Idea Cellular today posted a loss of Rs 1,106.80 crore for the second quarter of the current fiscal, saying that the business was hit by pricing pressure and GST introduction in a "challenging" operating environment.
"The operating environment for Indian mobile operators remained challenging with unrelenting pressure on pricing, introduction of Goods and Services Tax at 18 per cent (compared to service tax at 15 per cent) and need for large investments to support the exploding data demand," Idea said in a statement.
