$5 a day per device to a max of 50 and you just use your normal data limits. Works great for us, we share 10g and basically used more data than normal but still won't come close to our monthly cap. Love it, I've been watching hockey most of the afternoon, although I had to switch to my phone for some location based reason. Julie watched Netflix for hours on the drive down, except in places with expectedly shit cell coverage like North Dakota and Nebraska.
I think TSN is kinda shitty with their apps, I was able to watch everything in the US on wifi even stuff I'm sure they should have blocked like NFL
AT&T middle of nowhere, 10 down 1 up on LTE
