Notably, a larg part of the rise was seen last week. In the week that ended on Friday (December 3), the telecom operator's share price rose over 30 per cent.

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

The Vodafone Idea's revised tariffs came into effect from November 25.

Reliance Jio and Bharti Airtel are the other two telecom operators which raised their prepaid tariffs in late November.
