My gripe is that others around me on different networks have no problem at all.
I get that a mass influx to a mast hold things up..I actually train such information as a part of my job.
What irks me is that it's NOT the same on other networks.
When I say bad, I mean that after the game when I'm scanning twitter etc. Even with a 4G signal I can barely get 1 bar and thus barely any refresh until I'm well clear of the stadium
Frankly I expect better
