does anyone know of a provider who offers such a plan? i'll use att as an example, since that's what i have. my current plan is the SE regional plan tdma (no longer available). i can go anywhere in nc, sc, ga, fl, va, and east tn, and not pay roaming, no matter what the phone indicates. however, outside the SE, even on the att network, i'd be roaming. i would like to have national coverage. the problem is, if i were to switch to a national plan, i would lose quite a bit of coverage in my current SE region. this would be bad since most of my time is spent in the SE. i think the perfect plan would allow me to keep my current SE package, but allow national coverage as well when on the att network. that's probably asking for the moon, though, right?
