Trai is considering issuing a showcause notice to Vodafone Idea over the priority plan issue as the telecom regulator is not satisfied with the response given by the company on the matter so far, according to a source.

Airtel — which has stopped onboarding new customers on its platinum offering after an earlier Trai directive — may not be served a showcause notice.

A regulatory source said that Vodafone Idea has not been able to satisfactorily respond to many of the issues raised by Trai, including two major concerns on how the company will ensure priority services and speeds to select customers who opt for the premium offering, and how the priority plan will not adversely impact services and experience of non-premium users.

The source said the company has not been able to offer clear answers to the issues raised by the regulator.
