Milligan’s current position as Three’s director of service operations and assurance has seen him work with the board to define Three’s operating strategy

Three has announced that Iain Milligan has taken on the role of chief network officer (CNO).

Milligan has been with Three since 2005, and his new role will see him be responsible for the performance of Three’s network and the rollout of 5G to ensure it continues to be the UK’s fastest 5G network.

As CNO, he will also continue Three’s £2 billion+ investment in its network including upgrades to the 4G network, and he will oversee the 3G switch off by the end of 2024.

Milligan will replace Carlo Melis who will return to Italy to become chief technology officer at Three’s sister company, Wind Tre.

Three UK and Ireland CTO David Hennessy said: “With seventeen years of experience at Three, Iain’s understanding of the company and its operations will drive the next stage of our network development as we continue the rollout of the UK’s fastest 5G network1 and build an even better 4G network.

“I want to thank Carlo for his work in developing Three’s network and I wish him the best of luck in his new role with our sister company, Wind Tre.”
