Mumbai-based Tata Teleservices, a subsidiary of the Tata Group, deals in broadband, telecommunications and cloud services.

Notably, the shares of the company hit the 5 per cent upper circuit for several consecutive days in the recent past.

It is important to note that the rise in share prices of the company comes at a time when major Indian telecom operators have raised their prepaid tariffs by around 20 per cent.

In late November, telecom majors Vodafone Idea, Bharti Airtel and Reliance Jio raised their tariffs, which had already come into effect.
