SAO PAULO, Aug 4 (Reuters) - Brazilian mobile phone carrier TIM Participacoes TCSL3.SATSU.N expects higher revenue from prepaid mobile phone sales and rising market share to help boost operational margins in the coming quarters, executives told analysis on a conference call on Tuesday.

Earnings before interest, taxes, depreciation and amortization, a measure of cash flow and operational profitability known as EBITDA, rose 15.5 percent to 736 million reais in the second quarter from 637 million reais in the same period of 2008, the company said in a statement.

EBITDA as a proportion of sales, known as the EBITDA margin, should improve throughout the next few months, according to Luca Luciani, the TIM executive hosting the call.

The company reported on Monday a second-quarter net loss of 15.2 million reais ($8.3 million), compared with a loss of 66.3 million reais a year earlier. TIM, also known as TIM Brasil, is an affiliate of Telecom Italia TLIT.MI. (Reporting by Guillermo Parra-Bernal, editing by Gerald E. McCormick)
