BSNL Diwali Bonanza Offer
The BSNL Diwali Bonanza 2025 aims to let new users experience the company’s enhanced 4G network for just Re 1 for an entire month. The offer covers unlimited voice calling across all networks and 2GB of high-speed data per day. After hitting the daily usage cap, the user will still be able to continue using the internet at lowered speed.
The plan is meant to encourage new users to use BSNL’s upgraded 4G network as a trial before committing to either a longer-term prepaid or postpaid plan.

The promotional offer will be available from October 15 to November 15, 2025. There will be a 30-day complimentary access to BSNL’s 4G services for new customers who activate a new BSNL SIM during the promotional period. After the complimentary period ends, the customer can switch to any one of BSNL’s prepaid or postpaid plans, based on their choice.
