Reliance Communications, India''s second-largest mobile phone carrier by subscribers, said it will restructure its wireless business over the next 30 days in a move to increase its competitiveness.

Reliance Comm said in a statement that it would discontinue with its current structure with three regional heads, and would name a new chief operating officer and create a "leaner and flatter" structure.

Reliance Communications' financial performance has been under pressure due to intense competition--which kept phone-call charges very low--and high interest costs on the debt it took last year to buy bandwidth and expand network. The revamp follows market leader Bharti Airtel Ltd.'s July announcement of merging mobile, satellite television, fixed-line and broadband businesses in a move that it said will improve efficiency and make the organization more agile.
