After Airtel and Hutch, cellular operator Idea, an Aditya Birla Group Company, has lowered ISD rates by 80 paise per minute.

Idea consumers will now have to pay Rs 6.40 per minute for calls to the US, Canada, Europe and Hong Kong instead of the earlier Rs 7.20 and Rs 9.19 for other destinations instead of Rs 9.99 earlier, a company statement said on Monday.

To rest of the world, consumers would have to pay Rs 49.20 per minute instead of the earlier Rs 50. Hutch and Bharti Airtel had reduced ISD rates from March 31 by 80 paise per minute, following Telecom Regulatory Authority of India's decision to reduce by 37 per cent the Access Deficit charge -- a levy paid by private operators to state-run Bharat Sanchar Nigam Limited for rolling out telecom services in rural areas.
