....you can't drive out of range of the satellite.
Yes you can. Try parts of Old Keene Mill Road. Try the outer beltway, curving onto 95 South, next to that high wall. And other places.
I haven't lost Pandora, even in stretches of I-66 W where the cell signal is spotty. I assume it buffers a few minutes.
And there's always the good feeling that I don't have to call and go thru cancellation Hell. Hold times, talking with multiple people, arguing to drop the service. You know what I mean.
