The proceeds will be used to refiance its existing debt.
The company said in a statement that "its wholly-owned subsidiary Bharti Airtel International (Netherlands) BV has successfully priced CHF 350 million 3 per cent guaranteed senior notes due March 31, 2020."

"The notes received considerable investor interest, witnessing a strong and balanced demand across high quality institutional investors and Swiss private banks, highlighting the broad support base that the Bharti credit has attracted," the statement added.
"At CHF 350 million this is the largest ever bond offering by a domestic entity in the Swiss debt market," Deutsche Bank India head (financing) Randhir Singh told PTI in Mumbai.
Singh said the current issue received an overwhelming investor response and "we continue to see strong demand for quality Indian names in the global debt markets."
The company than re-opened the issue in January and raised 250 million euros.
In March 2013, the company had raised USD 1.5 billion in overseas debt in two tranches. Bharti Airtel had net debt of Rs 57,643 crore in December 2013.
"It is extremely heartening to have a third listing of our credit in just one year with yet another largest debut issuance from India. With this issuance, Bharti now has the largest debut USD, EURO and CHF denominated bond issuances by an Indian issuer ever," Bharti Airtel Group Treasurer Harjeet Kohli said in the statement.
The overseas fund raising had ebbed following the May 24 tapering talk by the US Fed, which spiked interest rates in Western markets. Since then there were only a few issues including HDFC Bank's USD 500 million in October and ICICI Bank's USD 750 million in December.
Shares of the company today settled 0.37 per cent higher at Rs 300.90 apiece on the BSE.
