Idea Cellular has reportedly commenced shifting its 1.5 million prepaid customers to per-second billing system. The company has a total of 166 million subscribers, of which nearly 157 million are pre-paid customers. Idea Cellular?s decision to shift subscribers to the new system comes after Airtel made a similar move.

The operator has stated that the shift to the new billing system will occur over the next 30 days. Meanwhile, the new prepaid subscribers would automatically be served through the per-second billing system.

Meanwhile, the operator has stated that it will continue to invest in expanding its network of nearly 150,000 cell sites covering over 360,000 towns and villages with 2G and 3G networks, and roll out 4G LTE services in 10 key markets, starting calendar year 2016.
