Reliance Jio and Bharti Airtel reported steady wireless customer gains in November, largely at the expense of Vodafone Idea (Vi) which continued to suffer heavy customer losses, unable to offset the impact of sharp hikes in base prepaid tariffs taken in late-July. Reliance Jio added 2.01 million wireless customers in November, taking its gross mobile user base to 428.61 million, while Bharti Airtel’s rose by 1.31 million to 355.29 million, according to latest subscriber data issued by the Telecom Regulatory Authority of India (Trai) on Tuesday.
