Bharat Sanchar Nigam Limited (BSNL) has rolled out a new offer, called Bonanza, which provides all new and existing users up to four months of extended validity. To get this extended validity, a user has to choose a broadband single plan for a longer period.

As per industry sources, BSNL will provide an additional three months of service if the customer opts for a 24 months fixed subscription, which effectively means 27 months of service. Likewise, a subscriber opting for a single plan for 36 months will get additional four months of service at no extra cost.

BSNL is already offering one month of free service if customer chooses a single plan for 12 months
