Barclays Africa is examining takeover bids from prospective buyers for 9mobile. However, a deal may take a few months as it will involve restructuring 9mobile's debt after a default last year.
Airtel, India's largest telecoms operator, had expressed an interest to acquire the Nigerian firm as part of plans to consolidate its position in Africa's biggest telecoms market, but it declined to submit a financial bid before a January 16 deadline.
"Airtel is not interested in 9mobile because it sees little value in the company," one source said.
Another source said the Indian company did not have sufficient information to make an informed bid but added that privately-held Nigerian telecoms firm Globacom had submitted a financial bid.
No-one at Bharti Airtel in Nigeria or India was immediately available to comment.
Bharti Airtel, headed by billionaire Sunil Mittal, last year reported a 30.8 per cent fall in first-quarter net profit, blaming an adverse foreign exchange impact in Nigeria.
The central bank then intervened to stop creditors from putting it into receivership, leading to a change in its board and management, as well as its new company name.
The crisis forced parent company Etisalat to terminate its management agreement with the Nigerian business and surrender its 45 per cent stake to a trustee after the central bank intervention.
Since the debt problems came to light, 9mobile, the country's fourth-biggest operator, has rapidly lost subscribers. In October its users numbered 17.1 million, giving it a 12.2 percent market share, down from 20 million earlier last year, Nigerian telecoms regulator said.
South Africa's MTN, the market leader, has a 36.1 per cent share of the market in Nigeria.
