MobileOne, Singapore's second biggest mobile phone firm, has unveiled the city-state's biggest stock market listing in three years.

The mobile operator is trying to raise up to 1bn Singapore dollars ($568m; �357m) by selling shares in 70% of the company in its stock market debut.

To take account of a difficult market for telecoms listings, the firm has pledged to pay a high dividend - up to 55% of earnings in the current year.

The shares have been priced at between 1.25 Singapore dollars and 1.50 Singapore dollars each.

"The valuation and the (dividend) yield are spot on," said Christopher Wong, a fund manager at Aberdeen Asset Management.

But brokers warned that the firm would have to work hard to woo investors during the next fortnight before the shares start trading.

"The appetite for investors to put new money into equity markets seems quite low at the moment," said Talib Dohadwala of First State Investments.
