Backlash over Reliance Jio's decision to charge voice calls
Reliance Jo's offer of one-time, 30-minute free talk time on top-up voucher may not be enough to pacify customers incensed by the 6-paise-per-minute charge on inter network voice calls.Jio.Com

A few days back, Reliance Jio said that it would charge its customers 6 paise per minute for calls made to other networks till the telecom sector regulator TRAI moves to a zero termination-charge regime.

The step is seen as Jio's response to account for the termination charges it pays its rivals Bharti Airtel and Vodafone Idea. Lately, Jio and other telcos have been engaged in a war over interconnect usage charges (IUC).
