Vodafone India, expects the Internet data use to drive the future growth in mobile telephony sector.

While at present, the company had a voice-data ratio of 80:20, this was rapidly changing with the advent of smartphones. “Data is the next stage of growth and the company is in the process of meeting this demand,” said R. Suresh Kumar, Business Head (Tamil Nadu), Vodafone.

To cater to the changing pattern in use of mobile phones, he told The Hindu here on Thursday that the firm had a person exclusively to explain the functioning of smartphones in all its 8,000-odd showrooms in the country, including 750 in Tamil Nadu.

Also, Vodafone had sent a bus to Tier-II and III cities in the State to give a demonstration on data use in mobile phones.

The company offered 2G network across Tamil Nadu and 3G in large cities with the speed ranging from 5 to 6 Mbps. Regarding mobile number portability, which was introduced in Tamil Nadu on January 20, 2011, he said that as of now, Vodafone had achieved a net customer positive addition of 5.6 lakh customers. The process of porting in and out of networks had settled down now with the process largely completed within the seven days mandated by Telecom Regulatory Authority of India.

As part of the social outreach programmes, Vodafone had tied up with the National Association of Blind to set up call centres operated completely by visually challenged persons.
