Mobile data sucks even in the densely populated northeast parts of the Amtrak system. Cell network congestion and dead spots where the railroad takes a path away from population centers and highways.
Yeah, and I'm not in the northeast, so for me, an Amtrak ride almost always means riding through long stretches of rural (and sometimes practically wilderness) areas. Mobile data connection goes in and out, very unreliable.
Not if it's going through remote, unpopulated areas (like the California Zephyr).
Admittedly, I felt this actually added to my enjoyment of the Zephyr ride -- total disconnection.
No, absolutely not. It constantly cuts out in the Northeast
