The Telecom Regulatory Authority of India, or Trai, will soon decide on the vexed question of the interconnect user charge, or IUC. The IUC is a payment, per minute of a completed call, from the network where the call originates to the network where the call terminates. The essential idea behind the IUC is that it compensates the company where the call terminates for its investment in last-mile connectivity, since part of the call will naturally be carried over the infrastructure that the call receiver’s chosen mobile company has installed. Currently, the IUC is 14 paise a minute; the question is whether, and if so by how much, this should be reduced. Many incumbent companies, including the largest — Airtel, Idea, and Vodafone — have in fact asked for the IUC to be increased, perhaps doubled. Meanwhile, the cash-rich new entrant Reliance Jio, which has shaken up the industry through its various user subsidies, has demanded that the IUC be halved.
