Subscribers in Singapore will be able to call India at 10.5 Singapore cents per minute on a toll-free access number.
As part of its launch offer, Airtel is also giving 20 minutes of free talk time trial.
''Customers in the Singapore market, which is today dominated by physical calling cards, are looking for greater transparency in charges and ease of usage,'' Bharti Airtel President (Enterprise Services) David Nishball said.
