Mobile phone company- Karbonn is set to invest Rs 150 crore in product development, after sales service centres and marketing this year. “We are focusing more on product development and after sales service. Once we have a robust product road-map, we can think of manufacturing. We are going to go for disruptive marketing and increase market size for us. In all, we will spend Rs 150 crore in 2011-12,” said Karbonn Mobiles Executive Director Shashin Devsare. He also commented that Karbonn is going to set-up 1,000 ASC network in upcountry locations with at least 1 ASC in a radius of 150 kilometers and collection point in a radius of 60 km. “We have increased our investment in ASC by more than 15%. You cannot grow if you have pathetic after sales network,” Devsare added.
