Everything Everywhere has announced changes to its managament structure - the first tweaks under new chief executive Olaf Swantee's reign.
A team of 10 executives will report in to the CEO who was appointed to the role earlier in the year when Tom Alexander resigned.
Alexander had been CEO of Orange since 2008, before taking charge of the merger with T-Mobile in July 2010.
"The leadership team I'm announcing today draws from the existing talent within Everything Everywhere as well as bringing in some new faces with broad-ranging, international expertise," Swantee said.
"The structure of the team is function oriented with clear accountability so we can accelerate the execution of our key plans and priorities. I am committed to the established business goals and financial targets as well as to running a responsible and sustainable business."
The new lineup includes some new faces, but will see some senior employees leave the company too. Those departing include former deputy chief executive and chief financial officer Richard Moat and chief commercial officer Ian Pitcher.
"We would like to congratulate Olaf on his new appointment and wish him and his new management team all the best of success for the future. At the same time we would also like to thank Richard Moat for the role that he played as CFO and deputy CEO for Everything Everywhere," the company said in a statement.
"Richard was a highly valued member of the former management team and was instrumental in ensuring a rapid integration between Orange and T-Mobile, as well as reaching synergy savings ahead of time. We wish him all the best for the future."
