I'm in a full time touring band. Our biggest bill after gas is our huge phone bill. At $15/gb our AT&T bill is often over $1000. There has to be a better solution. We prefer the big networks since a lot of our time is spent driving through the desert. But at this point we're desperate for relief from this huge bill. Unlimited would be best, but 100gb would probably do. Any mifi or satellite suggestions? This would be installed in a tour bus so it has to be mobile.
