Football game's are planned events, and the carriers plan capacity accordingly. I remember sms+cell phone going down on several music festivals with 20.000+ participants (especially when it ended at around midnight). Only some carriers supported those "sponteneous" gatherings in the middle of nowhere with mobile cell towers that would keep connectivity going - but low-cost carriers never did.
