India’s Reliance Jio Infocomm plans to market its long-anticipated 4G service through more than 1,000 ‘Jio Centres’ and will offer Jio-branded devices under its parent company’s retail unit, Reliance Digital.

The operator, which is owned by Reliance Industries, is investing INR1 trillion ($15.7 billion) to launch 4G service across India by December, following an “extensive beta launch”. It has already invested three-quarters of that amount.

The operator plans to market devices via open-market channels as well as offer Jio-branded handsets, covering entry-level to premium 4G smartphones, the Economic Times said. In addition to the Jio Centres, the company will have 500,000 connectivity outlets and one million recharge outlets when it launches.

The company is partnering with a number of handset vendors to produce 8-10 million 4G devices a month, the bulk of which will be priced at under INR4,000 ($63).

Mukesh Ambani, chairman and MD of Reliance Industries, said it is open to acquisitions and spectrum sharing and trading to boost its spectrum holdings.

The government is expected to soon issue new rules for spectrum sharing and trading, which many analysts say will kick off a new round of M&A activity in India.
