T-Mobile’s network stayed solid from Denver up through Fort Collins; its
coverage has improved a lot in the past year or two. If you regularly go to
Wyoming, though, you need Verizon. All the other carriers dropped to 3G or
worse on our trip through Wyoming. We also hit a deer.
DETROIT: VERIZON
Detroit was almost a three-way tie between AT&T, T-Mobile, and Verizon. But
Verizon just nabs it, according to our testing methodology. Verizon had by far
the highest peak LTE download speeds and the best average upload speeds,
although AT&T beat it on average download speeds.
Verizon’s gigantic 150Mbps peak was a bit of a fluke in a city that, all around,
was not one of our fastest. But the carrier didn’t hit any noticeable slow spots,
while speeds on T-Mobile and Sprint varied sharply from test site to test site.
HOUSTON: T-MOBILE
Houston delivered fast speeds on all four major carriers, with everyone peaking
over 100Mbps. It was also Sprint’s fastest city and one of a very few cities where
Sprint had the fastest average download speeds.
T-Mobile won by pairing fast download speeds with equally excellent upload
speeds, for a network that’s enjoyable for both content creators and consumers.
T-Mobile’s network was also more consistent than Sprint’s, offering fewer ups
and downs as we traveled around the city.
