The guidelines issued by TRAI applicable from June 1,2013 are given below:
1. SMS termination charge of 2 paise applicable across networks.
2. Currently, only Promotional SMS were charged IUC (Interconnecting Usage Charges) cost of 5.5 paise. Now after the implementation of new regulation & guidelines, Transactional, Promotional as well as Normal messages will be charged a I.U.C (Interconnecting Usage Charges) cost of 5.5 paise.
The carrier on which the SMS or call originated to the carrier whose subscriber it is delivered pays termination charge. Without any IUC (Interconnecting Usage Charges) cost, the carrier on whose network the SMS terminated would get nothing and yet is expected to deliver the message using its resources. Overall, the SMS termination amount now will be ~7 paise. These are the messaging Guidelines for Bulk SMS
