Bharat Sanchar Nigam Limited (BSNL) has brought back the Unlimited Local & STD Calling Voucher but with a price revision that has made it somewhat more expensive now. Back in June 2013, BSNL withdrew (revised) its Unlimited STD Calling Vouchers but Local Unlimited Vouchers are still there.
Keeping in the mind the demand & needs of its customers & competition from private operators, BSNL has re-introduced Unlimited Local & STD On Net Calling Voucher.
