Growing M2M Subscriber Base, Rising Prepaid Tariffs and Evolving Consumer Behaviour Narrow Revenue Gap, Though Pricing Differences Are Expected to Continue

India's telecom industry is undergoing a significant transformation as Average Revenue Per User (ARPU) from prepaid subscribers has overtaken postpaid ARPU for the first time in the sector's history. While the development marks a major milestone in the evolution of the country's mobile services market, industry experts believe it does not indicate that prepaid and postpaid tariff structures are becoming identical.

Instead, analysts suggest that the convergence in ARPU is largely the result of structural changes in the telecom ecosystem, particularly the rapid growth of Machine-to-Machine (M2M) connections, changing customer preferences, multiple tariff hikes in prepaid plans and the increasing adoption of digital services. These factors have altered the traditional revenue profile of telecom operators, making ARPU a more complex metric than it was a few years ago.

Although prepaid users are now generating marginally higher average revenue than postpaid subscribers, operators are expected to continue maintaining premium pricing for postpaid customers by offering exclusive benefits such as bundled OTT subscriptions, international roaming, family plans and enterprise services.

A Historic Turning Point for India's Telecom Sector

For decades, postpaid mobile subscribers consistently generated higher revenue for telecom operators because they typically belonged to higher-income customer segments and opted for premium service plans.

However, this long-standing trend changed during June 2025 and was repeated in March 2026, when prepaid ARPU marginally exceeded postpaid ARPU.

Industry experts believe this is more than just a statistical event—it reflects the changing structure of India's telecom industry.

The shift also highlights how operators have successfully improved monetisation within the prepaid segment through tariff revisions and increased digital consumption.

Understanding Average Revenue Per User (ARPU)

ARPU is one of the most closely watched performance indicators in the telecom sector.

It measures the average monthly revenue generated from each subscriber and serves as an important indicator of a telecom operator's pricing power, profitability and customer value.

A higher ARPU generally translates into:

• Stronger revenue growth.

• Better operating margins.

• Greater cash flow generation.

• Improved return on network investments.

For investors, sustained ARPU growth is often viewed as a positive sign of improving business fundamentals.

How the Revenue Gap Has Narrowed

According to industry experts, the change in revenue dynamics over the past five years has been remarkable.

March 2021

• Postpaid ARPU exceeded prepaid ARPU by approximately ₹129.

March 2026

• Prepaid ARPU exceeded postpaid ARPU by around ₹1.9.

The reversal illustrates how India's prepaid market has become significantly more profitable following repeated tariff increases and higher customer spending.

Prepaid Revenue Has More Than Doubled

The primary driver behind the ARPU crossover has been the sharp increase in prepaid revenue.

Industry estimates indicate that:

• Prepaid ARPU has grown by more than 100% over the past five years.

During the same period:

• Postpaid ARPU declined by nearly 14%.

The contrasting trends reflect changes in subscriber composition rather than weakening demand for postpaid services.

Machine-to-Machine (M2M) Connections Are Reshaping Postpaid Revenue

One of the biggest contributors to the decline in average postpaid ARPU is the rapid expansion of Machine-to-Machine (M2M) connectivity.

M2M SIM cards are increasingly used across industries for connected devices such as:

• Smart electricity meters.

• Connected automobiles.

• GPS tracking systems.

• Payment terminals.

• Industrial automation equipment.

• Healthcare monitoring devices.

• Smart city infrastructure.

Most of these connections operate under postpaid billing arrangements but generate relatively low monthly revenue.

As millions of such SIM cards are added every year, they reduce the overall average revenue generated from postpaid subscribers.

India's Connected Device Ecosystem Is Expanding Rapidly

According to industry estimates, India had more than 131 million M2M subscribers as of May 2026.

The segment continues to grow rapidly due to increasing investments in:

• Internet of Things (IoT).

• Smart manufacturing.

• Digital infrastructure.

• Connected transportation.

• Utility automation.

• Smart agriculture.

As India's digital economy expands, M2M connections are expected to become an increasingly important revenue stream for telecom operators.

Postpaid Customers Continue to Enjoy Premium Services

Despite the statistical decline in ARPU, postpaid remains a premium offering targeted at higher-value customers.

Most postpaid plans continue to include benefits such as:

• Unlimited voice and data.

• International roaming.

• OTT streaming subscriptions.

• Family plans.

• Priority customer support.

• Device financing options.

• Business connectivity solutions.

These value-added services differentiate postpaid plans from prepaid offerings and support premium pricing.

Postpaid Subscriber Base Continues to Grow

Although prepaid dominates India's telecom market, postpaid adoption has gradually increased over recent years.

According to Telecom Regulatory Authority of India (TRAI) data:

• Around 10% of India's 1.3 billion mobile subscribers now use postpaid services.

Previously, postpaid penetration remained between 8% and 9%.

The increase reflects stronger adoption among:

• Urban professionals.

• Corporate users.

• Enterprise customers.

• High-data consumers.

Why Tariff Differences Will Continue

Experts believe the narrowing ARPU gap should not be interpreted as the disappearance of pricing differences between prepaid and postpaid plans.

Several structural factors support continued tariff divergence.

Different Customer Segments

Prepaid users typically prioritise affordability and flexibility.

Postpaid customers value convenience, premium services and bundled offerings.

Enterprise Demand

Corporate clients and M2M users continue to prefer postpaid billing for operational convenience.

Value-Added Services

Postpaid plans increasingly bundle:

• Entertainment subscriptions.

• Cloud storage.

• International roaming.

• Priority customer care.

These benefits justify higher pricing despite the lower average ARPU created by M2M connections.

Tariff Hikes Have Improved Prepaid Monetisation

India's telecom operators have implemented multiple prepaid tariff revisions over the past two years.

These increases have significantly improved revenue per prepaid subscriber while strengthening industry profitability.

Higher prepaid ARPU enables operators to:

• Invest in network expansion.

• Accelerate 5G rollout.

• Improve operating margins.

• Enhance customer experience.

• Strengthen balance sheets.

5G Will Create New Revenue Opportunities

The next phase of ARPU growth is expected to be driven by 5G-enabled digital services rather than traditional voice tariffs.

Potential growth areas include:

• Cloud gaming.

• AI-powered applications.

• Enterprise connectivity.

• Smart manufacturing.

• Industrial IoT.

• Edge computing.

• Private 5G networks.

Telecom companies are increasingly positioning themselves as digital service providers rather than simply mobile connectivity operators.

What This Means for Investors

The changing ARPU landscape reflects the evolution of India's telecom industry from subscriber-led growth to value-driven growth.

Investors should increasingly focus on:

• Sustainable ARPU expansion.

• Enterprise connectivity.

• Digital service monetisation.

• 5G adoption.

• IoT ecosystem growth.

• Operating margin improvement.

Companies capable of successfully monetising advanced digital services may generate stronger long-term shareholder returns.

Key Challenges Ahead

Despite encouraging revenue trends, telecom operators continue to face several challenges.

These include:

• High capital expenditure for 5G deployment.

• Intense competition.

• Spectrum costs.

• Network investments.

• Regulatory compliance.

• Pressure to improve return on capital.

Balancing affordability with profitability will remain critical as operators continue expanding their digital ecosystems.

Outlook

The crossover of prepaid ARPU above postpaid represents a historic milestone in India's telecom sector, reflecting deep structural changes rather than a simple shift in consumer preferences. The rapid growth of machine-to-machine connections, stronger prepaid monetisation, expanding digital consumption and the increasing adoption of connected technologies have fundamentally altered the industry's revenue profile.

Looking ahead, telecom operators are expected to continue differentiating prepaid and postpaid offerings through premium services, enterprise solutions and digital value-added products. While headline ARPU figures may continue to converge, pricing strategies are likely to remain distinct as operators pursue higher profitability through 5G, IoT and AI-driven digital services. For investors, the sector's long-term growth story will increasingly depend on operators' ability to generate higher revenue from each customer while successfully capitalising on India's accelerating digital transformation.
