TRAI Mandate Squeezes Telecom ARPU
India's Telecom Regulatory Authority (TRAI) has ordered telecom companies to offer voice and SMS-only recharge plans. This regulatory change directly challenges the industry's strategy for growing Average Revenue Per User (ARPU). The aim is to provide options for customers who don't need data, preventing them from being forced into bundled plans with services they won't use. However, for a sector that has relied on data usage, 5G adoption, and premium plan upgrades to increase ARPU, this requirement risks fragmenting revenue streams.
Analysts expect Indian telecom ARPU to climb past ₹200 and reach about ₹220 by the end of fiscal year 2026, fueled by earning money from 5G and price increases. Major players like Bharti Airtel reported an ARPU of ₹259 in Q3 FY26, Reliance Jio at ₹213.7, and Vodafone Idea at ₹186. The new rules could reduce these gains by requiring cheaper, unbundled voice and SMS options. This might slow the important shift from 2G to advanced 4G and 5G networks.
Jio, Airtel, Vi Face Unequal Impact
This regulatory shift will likely affect India's main telecom companies differently. Reliance Jio, with its 4G/5G-only network and nearly 493 million customers, might be less impacted than operators still serving many feature phone users. Bharti Airtel, which has the highest ARPU at ₹259 and about 472 million customers, faces a similar challenge in maintaining its premium pricing. Both companies have been actively promoting 4G and 5G upgrades, a strategy that could be dampened by the availability of cheaper, basic service plans.
Vodafone Idea (Vi), already under significant financial strain with fewer than 200 million customers and an ARPU of ₹186, faces a more difficult situation. While the mandate could help its low-income customers, it risks further reducing its ability to fund network upgrades and pay down debt. Vi has a market capitalization of ₹95,017 crore as of April 6, 2026. In comparison, Bharti Airtel's market cap is ₹10,92,128 crore with a P/E of about 30.41, and Reliance Industries (Jio) has a market cap around ₹17.67 lakh crore with a P/E of roughly 18.12.
TRAI Tightens Rules on Basic Plans
TRAI's move follows feedback that previous mandates requiring at least one voice and SMS-only plan were not enough, as operators offered limited options with long validity periods. The regulator also noted these older plans did not reflect a proportional reduction in price when data benefits were removed. TRAI is now demanding a "proportionally lower price" for voice and SMS-only packs. This action shows TRAI's commitment to consumer choice and affordability, especially for the estimated 150 million users still on feature phones or using basic services.
However, some operators see this as a step that could slow digital progress and reverse the trend of users moving to data-focused services. The sector is managing high investment costs for 5G rollout and considerable debt. ARPU growth is therefore crucial for financial stability. The overall Indian telecom sector's P/E ratio is about 31.7x, suggesting investors expect future growth, but this new mandate could introduce uncertainty.
Unbundling Plans Risk Stagnant Revenue
The main risk for telecom companies is the potential for ARPU to stagnate or decline. By requiring services to be unbundled, TRAI's mandate could discourage users from upgrading to more expensive data-inclusive plans, including the 4G and 5G services that are key future revenue drivers. This could create an obstacle for telcos' plans to recover their 5G investments. The pricing of these new voice and SMS-only plans will be critical. If they are not significantly cheaper than bundled offers, the intended benefit for low-income users may not be realized, and operators might simply remove data bundles from existing voice plans to comply.
Furthermore, the current industry ARPU range of ₹180-₹200 has shown little change despite price increases and 5G investments. This suggests market saturation or that customers are very sensitive to prices. A forced shift toward lower-tier offerings could worsen this trend. For Vodafone Idea, which carries heavy debt, any impact that suppresses ARPU could severely affect its ability to manage its over ₹2.09 lakh crore in debt.
Telcos Face Choice vs. Revenue Balance
Telecom companies must now adjust their product offerings to meet TRAI's directive while trying to protect their income. This will likely involve new pricing strategies for the voice and SMS-only plans, ensuring they appeal to the target audience without taking away business from higher-margin data services. The industry has already seen operators introduce new voice and SMS-only plans, such as Airtel's ₹499 and ₹1,959 plans, and Jio's ₹458 and ₹1,958 offerings, showing an initial response to the mandate.
The success of this regulation will depend on operators' ability to effectively segment their markets and on TRAI's ongoing oversight to ensure these plans offer real cost savings. The sector's future growth will depend on balancing the need to drive data adoption and 5G revenue with the regulatory push for basic service access.
