The country's largest telecom operator, Bharti Airtel expects that the \u201cunsustainable\u201d tariff prices should start rising in next six months with industry having three more or less equal-sized players \u2014 Vodafone Idea, Bharti and Reliance Jio. \u201cThe pricing is unsustainable at the moment and the market is very competitive. I think that the pricing should start lifting in the next six months,\u201d Gopal Vittal, MD and CEO, Bharti Airtel (India & South Asia), said in an analyst call on Friday. Bharti said its capex for FY19 is around Rs 27,000 crore, most of which will be utilised for ramping up networks, but indicated that capex intensity would decline by FY20. Vittal said the company\u2019s focus is also on high paying customers in the prepaid and feature phone user segment, which will help in increasing revenues. On data consumption growth, he said that the usage rose on an average by 1.3GB per quarter. But per subscriber data usage is approaching its peak. However, it will take sometime to reach there, he added. \u201cOn voice consumption, I think it\u2019s getting close to the tipping point, but it\u2019s a surprise that people are talking a lot,\u201d he noted.
