Based on the nationwide voice and data test results combined with consumer research by Global Wireless Solutions(GWS), AT&T has the Best Network OneScore ranking, followed by Verizon in the second place with T-Mobile coming third and Sprint fourth.
GWS says its OneScore ranking combines engineering drive test data with consumer research. It takes into account both real-world wireless network performance as well as real consumer opinion on what they want from their network (from coverage to reliability, data speed, voice quality and video performance).
Verizon edges out AT&T for a win for fastest mobile internet upload tasks, like posting videos, photos, and other social media content. AT&T has the best video streaming quality and quickest loading time. AT&T scores top for voice retainability (i.e. lowest number of dropped calls), while T-Mobile takes the lead for best voice quality on calls made.Sprint is the only network to not finish first in any of the voice and data tests.
This is the most comprehensive program it has conducted in the U.S, claims GWS. Testing was done in all 50 states as well as Puerto Rico and the U.S. Virgin Islands. This was accomplished by driving nearly one million miles in 501 markets across the U.S. including major metropolitan areas, smaller urban cities as well as rural towns - representing a total population of over 300 million (94% of the U.S.).
