The company has taken a hit of Rs 13,500 crore due to network connection charges, or interconnect usage charges (IUC). Reliance Jio's decision to charge for voice calls comes after the TRAI floated a consultation paper to review if the regime timeline needs to be extended. In 2017, TRAI had slashed the IUC to 6 paise per minute. Earlier, IUC was 14 paise. TRAI had said that the regime would end by January 2020. Notably, Jio to Jio, landline calls, and calls made using WhatsApp or FaceTime and similar platforms will be free. Incoming calls from all the networks will also continue to be free for all the Reliance Jio users.
