I downloaded the NFL Mobile app in early September even after hearing that Verizon charged extra for it. My billing cycle ends on the 16 and I was able to view my bill yesterday expecting to see the additional charges but there wasn't one. My bill was the same as it was last month.
I had the app for about 1 1/2 weeks of that billing cycle so at the very least I would have thought it to be pro-rated for that time period. I'll be sure to report back after this months billing cycle.
In the terms and conditions is says something about agreeing to any and all costs but never specifically says that they charge you for use of the app, nor how much. Does anyone know what they supposedly charge for it?
They also mention something about promotional periods in which there aren't any charges so maybe I hit one of those. Not sure but so far I am happy with it.
