T-Mobile has come out on top in J.D. Power’s business wireless ranks once again.

J.D. Power today announced the results of its 2019 U.S. Business Wireless Satisfaction Study, and T-Mobile has come out on top for the third straight year. The study measures satisfaction across six factors: performance and reliability, customer service, sales representative and account executive, billing, cost of service, and offerings and promotion. It’s based on responses from 2,797 business decision-makers that were fielded between July-August 2019.

T-Mo actually came out on top in all three categories measured by J.D. Power. The Large Enterprise segment includes businesses with 500 or more employees, and T-Mobile 868 points out of 1,000 here while AT&T got 849, Verizon put up 836, and Sprint finshed with 808.

The Small/Medium Business category includes businesses with 20-499 employees, and T-Mobile got a score of 844 here while Sprint got 830, Verizon scored 819, and AT&T got 810 points. Finally, the Very Small Business segment includes businesses with 1-19 employees, and here T-Mobile scored 843 points, Verizon got 807 points, AT&T earned 762 points, and Sprint rounded things out with 759 points.

Here’s what T-Mobile CEO John Legere had to say about today’s news:

“Four years ago, we took a leap of faith and made a bet that business customers want simplicity, transparency and a fair value. Three straight J.D. Power wins later, and it’s clear that we were right! Business customers continue to shake up the status quo with us, and they are happy about it! When you put customers first — it shows! With our incredible network performance, reliability and award-winning customer care, we won’t stop making our customers the most satisfied in wireless.”
