eSIM adoption in India: what Australian readers need to know

India's telecommunications market has shifted dramatically in the past three years, with embedded SIM technology moving from a premium feature to a mainstream option across the subcontinent. For Australians who travel to India for business, source smartphones from regional sellers, or simply watch the global mobile industry, the pace of change offers useful lessons. It also surfaces some sharp contrasts with how Telstra, Optus, and TPG operate at home.

The Australian market embraced embedded SIM early. Most flagship handsets sold in Sydney, Melbourne, or Brisbane ship with both physical SIM trays and digital profiles, and the local carriers built their app-based onboarding flows long before many of their regional counterparts. India followed a different path, with QR code activation, biometric verification, and a regulatory framework that prioritised centralised identity checks. Understanding those differences helps Australian readers put global connectivity trends into perspective, particularly as more regional players in Southeast Asia and the Pacific look to similar models.

Carrier support and the Indian eSIM landscape

Four operators carry the bulk of India's mobile traffic: Reliance Jio, Bharti Airtel, Vodafone Idea (now branded Vi), and the state-run BSNL. Of these, Jio and Airtel have been the most aggressive in rolling out eSIM-compatible networks. Jio launched embedded SIM support for postpaid users in 2022 and expanded it to prepaid customers in major metros the following year. Airtel followed a similar trajectory, adding QR-based profile downloads across Android and iOS devices within months.

Vi has lagged slightly, with embedded SIM functionality still patchy outside tier-one cities and limited to higher-tier postpaid plans. BSNL, the government operator, only began trialling the technology in late 2024, partly because its subscriber base skews toward price-sensitive rural users who have been slower to upgrade hardware. For Australians used to uniform nationwide coverage from the major carriers, this fragmentation is a reminder that embedded SIM availability depends heavily on which operator and which circle (India's regional licensing zones) a user signs up with. Circles vary by state, and a Jio eSIM activated in Tamil Nadu may not seamlessly port to Jammu and Kashmir without additional paperwork.

The picture gets even more layered once enterprise customers enter the conversation. Indian corporations with distributed workforces have driven much of the demand for eSIM adoption in India, particularly in the banking, logistics, and ride-hailing sectors. These organisations often negotiate directly with carriers for bulk profile provisioning, bypassing the consumer-facing QR flow entirely.

Costs, plans and roaming economics

Pricing structures in India look very different from Australian postpaid plans. A typical Jio or Airtel prepaid eSIM starts at around 199 rupees per month, which converts to roughly 3.60 Australian dollars. Bundled data packages offer between 1.5 GB and 24 GB daily depending on the recharge tier, with voice and SMS often included by default. By comparison, the cheapest Telstra prepaid plan with eSIM starts at AUD 25, and Optus prepaid sits at AUD 20 for similar inclusions, though Australian plans typically lack the generous daily data allowances seen in India.

For Australian travellers, the math becomes interesting when roaming comes into play. Telstra's international roaming passes for India hover around AUD 10 per day, while Optus charges AUD 12 for a 24-hour pass. Local Indian eSIM providers such as Airalo, Holafly, and Nomad offer regional data-only plans starting from USD 5 for seven days, though these typically exclude Indian phone numbers and incoming SMS verification codes. Many frequent flyers based in Perth and Adelaide have started keeping a secondary Indian eSIM active specifically for receiving OTPs from banking apps and government portals. New users exploring carrier promotional recharge bonuses often find that bundled first-month credits can stretch a travel budget further than expected.

Long-stay visitors and students on Australian visas heading the other direction often report the opposite finding. Buying an Indian eSIM on arrival can cost less than a week of Australian roaming charges, even after accounting for the verification overhead. The economics make a strong case for dual-SIM setups that bridge both markets without committing to either carrier exclusively.

Device compatibility and activation flow

Hardware compatibility is no longer the obstacle it once was. Every iPhone from the XS onwards supports eSIM, and Google's Pixel lineup has offered dual-SIM functionality since the Pixel 3. On the Android side, Samsung's Galaxy S and Z series devices ship with embedded SIMs across all variants sold in India. Looking ahead, the first developer preview of Android 16 suggests even tighter integration between carrier profile management and the operating system's settings layer, with new APIs that may simplify multi-profile switching.

Activation itself works through a QR code generated by the carrier after identity verification. Indian regulations require every new mobile connection to be linked to Aadhaar, the country's biometric ID system, or a valid passport for foreign nationals. Once verified, the carrier emails or SMSes a QR code that the user scans through the phone's settings menu. The scanning process takes roughly five minutes, although network provisioning can add another 30 minutes before the line becomes fully active. Dual-SIM functionality works well, with most Indian users running a physical SIM for their primary number and an embedded profile for travel or secondary lines. Confirming band support for Australian LTE and 5G frequencies remains essential, particularly the n78 band that Airtel and Jio use for their standalone 5G rollouts.

Apple Watch and cellular-equipped wearables add another layer. Indian carriers now support number-sharing between an iPhone and an Apple Watch through the same eSIM profile, which means a single QR activation can extend connectivity to a wearable without a separate SIM purchase. That feature arrived in Australia through Telstra and Optus a year earlier, but India's deployment has caught up quickly.

Rules, regulation and consumer protections

India's Department of Telecommunications sets the rules around embedded SIM provisioning, while the Telecom Regulatory Authority of India (TRAI) handles tariff oversight and consumer complaints. One distinctive feature is the mandatory KYC (Know Your Customer) process, which applies equally to embedded profiles and physical cards. Foreign visitors purchasing an Indian eSIM must present their passport and visa documentation, and the carrier is required to retain a copy for verification purposes. This makes walk-in store visits almost unavoidable for tourists who want a local number.

The regulatory framework also caps the number of profiles a single device can store, though most users will never approach the limit. TRAI's recent interventions have focused on curbing spam and fraudulent SMS traffic, with new rules requiring commercial messaging to be sent through registered headers. For Australians, the equivalent body is the Australian Communications and Media Authority (ACMA), which operates with a lighter touch on consumer pricing but enforces stricter rules around number porting, emergency service access, and the recent SIM-swap fraud reforms introduced in 2024.

Number porting itself tells an interesting story. Australian carriers must complete a port within three business days under ACMA rules. India has set a 72-hour target for embedded SIM porting, but real-world timelines often stretch longer because of the manual verification steps still embedded in the process. Both systems aim for the same outcome but rely on very different checks.

What this means for Australians planning ahead

The practical takeaways fall into a few categories. Travellers heading to Mumbai, Delhi, or Bengaluru for short business trips will find the local ecosystem mature enough to handle their needs, especially if they book a data-only plan through a global reseller before departure. Those relocating for work should expect a more thorough onboarding process, with in-store visits often required for the biometric verification step. Importing Indian-market smartphones into Australia is legal under most circumstances, but buyers should verify that the device supports Australian LTE and 5G bands before committing, since some Indian variants omit key frequencies. Reading through handset reviews on regional tech sites can help flag these omissions before purchase.

Remote workers and digital nomads based in Australia who spend extended periods in cities like Goa, Hyderabad, or Chennai should consider keeping both an Australian physical SIM and an Indian eSIM active on the same handset. The setup takes an hour of configuration but pays off whenever banking apps, ride-hailing services, or government portals demand a local number for verification. Splitting voice traffic between the two also helps avoid international call rates that catch many first-time visitors off guard.

Australian readers who follow this space will notice that India's approach prioritises identity verification and centralised control, while local carriers have leaned more heavily on app-based self-service. Neither model is objectively superior, and each offers trade-offs in convenience, security, and cost. Watching how India's fragmented carrier landscape continues to evolve over the next few years will give useful signals about where the broader Asia-Pacific market is heading next, and how regulators balance innovation against consumer protection in a connected region.
