T-Mobile "4G" will gives me around 10-15mbps down and 3-4 up consistently around houston. T-Mobile's LTE (still spotty but very good considering it launched only a couple of weeks ago gives me 25-37 down and 9-14 up. So would say that it is a very good alternative if not better to verizon. In houston at least. Your speeds will vary depending on your location.
