* Free incoming calls
* state-level number portability so you can switch carriers and hang on to the old number
* national level number portability
* compensation to callers for dropped calls -- an incentive for telecoms to uphold a certain level of service quality
* and now, a stern reply to FB's misleading campaign on free basics.
India as a result has very healthy competition in the telecom space, and the lowest rates in the world.
Kudos, TRAI.
