Motorola ic902 Deluxe
Single Band Phone
I rarely have any problems with my current
two band phone from Sprint
And if you switch between Sprint and Power Source coverage you'll see that with the single band Power Source you lose the gray (roaming) area.
And I hate to say it because I just switched to Sprint with a Power Source phone that the area your left with, with a Power Source is quite a bit smaller than some GSM (AT&T) carriers.
But did you buy the phone because it's what you want or the service.
