I have seen 68mbps from my Verizon Samsung Galaxy Note II. However, Att does have the fastest 4GLTE(18.6 vs 14.3 on Verizon) , but Verizon network is much larger. Verizon also offers unlimited unthrottled 4GLTE. Att throttles.
" AT&T outshines Verizon in 4G LTE speed tests
by Lance Whitney March 12, 2013
AT&T may not have the largest 4G LTE network but it has the fastest, at least according to new data from Root Metrics.
Among the top four U.S. mobile carriers measured by Root Metrics, AT&T took the top spot with an average LTE-only download speed of 18.6 megabits per second and an average upload speed of 9Mbps. Its maximum download speed averaged 57.7Mbps, while its fastest upload speed averaged 19.6Mbps.
Root's researchers were able to connect to AT&T's LTE network 81.7 percent of the time, a rate second only to Verizon Wireless.
Verizon itself took second place in the speed tests. The carrier offered an average LTE download speed of 14.3Mbps and an average upload speed of 8.5Mbps. Its maximum speeds averaged 49.3Mbps on the downstream and 19.7Mbps on the upstream. And its 93.2 percent reliability rate was the best among the bunch.
Verizon also was No. 1 for LTE coverage. Of the 77 LTE markets included in Root's study, Verizon's LTE network was available in all of them. In contrast, AT&T's LTE network was found in only 47 of the 77 cities."
