Indonesia’s mobile phone firm PT Telekomunikasi Selular (Telkomsel) intends to raise up to $318 million by selling bonds or medium-term notes. Telkomsel, which is 35 per cent owned by Singapore Telecommunications (SingTel), has pegged this year’s capital spending at up to $1.7 billion. Of this, the company is planning to internally fund half the amount and seek financing for the rest.
