Former O2 UK Chief Executive Ronan Dunne has been appointed as Executive Vice President and Group President of US mobile operator Verizon Wireless.
Dunne, who starts his new role next month, left O2 UK following the collapse of its sale to CK Hutchison in May.
The Irishman will take charge of all aspects of Verizon Wireless’ operations, including its marketing, wireless, network operations, customer care and digital functions.
The company, which had 113.2 million retail customers at the end of the second quarter, competes with AT&T, Sprint and T-Mobile.
Dunne will report to John Stratton, Executive Vice President and President of Operations at parent company Verizon Communications.
Stratton said: “Ronan brings a wealth of expertise, as well as global wireless perspective and experience to Verizon Wireless.
“He has a proven record of performance in highly competitive environments.
“We look forward to his leadership as Verizon continues to invest in and evolve our wireless business to provide the best experience for our customers.”
Verizon Communications, headquartered in New York, has 162,700 employees, and generated nearly $132 billion in revenues in 2015 from mobile, fibre and entertainment services.
The company has made headlines in the past few weeks with two high-profile acquisitions.
It paid $4.8 billion for Yahoo! and $2.4 billion for Fleetmatics.
