We carry mobile hotspots (Mifi) devices for Verizon (prepaid), AT&T and T-Mobile and most places all three work, but there are definitely places where only one works. Our experience all over the country is that AT&T is the most likely to have usable service when the others do not, followed by Verizon and with T-Mobile being in last place. But we find that T-Mobile is often our best choice for speed and does work in most places. Our phones are postpaid Verizon and we put them on Wifi when Verizon does not have usable service.
Sounds like you've noticed that AT&T is usually the one that works when Verizon and T-Mobile don't. But hey, T-Mobile kicks ass when it comes to speed and it works in most places. So even though AT&T is the most reliable in those tricky spots, T-Mobile wins the race in terms of speed and overall performance.
You've got the right idea by using your postpaid Verizon phones on Wi-Fi when their service sucks. That way, you can enjoy the perks of T-Mobile's speedy connection without compromising on coverage.
