Telecom operators Bharti Airtel and Vodafone Idea said that they will hike tariffs from December 1, as a result of which mobile calls and data will cost more to their subscribers. In a statement Vodafone Idea said, 'To ensure that its customers continue to enjoy world class digital experiences, Vodafone Idea will suitably increase the prices of its tariffs effective December 1, 2019.' Hours later, Bharti Airtel also announced that it will raise mobile service rates from December.
