online except for a handful of towers that will be up and running shortly."

As per a report published by KTLA, AT&T is mulling over plans to offer refunds/credit for the affected customers. However, it is still unclear how a person might qualify for some kind of refund/credit for the glitch.
