Users on Airtel network across the commercial capital of the country, both on the western and central suburbs, complained of disruption in services. Signals were not available from 10 in the morning, Airtel subscribers said.
The fire broke out at the Peninsula Chambers in Lower Parel and resulted in failure of equipment. This has affected users in certain areas in the city, a company spokesperson said.
"There has been a fire at Peninsula Chambers, Lower Parel, Mumbai due to a short circuit in the common power cables, belonging to the power supplier, in the facility area of the building. This has resulted in a temporary disruption in power supply, which has impacted our network services in some areas of Mumbai," Airtel said in a statement.
The company said it was confident of "restoring normalcy soon".
Bharti Airtel has a subscriber base of around 2.5 million in Mumbai of the total 69.4 million in the country.
