Telecom service provider Bharti Airtel, whose network suffered functional problems in Mumbai and some other places in western Maharashtra Tuesday, said it has restored the mobile voice, BlackBerry and SMS services.
Customers faced service outage since Tuesday morning. They were not able to make or receive calls and send messages.
"Mobile voice, BlackBerry and SMS services have largely been restored and are stabilizing. We are working towards restoring 2G and 3G data services later tonight," the company said in a statement.
"However, for the enterprise services like leased lines and internet services, the restoration work is in progress and these services are likely to be restored in the next 24 hours," it added.
The company confirmed reports that the outage was caused by a fire in the network's central point of presence in Malad, a Mumbai suburb.
