There are 4 phones and 1 iPad. We were sharing 22 gigs, and were doing great, until upgrade to unlimited just for the peace of mind of not going over the data limit, not to overuse it. But this has been terrible. Did a speedtest with my coworkers and wife's cell phone under AT&T and they are quite faster here at Orlando, FL.
Used to be an AT&T customer, and that was the reason I switched to Verizon, but now it is unbearable. Will give them one more chance, to see how it does after downgrading back to 20 gigs.
