AT&T Inc. should have most of its network problems behind it following Hurricane Gustav but is still experiencing some power outtages, said spokeswoman Sue Sperry.Sperry advised AT&T users to continue to text message and e-mail when possible to avoid strain on the network.”For a phone call, you’ve got to have two-way communication and an open line,” Sperry explained Sunday. “Texting doesn’t need that bandwith, and a text message just kind of gets in line and waits its turn to jump across the network.”—-Contact Jerit Roser at [email protected]
