These wireless networks have fewest call issues, JD Power study finds

Verizon has ranked No. 1 for having the fewest call issues for 13 consecutive years

Verizon Wireless customers reported the fewest call issues in 2020, followed by AT&T, T-Mobile and Sprint, J.D. Power's 2021 Wireless Network Quality Study found.

Verizon has ranked No. 1 for having the fewest call issues per 100 mobile interactions and across six U.S. regions for 13 consecutive years, according to the J.D. Power study released Tuesday.

AT&T ranked No. 2, and T-Mobile ranked No. 3 in most regions, followed by Sprint, which merged with T-Mobile in April of last year. The study is based on responses from more than 33,000 wireless customers throughout the U.S. from July to December 2020.

"Mobile phones have evolved from their roots as a voice-only product to provide incredible network-connected, app-driven experiences,” Ian Greenblatt, managing director at J.D. Power, said in a statement Tuesday.

Greenblatt added that "while there is room for an identifiable boost in call quality satisfaction, the hardware of modern phones are not the culprit of call quality problems," and "ensuring the prioritization of call quality within network traffic will improve their voice experiences, and with it, overall satisfaction."
