Up to $3.5 billion in Apl shares were traded on New York stock exchanges in the morning.
The stock rose as much as 13.5 per cent in the session.
The Apl is a mobile operator in India, which launched in the US in 2011.
Apl will now go on sale in India later this year, and will be sold through a consortium of telcos.
Aipl has raised an additional $2 billion from its investors, including SoftBank Group Corp. and Bharti Airtel Ltd.
APL has raised $10.4 billion from investors.
The telecoms operator, which was once a subsidiary of Reliance Industries Limited, had been one of the biggest winners of the government’s $3 trillion mobile network investment programme.
The investment has been the subject of fierce opposition from telcos and activists in India.
