I think the problem is that none of the local cell companies support any of the short-dial codes (#228, #777...) any time I dial these numbers (even manually) I get a message from Chat Mobility (the local cell company) saying, "Your call cannot be completed as dialed. This is Chat Mobility... blah blah blah..."

I'll try it next time I'm in an Alltel calling area and do a #228 update and activation; we'll see if that helps. Thanks to everyone whose posted possible solutions. =)
