To activate the flash sale offer, follow these steps:

Go to the Recharge or Special Offers section.
Look for the 400GB for ₹400 Flash Sale Plan.

This offer is part of BSNL’s customer acquisition and retention strategy, especially as it continues its battle with private telecom giants like Jio, Airtel, and Vi.
In recent years, BSNL has lagged behind competitors due to delayed 4G rollout and inconsistent service quality in some regions. However, the company is making a strategic comeback with:
Aggressive data pricing
Improved network coverage
4G and upcoming 5G trials
This flash sale is a step toward rebuilding its user base, particularly among budget-conscious customers in Tier 2 and Tier 3 cities, where BSNL still holds a strong presence.
Within hours of the offer’s launch, social media platforms like Twitter and Reddit saw users praising BSNL for finally delivering a competitive offer. Tech bloggers and digital influencers have started calling it:
“The cheapest high-data plan of 2025.”
Online recharge platforms also reported a surge in prepaid top-ups, with thousands of new activations and number port-in requests registered under BSNL within the first day.
Telecom analysts suggest this could be a short-term market disruptor, pushing competitors to rethink their prepaid data bundles.
Before you recharge, make sure to check the fine print:
This is a data-only pack; it does not include voice or SMS benefits.
Speed may be reduced after the full 400GB quota is consumed.
The offer is non-renewable and only valid for prepaid users.
No rollover of unused data beyond the 40-day validity period.
| Operator | Price | Data | Validity | Cost per GB |
|---|---|---|---|---|
| BSNL | ₹400 | 400GB | 40 Days | ₹1/GB |
| Jio | ₹666 | 126GB | 84 Days | ₹5.28/GB |
| Airtel | ₹599 | 144GB | 56 Days | ₹4.15/GB |
| Vi | ₹475 | 100GB | 28 Days | ₹4.75/GB |
BSNL clearly leads in terms of data volume and cost-efficiency, especially for users who prioritize data over voice calling.
The official BSNL Twitter account shared the details of the flash sale with the caption:
“BSNL brings a data storm! 400GB for ₹400 only. Limited time. Grab the offer before July 1. #BSNLFlashSale #DataDhamaka”
This tweet further confirms the legitimacy and urgency of the offer.

Students preparing for competitive exams and online coaching
BSNL’s 400GB data pack for ₹400 is undoubtedly one of the best prepaid data offers in India in 2025. While the plan doesn’t come with voice or SMS, its affordability and data generosity make it a must-grab for heavy internet users.
