Telecom regulator TRAI has said that mobile operators will have to credit one rupee to a user’s account for a call drop from January 1, 2016. It said users would be compensated for no more than three dropped calls a day. TRAI or Telecom Regulatory Authority of India also said that the service providers would have to send SMSes to customers on the amount credited within four hours of a call drop. Postpaid customers would see the credit reflected in their next bill. A call drop means a voice call which after being successfully established, is interrupted before it is completed.
