Bharat Sanchar Nigam Limited (BSNL) has launched an incredible Flash
Sale to celebrate the milestone of activating 90,000 4G towers across
India. For a limited period, BSNL is offering 400GB of high-speed 4G
data for just ₹400, with a validity of 40 days. This deal, priced at
an unbeatable ₹1 per GB, is a game-changer for budget-conscious
internet users in India. Whether you’re streaming, gaming, or working
from home, this offer ensures you stay connected without breaking the
bank. But hurry—this offer is valid only from June 28 to July 1, 2025

Why BSNL’s 400GB for ₹400 Offer Stands Out

In a competitive telecom market dominated by private players like
Reliance Jio, Airtel, and Vodafone Idea, BSNL is making waves with its
cost-effective plans. This flash sale is part of BSNL’s strategy to
attract new customers and reward loyal ones as it gears up for its
Quantum 5G (Q-5G) launch. With 90,000 4G towers already operational
and plans to expand to 1 lakh towers soon, BSNL is strengthening its
network to deliver reliable, high-speed connectivity across India.

Here’s what makes this offer a must-grab:

Massive Data: Get 400GB of high-speed 4G data, averaging 10GB per day
for 40 days—perfect for heavy internet users.
Affordable Pricing: At just ₹1 per GB, this is one of the most
cost-effective data plans in India in 2025.
Nationwide Coverage: BSNL’s 4G network is now live across India, with
improved coverage and capacity.

Note: This is a data-only recharge and does not include voice calls or
SMS benefits. Users must have an active base plan to avail of this
offer.

How to Avail BSNL’s 400GB for ₹400 Offer

Recharging with this limited-time deal is quick and easy. Follow these steps:

Visit the BSNL official website or use the BSNL Selfcare App.
Select the ₹400 data voucher under the flash sale section.
Ensure you have an active base plan, as this is a data-only recharge.
Complete the payment via UPI, debit/credit card, or other available methods.
Enjoy 400GB of high-speed 4G data for 40 days!

Alternatively, you can recharge through third-party platforms like
Paytm, PhonePe, or Google Pay, or visit a nearby BSNL store for
assistance.

BSNL’s Push for 4G and 5G Expansion

This flash sale comes as BSNL celebrates the deployment of 90,000 4G
towers, with plans to reach 1 lakh towers by mid-2025. The state-owned
telecom operator is also preparing for its Quantum 5G rollout, with
trials already underway in major cities like Delhi, Jaipur, Kolkata,
Hyderabad, and Chennai. BSNL’s Q-5G Fixed Wireless Access (FWA)
service, designed for enterprise customers, promises high-speed
internet without the need for a SIM card.

By offering such value-for-money plans, BSNL is positioning itself as
a strong competitor to private telecom giants, aiming to bridge the
digital divide in rural and urban India alike.
