INTRO: Jio's ₹36,000 Cr IPO and the "Tech Company" Claim
Recently, Jio filed its DRHP for a ₹36,000 Cr IPO. This could be the biggest IPO in Indian history.
While reading Jio's DRHP, we found one sentence repeated again and again:
That means Jio is positioning itself not as a telecom company, but as a technology company.
The company reported 52.44 Crore subscribers. 60% of India’s wireless data traffic runs on its network and it has filed 6,817 patents.
Jio is now also betting big on Data Centers and AI. And it has announced plans to build its own Low Earth Orbit Satellite Constellation to directly compete with Elon Musk’s Starlink.
On the other side, Airtel, India’s second-largest telecom player, is also expanding aggressively. Airtel has made multiple announcements in Data Centers, Financial Services, and Cloud.
For FY26, Airtel launched its own Telco-Grade Cloud Service. Over the next few years, the company wants to take its Data Center capacity to 1 Gigawatt.
Overall, the sector is seeing massive activity. Players are now competing on 3 fronts:
- Telecom Data Plans
- Digital Products - Cloud Gaming, Cloud Computing, Smart Home
- Satellite Communications
In today’s article, we will break down India’s telecom sector across these 3 fronts:
- Part 1: Business Performance, Data Plans & Growth Strategies
- Part 2: How companies are diversifying into Digital Products & VAS
- Part 3: Satellite Communication plans of all players + International players
Basically, Airtel vs Jio on 3 fronts.
PART 1: THE CORE BUSINESS - Data Plans, ARPU & Network Economics
How The Duopoly Was Formed
Today, India’s telecom sector is almost a duopoly. Airtel and Jio together have 70%+ subscribers and 76% Revenue Market Share.
But it wasn’t always like this. Until early 2010, India had ~15 telecom operators. In 2016, Reliance Jio entered and dropped data prices by over 90%. That completely changed the landscape.
Data as of Feb 2026:
- India has 132 Crore Telephone Subscribers and 113 Crore Internet Subscribers.
- Before Jio, an average Indian used 27GB/month. Today it’s 20GB+ per month. That’s a 74x increase.
- Globally, 1GB costs $8-$10. In India, it’s just $0.24 cents. We are one of the cheapest data markets in the world.
Now only 4 major players remain: Jio, Airtel, Vodafone Idea, and BSNL. And Jio + Airtel dominate.
Spectrum, Towers & Capex
To operate, telecom companies must buy Radio Spectrum through auctions. So far, there have been 9 auctions and companies have invested ₹5.6 Lakh Crore.
For towers, there are 2 big companies: Indus Towers (Airtel subsidiary with 2.5 Lakh+ towers) and Summit Digital (owned by Brookfield, with 1.75 Lakh towers).
| Telecom Player | FY26 Revenue | Subscribers | ARPU (Average Revenue Per User) |
|---|---|---|---|
| Jio | ₹1.46 Lakh Crore | 52.44 Crore | ₹241 |
| Airtel | ₹2.11 Lakh Crore | 48.24 Crore | ₹257 (Highest) |
| Vodafone Idea | ~₹45,000 Crore | 19.2 Crore | - |
| BSNL | ~₹21,000 Crore | 9.2 Crore | - |
Biggest costs: 20-25% Network Operating Cost + 30-40% goes to Network Charges, Access Charges & License Fees. After operating costs, companies are left with 40-60% EBITDA margins.
ARPU War: Airtel’s Premium vs Jio’s Volume Play
The playbooks are different: Airtel is focused on premiumization, while Jio is focused on volume. That’s why Jio has more subscribers, but Airtel has higher ARPU.
BSNL’s ARPU grew 42% in FY26, but that’s because its active subscriber base dropped from 63% to 57%. So the average went up on a smaller base.
Tariff Hikes & 5G Monetization
To grow revenue, companies are doing 2 things:
- Tariff Hikes: Because costs can’t be optimized much, companies keep raising tariffs. As an oligopoly, if one raises, others follow. Industry estimates suggest another 15% tariff hike in Q2-Q3 of FY27.
- 5G Penetration: In the last 3 years, Airtel and Jio upgraded 5 Lakh+ transceiver stations to 5G. 46% of Airtel’s base and 51% of Jio’s base are now 5G users. Vodafone Idea started 5G in Q2 FY26. BSNL is still upgrading 4G sites.
But here’s the catch: 5G is still being offered at 4G prices to get users on board. Airtel management even said that 5G is currently a headwind, not a tailwind for ARPU growth.
To fix this, companies want to introduce differentiated tiered pricing and network slicing for 5G. Jio already does this in Fixed Wireless, identifying network slicing as a big 5G monetization opportunity.
PART 2: DIGITAL PRODUCTS & CROSS-SELLING WAR
This is where Jio calls itself a "Tech Platform". The core thesis: Acquire with data, monetize with products.
Jio’s Strategy
Jio onboarded 2G users with JioPhone, then cross-sold JioTV, JioSaavn, JioMart, and JioStar apps. Now it’s working on its AI layer - Jio Brain.
Reliance noted that its Digital Services arm is growing faster than the Data Plans arm. Jio is also building the world’s largest data center in Jamnagar with 168 MW capacity.
Airtel’s Strategy
Airtel is offering premium products like Wynk Music, Xstream, and the Airtel Payments App to increase revenue per user. It wants to grow its Data Center arm (Nxtra) capacity to 1 Gigawatt in 4 years, targeting a market share jump from 12% to 25% via 56 world-class data centers.
Airtel is also prioritizing Home Services and the Cloud Business. Furthermore, Airtel Money NBFC recently received RBI approval, signaling that Fintech is next.
Vodafone Idea & BSNL
Both are not doing revenue diversification yet. Their focus remains squarely on 4G Expansion:
- BSNL will focus on 4G expansion in FY27, adding 20,000 sites.
- Vodafone Idea converted 86% of its network to 4G and plans to add 60,000-70,000 more 4G sites in the next 12-18 months.
Capex is huge: FY26 Capex stood at ₹8,800 Cr for Vodafone Idea, ₹31,000 Cr for Airtel, and ₹34,000 Cr for Jio. Vodafone Idea plans an additional ₹45,000 Cr over the next 3 years.
After the 2021 Telecom Reforms, capex capacity increased because companies now pay 8% AGR only on Telecom Revenue, not Total Revenue, alongside the removal of Spectrum Usage Charges.
However, high capex means ROCE (Return on Capital Employed) is flat or falling for most, with Airtel being an exception. India Ratings indicates that to achieve a healthy 15% ROCE, the sector needs to increase ARPU by ₹35 to ₹40, meaning another price hike may be right around the corner.
PART 3: THE SATELLITE COMMUNICATIONS WAR
The war has now shifted from towers on the ground straight into space.
Unlike terrestrial telecom spectrum which uses auctions, the government chose Administrative Allocation for satellite spectrum because space spectrum is inherently shared.
Interestingly, both Airtel and Jio initially pushed for auctions to construct barriers against foreign players, but that did not materialize.
The Starlink Twist (March 2025): both Airtel and Jio signed partnerships with Starlink to sell Starlink terminals at their retail outlets. The very global competitor they fought against, they are now partnering with on the ground.
However, they are simultaneously building out their own Satcom arms:
- Airtel: Invested $1 Billion alongside the UK Govt to rescue OneWeb in 2020. In 2022, OneWeb merged with France’s Eutelsat to become OneWeb Eutelsat.
- Jio: Formed a JV with Luxembourg’s SES. Because SES primarily uses Medium Earth Orbit (MEO)—which features higher latency than Starlink’s Low Earth Orbit (LEO)—Jio announced plans at Reliance’s 49th AGM to build their own proprietary LEO Satellite Constellation.
Today, Airtel, Jio, and Starlink all hold the necessary regulatory approvals and are waiting for the final spectrum allocation. The government has also launched the Digital Bharat Nidhi initiative to improve satellite connectivity across rural areas.
CONCLUSION
India’s telecom sector has entered an incredibly dynamic phase. The war was once fought over ground-based Network Towers and coverage; today, it is transitioning directly into orbit.
Right now, Airtel and Jio dominate while Vodafone Idea and BSNL fight to stay relevant. Yet, with Starlink officially entering the playing field, the long-term competitive dynamics remain open-ended.
Combined with the aggressive diversification into Digital/VAS products and core plan monetization, the next few years will be fascinating to track.
What do you think — Who will win the long game: Airtel or Jio? Let us know your thoughts in the comments below!
FAQ: Frequently Asked Questions
Q1: Why is Jio claiming to be a technology company rather than a telecom player?
Jio positions itself as a tech platform because it isn't just selling data pipelines. Through its DRHP details, Jio highlights its reliance on proprietary digital structures, massive patent filings (6,817), AI software architecture (Jio Brain), and a rapid rollout into large-scale data hosting hubs.
Q2: What is ARPU and why does Airtel lead Jio in this metric?
ARPU stands for Average Revenue Per User. Airtel operates on a 'premiumization' model, aiming to extract higher revenue per user by targeting urban, high-value consumers and cross-selling premium digital add-ons. Jio targets volume, capturing a broader segment with slightly lower entry prices.
Q3: When are the next major telecom tariff hikes expected in India?
Industry analyses point towards another potential 15% tariff hike arriving around the Q2 to Q3 cycles of FY27 to restore standard corporate ROCE metrics to healthier targets near 15%.
Q4: Why are Airtel and Jio partnering with Starlink if they are rivals?
Instead of locking heads in a purely exclusionary spectrum battle, Jio and Airtel adjusted dynamically in March 2025 to sell Starlink satellite terminals via their retail networks, combining Starlink's space infrastructure with their own extensive retail distribution footprints.
Q5: What is the capacity goal for Airtel's data center ecosystem?
Through its data center subsidiary Nxtra, Airtel secured global capital backing to scale up operations from ~300 MW to a massive 1 Gigawatt footprint over the coming years, aiming for a 25% domestic market share.
