The nation’s biggest wireless network operators have slowly but surely managed to reignite growth in their revenues from wireless services. And, according to a new Wall Street research report, that trend will expand next year.

At the beginning of 2018, many of the nation’s wireless network operators promised that their financial footing would improve as the months went by. For example, AT&T’s CFO John Stephens acknowledged in April that the operator’s wireless service revenues were essentially flat from the previous quarter, but he said the carrier is “confident that service revenues will improve throughout the year and still expect that we'll be positive for the full year on a comparable basis.”

AT&T wasn’t alone. Verizon, for example, notched a return to service revenue growth on a year-over-year basis in the second quarter of this year—for the first time since late 2014.

And in the third quarter, AT&T’s CFO crowed that “the tide has definitely turned in wireless,” noting that the carrier’s wireless service revenues rose 2.3% to $14 billion.
