In the US, I use my company's 800-number, and I'm all set.

Overseas, I use ATT Global Net and AOL as a back up. I hate AOL, but there are some locations where ATT Global Net doesn't have a service.

With ATT Global Net, I can use my Outlook and IE to check my e-mail and surf the net. With AOL, I still use IE to surf the net, but I have to log onto my company's intranet to download e-mail, as I can't get AOL to work with my Outlook.
