So I have definitely went over the 2.5 gigs of high speed data in fact I have used almost 7 gigs of data in the past 5 days and I am still not throttled. Well I mean I am somewhat throttled but not nearly enough to be in any way upset. The first couple days after I activated my sim card with the 45$/ month plan I went LTE crazy downloading movies, watching YouTube/Netflix and even tethering my ps3 to play COD. I used 4 gigs in 2 days. In which the whole time I received lte speeds of 20mb/s or better. After day 2 they did throttle me but I'm still receiving max speeds of 14mb/s and consistent downloading of data at a rate between 1.5 and 4 mb/s... So far I am very impressed...
P.S. My buddy has official AT&T service with an iPhone 5 and receives upwards of 50 mb/s at all times sitting in my living room. Lol. And I can also report that there was a lte tower activated on march 22,2014 in darke county Ohio.
