BSNL, a government-owned telecommunication company, has presented its customers with a big surprise on the eve of Diwali. The company has introduced the "BSNLDiwali Bonanza 2025" offer, with the help of which customers can avail 4G service at the price of 1 rupee. This offer will remain in effect from October 15 to November 15, 2025. This translates to saying that for a month, customers can use BSNL's 4G speed and services nearly for free.

The firm states that this promotion is for first-time customers of BSNL who want to experience its network. It will be a free trial plan for the initial month.

The plan provides customers with 2GB of daily high-speed data, unlimited voice calls, and a free SIM card. The plan is for 30 days. After that, users can choose any regular BSNL prepaid or postpaid plan of their choice.

To avail this offer, customers will need to visit the nearest BSNL Customer Service Center or authorized retailer and complete the KYC process. They will then receive a Diwali Bonanza SIM card for ₹1, which can be activated immediately.

This offer will be available only during the Diwali period, i.e., until November 15, 2025. After this, the scheme will be discontinued. For more information and assistance, customers can contact the BSNL helpline (1800-180-1503) or the website bsnl.co.in.
