Vodafone, the largest telecom operator in the megapolis with over 33 percent market share in terms of customers, said it will charge only 3G rates for the time being. The operator also said it will offer free upgrades to 4G and extra data for Vodafone Red customers for a month.

The company's Managing Director and Chief Executive Sunil Sood, however, admitted that faster adoption will take time as only 15 percent of its close to 9 million customers here have
4G-enabled handsets.

Sood refused to offer a revenue or customer base target for the new service, saying the targets are internal. He also said the high-speed 4G services will currently be available only in prominent business and residential corridors along the western and southern parts of the megapolis.

The complete coverage of the region, including eastern suburbs and New Mumbai licence areas, will be completed by the end of March. With the Mumbai launch, Vodafone, which has 4G bandwidth in five circles, completes the first phase of its 4G rollout. Sood said the second phase will begin from April.
