T-Mobile US promoted Jon Freier (pictured) to COO in a move to fill the void left by Srini Gopalan, who took over as CEO on 1 November.

Freier previously served as the operator’s consumer group president since 2021, but he has a long history with T-Mobile.

He started his career in the telecommunications industry in 1994 with Western Wireless, which became T-Mobile in 2021, according to a recent SEC filing announcing his promotion.

Gopalan mentioned Freier’s new role during an investor conference yesterday (9 December) as part of a plan to align “the organisation behind the strategy”. He assumed the role on 5 December.

A representative for T-Mobile told Mobile World Live the restructuring also included naming Mike Katz as the company’s chief business and product officer,  leading the company’s long-term strategy and planning. His prior role was president of marketing, strategy and product.

Gopalan took over as COO on 1 March after previously serving as a member of T-Mobile’s board of directors since 2022. He replaced Mike Sievert as CEO.

It’s worth noting Sievert served as COO prior to replacing former CEO John Legere in 2020 as part of a planned succession.
