Not being defensive, just want to know how you did it.
I dropped out of T-Mobile when we went three years with promises of service in Arkansas "soon" and the situation never improved. I'll mostly listen to the satellite radio while riding down the highway. Steaming music eats up a lot of my monthly 10GB over the cell phone and is quite spotty even in major metro areas in my experience.
I camp a lot of places, OK, TX, and AR state parks, COE parks - with no to limited cell service. Even if we have voice on AT&T - neither AT&T nor Verizon have data service for streaming.
The DW would be unhappy if I watched NASCAR while driving. ;)
