When I was viewing some of the reviews for this phone, they also performed some speed tests, so I decided to see how my phone would perform... it was OUTSTANDING!!!! I was pretty darn impressed, considering that my previous phone (Infuse 4G) only could handle about 3 to 4 kbps download, and about 1 kbps upload. Since I live in Chicago, the LTE coverage here is really good. If I was in an area without LTE, the results would probably be only half of what these were. I did two different tests at about 3 hours apart to see how consistent the results would be, and they were pretty consistent. I'm glad that I switched to this phone
