Idea said it was able to contain, on sequential basis, voice rate decline by 0.2 paisa per minute to 32.7 paise per minute for second quarter but the blended mobile data average realisation per MB fell by 1.2 paisa to 23.4 paise per MB in the reported quarter.
The non-voice revenue contribution improved to 27.9 per cent this quarter against 21.1 per cent a year ago, it added.
The net mobile data customer base has risen to 41.3 million. The data average revenue per user (ARPU) of 3G customer stood at Rs 202.
During the quarter under review, Idea spent Rs 1,726.6 crore on capital expenditure adding 9,947 sites.
It said industry revenue growth is trending low due to reduction in mobile incoming IUC charges settlement rate from 20 paise to 14 paise per minute from March 1, reduction in national call charges and SMS rate between 20-75 per cent effective from May 1 and pressure on mobile data realised rate due to intense competition.
