NEW DELHI : In a relief to Reliance Jio, Bharti Airtel and Vodafone Idea, the department of telecommunications (DoT) has extended the deadline for mobile operators who were to roll out their networks with a minimum stipulated capacity to 30 September to avoid stiff penalties amid the lockdown imposed to check the spread of coronavirus. “Due to (the) unforeseen situation in the wake of covid-19, the force majeure clause of the (telecom) licence is applied and relaxations are granted to licensees whose due date of registration for fulfilment of rollout obligation is between 25 March and 30 September," according to a circular issued by DoT.
