After hitting Chaukka with its STV 444, government owned telecom operator Bharat Sanchar Nigam Limited (BSNL) has hit a sixer. The telecom operator has launched ‘BSNL Sixer’ or 666 STV for its pan-India prepaid subscribers.
The new special tariff voucher (STV) BSNL Sixer 666 priced at Rs 666 offers truly unlimited voice call to any network and to anywhere in India. The combo STV will also offer 2GB of high-speed 3G data benefits every day. Post the daily data limit, speed will be reduced to 80kbps for rest of the day.
