yesngo, that's the big difference between AT&T and Sprint. With the One-Rate plan from AT&T, even when you're in Roam, Extended Area, Analog, etc., there are no roam charges.

The only place I've had consistent minor problems is in the NJ Turnpike corridor, but once I get north of Exit 8 or 9, it works fine until I'm in NYC. As Rich said, it can be spotty in the city.
