BSNL Diwali Offer 2026 brings good news for prepaid customers looking for longer mobile recharge validity.
Bharat Sanchar Nigam Limited (BSNL) is offering 30 additional days of validity on its ₹2,799 annual recharge plan, increasing the total validity from 365 days to 395 days without any increase in the recharge price.
The festive offer also includes daily high-speed data, unlimited voice calling and free SMS benefits.
Customers who recharge with the eligible plan during the promotional period can enjoy the extended validity until the offer expires on November 30, 2026.
The additional validity means subscribers can use their mobile connections for an extra month without purchasing another recharge.
This could be useful for customers who prefer annual plans and want to avoid frequent recharges.
 BSNL Diwali Offer 2026: What Does the ₹2,799 Plan Offer?
Under the promotional offer, BSNL has added 30 extra days to its existing ₹2,799 annual prepaid plan.
The plan normally provides 365 days of validity. With the festive benefit, customers will receive a total validity of 395 days.
The main benefits include:
Recharge price: ₹2,799
Total validity: 395 days
Additional validity: 30 days
Daily high-speed data: 3GB
Voice calling: Unlimited
SMS: 100 messages per day
The additional validity also increases the total data allowance available throughout the plan period. With 3GB of daily data for 395 days, subscribers can receive up to 1,185GB of data during the validity period.
This is 90GB more than the data allowance available with the regular 365-day validity.
How Much Data and Calling Will Customers Get?
The ₹2,799 recharge plan provides 3GB of high-speed internet data every day. Customers can use this data for browsing, video streaming, social media, online communication and other internet activities.
After the daily high-speed data allowance is exhausted, internet speeds are reduced to 40Kbps, according to the reported plan details.
The recharge also includes unlimited voice calling to all networks, allowing subscribers to make calls without worrying about a separate calling balance, subject to the applicable fair-usage conditions.
In addition, customers receive 100 SMS messages every day. Over the complete 395-day validity period, this amounts to a total allowance of 39,500 SMS messages.
The combination of long validity, daily data, calling and messaging makes the plan suitable for customers who prefer managing their mobile expenses through a single annual recharge.
 BSNL Diwali Offer Last Date: November 30, 2026
The additional validity is part of BSNL’s limited-period Diwali promotional offer.
According to the company’s announcement, customers can take advantage of the 30-day additional validity benefit until November 30, 2026.
The offer is particularly relevant for existing BSNL subscribers planning their next annual recharge. New customers considering a switch to BSNL can also check the plan’s availability and applicable conditions.
Customers can explore recharge options through the BSNL Selfcare application, the company’s official website or authorised BSNL customer service channels.
Since promotional benefits are available for a limited period, subscribers should verify the offer before completing their recharge.
Is the BSNL ₹2,799 Annual Recharge Worth Considering?
The biggest attraction of the promotional plan is its extended validity. Instead of the usual 365 days, customers receive 395 days of service for the same ₹2,799 recharge amount.
Based on the promotional validity, the effective daily cost works out to approximately ₹7.09.
The additional 30 days also provide extra data and calling benefits without requiring another recharge during that period.
However, customers should consider their local BSNL network coverage and internet speeds before choosing the plan. Network performance can vary depending on the location, so checking connectivity in the area is important.
Overall, the Diwali offer provides existing and prospective BSNL customers with an opportunity to get additional validity and data benefits on an annual recharge.
Those interested in the offer should complete their recharge before November 30, 2026, after checking the applicable terms.
