My mom had Cingular about 5 years ago. At that time she could not get voice mail by pressing the voicemail button on her phone when she was outside her billing address state. To get voicemail she had to dial a separate number (don't recall if it was local or 800)., enter her password, and then get messages. I've been w/ Sprint for 7 years and voicemail works the same anywhere in the country. So my question is: is AT&T's email still the same awkward system or is it like Sprints where it just works where ever you go in the US?
