Vi (Vodafone Idea) and Meta launched Silent Mobile Verification (SMV) on June 4, 2026. SMV is a network-based authentication technology that verifies a Vi subscriber’s mobile number directly through Vi’s telecom carrier network in the background. This launch covers three Meta platforms: WhatsApp, Facebook, and Instagram, and applies to all 198.5 million Vi subscribers across India.
SMV removes the need to enter any one-time password (OTP), wait for an SMS code, or switch between apps during login, registration, or account recovery. This OTP-free mobile number verification works in the background through Vi’s carrier network without any action from the user.
What is Vi Silent Mobile Verification (SMV)?
Silent Mobile Verification is a network-based authentication technology that validates a user’s mobile number in the background directly through the telecom carrier network, without requiring OTP entry, password input, or any manual step from the user.
One-time passwords (OTPs) are numeric codes sent to a phone number via SMS to confirm a user’s identity during login or registration. Traditional authentication systems generate and deliver this code via SMS, ask the user to open the message, copy the code, and paste it into the app within a fixed time window. Vi SMV replaces this entire process with a background network-level check.
SMV uses a standardized network API (Application Programming Interface) to match the mobile number a user is verifying against the active SIM and data session on Vi’s network. The check completes within milliseconds. The user sees no prompt and performs no action.
Vi is the first Indian telecom operator to activate SMV at the consumer retail level for Meta platforms. The announcement came from both companies jointly on June 4, 2026, marking a first-of-its-kind integration in India’s telecom and social media ecosystem.
How Does Vi SMV Work on WhatsApp, Facebook and Instagram?
When a Vi subscriber opens WhatsApp, Facebook, or Instagram on an active Vi cellular connection, the Meta app sends a verification request to Vi’s network API. Vi’s network checks whether the active SIM and data session match the registered phone number and returns a pass or fail result to the app within milliseconds, with no action needed from the user.
Vi SMV is built on two technical standards: the GSMA Open Gateway framework and the CAMARA Number Verification API.
The GSMA Open Gateway is a global initiative that provides standardized network API access so developers and digital platforms can build authentication services that work across participating mobile operators worldwide.
The CAMARA Number Verification API is an open-source technical standard developed under the GSMA and the Linux Foundation. It allows telecom networks to expose their subscriber identity data to authorised apps securely, without revealing sensitive personal information.
The verification flow for Vi SMV works in three steps:
- The Meta app (WhatsApp, Facebook, or Instagram) sends a verification request to Vi’s network via the CAMARA Number Verification API.
- Vi’s network checks whether the active mobile data session on the user’s device is linked to the phone number being verified.
- Vi’s network returns a pass or fail result to the Meta app. No OTP is generated. No SMS is sent.
The user experiences this as instant access with no visible interruption.
What Happens During New User Registration with Vi SMV?
A new user opening WhatsApp or Facebook for the first time on a Vi cellular connection goes through SMV automatically. The app confirms the mobile number in the background without prompting the user to enter or receive any code. Registration completes faster with fewer manual steps than the traditional OTP flow.
How Does Vi SMV Handle Account Login and Account Recovery?
Vi SMV covers five verification scenarios: new user registration, mobile number validation, account login, re-login after a session gap, and account recovery. All five scenarios run the same background network check through Vi’s carrier API. For account recovery, SMV confirms the SIM is physically present and active on the device before unlocking account access. This step prevents unauthorised account takeovers by third parties who do not have the physical SIM.
Why Did Vi Partner with Meta to Launch SMV in India?
Vi partnered with Meta because India is the largest market globally for WhatsApp, Facebook, and Instagram. With 198.5 million Vi subscribers and rising digital fraud levels, both companies identified network-based authentication as the most scalable fraud-reduction solution for Indian retail users at this scale.
Digital fraud in India reached a critical level by 2025. According to the GSMA India Consumer Scam Report 2025, 53 percent of Indian consumers have been scammed. The Indian Cyber Crime Coordination Centre (I4C), under the Ministry of Home Affairs, recorded over 25 lakh cybercrime complaints in 2025 alone. Digital fraud losses in India crossed Rs 9,000 crore in 2025, with banking sector losses exceeding Rs 8,200 crore.
OTP-based SMS verification was the entry point for many of these fraud cases. Phishing attacks, call-merge fraud, SIM swap attacks, and malicious apps all specifically target SMS OTPs because the user must receive, read, and manually enter the code during the verification window.
Abhijit Kishore, CEO of Vodafone Idea, stated: “Telecom networks are increasingly playing an important role in enabling safer digital experiences. With millions of consumers relying on Vi’s secure telecom network every day, we can build these experiences on a scale.”
Arun Srinivas, Managing Director and Country Head of Meta India, stated: “Bringing network-based authentication is a critical step forward in making verification simpler, seamless and more secure for users across our platforms.”
The launch also aligns with new Reserve Bank of India (RBI) authentication guidelines effective from April 1, 2026. These guidelines require banks and digital platforms to move beyond single-method OTP verification and offer dynamic, multi-factor authentication alternatives for digital transactions.
Does Vi SMV Protect Against OTP Fraud and Phishing?
Yes. Vi SMV protects against OTP fraud and phishing because no OTP is generated or delivered at any point during network-level verification. Phishing attacks, call-merge fraud, SIM swap attacks, and social engineering scams all require the user to receive and share an OTP. SMV removes OTP from the verification flow entirely.
Three specific fraud types are neutralised by SMV:
SIM swap fraud is a method where a criminal ports a victim’s phone number to a new SIM card to intercept OTPs and gain access to the victim’s accounts. Vi SMV neutralises SIM swap fraud by verifying the active SIM on the physical device in real time through Vi’s carrier network. A ported SIM on another device does not produce a matching active data session, and the verification fails immediately.
Phishing is a method where criminals direct users to fake websites or apps that capture OTPs entered by the victim. Vi SMV neutralises phishing because the user enters no OTP at any point. There is no code for the fraudulent site to capture.
Call-merge fraud is a method where criminals trick users into sharing OTPs during a phone call by merging a conference call with a bank’s or app’s OTP delivery line. Vi SMV neutralises call-merge fraud because the OTP generation and delivery step is removed from the authentication process completely.
Password-less authentication through Vi SMV reduces the digital identity theft surface for 198.5 million Vi subscribers across all three Meta platforms.
How is Vi SMV Different from What Jio and Airtel Currently Offer?
Vi is the only Indian telecom operator to launch a consumer-facing SMV integration directly with Meta platforms as of June 2026. Jio and Airtel participate in GSMA Open Gateway for enterprise and banking developer use cases but have not announced a default retail-level SMV integration for WhatsApp, Facebook, or Instagram.
The table below shows the current status of network-based authentication across all three Indian operators:
| Feature | Vi (Vodafone Idea) | Reliance Jio | Bharti Airtel |
|---|---|---|---|
| Consumer-Facing Meta SMV | Yes (Live, June 2026) | No | No |
| GSMA Open Gateway | Yes | Yes (October 2025) | Yes |
| API Standard | CAMARA | CAMARA | CAMARA |
| Primary Focus | Retail consumer authentication | Enterprise developer APIs | Enterprise and banking verification |
| SIM Swap API | Yes | Yes (federated) | Yes (federated) |
| Number Verification API | Yes, and Meta SMV | Developer access only | Developer access only |
All three operators use the same underlying GSMA Open Gateway and CAMARA API framework. The difference is deployment depth.
Vi converted this developer-level API access into a default, automatic, real-time authentication experience for retail consumers on Meta’s three platforms. Jio and Airtel have exposed the same APIs to enterprise developers and banks, but no consumer-facing Meta rollout has been announced by either operator.
Bharti Airtel’s current focus is enterprise fraud prevention. Airtel has used AI-powered tools to block over 53 billion spam calls and 2.5 billion spam SMS messages according to its official India Mobile Congress 2025 statement.
Reliance Jio joined the GSMA Open Gateway initiative in October 2025 and participates in the federated SIM Swap API used by banks, but has not announced a direct consumer Meta partnership.
Vi’s first-mover advantage is in consumer application delivery. By integrating directly with Meta at the default retail level, Vi turns an abstract developer API into an immediate, daily-use security upgrade for nearly 200 million subscribers.
Does Vi Silent Mobile Verification Work on Wi-Fi?
No. Vi SMV does not function when a user is connected to a Wi-Fi network with mobile data turned off. SMV requires an active Vi cellular data connection to verify the SIM and mobile session through Vi’s carrier network. A Wi-Fi connection does not pass through Vi’s mobile network infrastructure.
This is a design constraint of all CAMARA-based network verification systems, not a limitation specific to Vi. The authentication process relies on matching the device’s active mobile data session to Vi’s carrier subscriber records. A Wi-Fi session routes internet traffic through the home router or public hotspot’s broadband connection, which bypasses Vi’s mobile network entirely. Vi cannot perform the carrier-level verification check on a non-cellular session.
What Happens When Vi SMV Cannot Verify in the Background?
When a Vi user is on Wi-Fi or has mobile data turned off, the Meta app falls back to traditional OTP verification automatically. The user receives an SMS OTP and completes the verification step manually. The fallback OTP process is identical to the standard authentication flow used before SMV was introduced. The SMV layer activates again the next time the user is on an active Vi cellular data connection.
Which Vi Users Can Use SMV on Meta Platforms?
All Vi subscribers accessing WhatsApp, Facebook, or Instagram on an active Vi cellular data connection are eligible for SMV from June 4, 2026. No app update, no settings change, and no manual activation is required. SMV activates automatically in the background when the Meta app initiates a verification request.
Vi’s subscriber base covers 198.5 million users across India as of April 2026. The SMV capability activates automatically when two conditions are met at the same time: the user is on an active Vi cellular data connection and the Meta app initiates a verification event such as login, registration, re-login, or account recovery.
Dual SIM users must keep one condition in mind. SMV activates only when the Vi SIM is set as the active data SIM on the device. A user with a Vi SIM for voice calls and a Jio or Airtel SIM set as the primary data connection will not experience Vi SMV on Meta apps. The Meta app’s data request routes through the non-Vi network, and Vi’s carrier system cannot perform the background verification check on that data session.
This dual SIM limitation is significant in the Indian market. India has one of the highest dual SIM usage rates in the world, with many users actively switching their data SIM between carriers based on network speed and data pack availability.
Frequently Asked Questions on Vi SMV
Vi SMV is a new technology for most Indian consumers. The following questions address the most common points of confusion about how it works, its limitations, and its future scope.
Does Vi SMV Store My Personal Data?
Vi SMV verifies that the mobile number matches the active SIM and data session on Vi’s network. The check produces a pass or fail result. As of June 2026, Vi and Meta have not published specific data retention policies for SMV API verification records in their public announcements. Users can refer to Vi’s official privacy policy and Meta’s data policy for complete information on data handling.
Will Vi SMV Replace OTP Completely?
No. Vi SMV does not replace OTP completely. SMV is the primary verification method when a Vi user is on an active Vi cellular data connection. OTP remains the fallback method when SMV cannot verify in the background. This includes sessions on Wi-Fi, sessions where mobile data is off, and sessions where the active data SIM is not Vi.
Can Vi SMV Be Used on Dual SIM Phones?
Yes, with one condition. SMV works on dual SIM phones when the Vi SIM is set as the active mobile data SIM on the device at the time the Meta app initiates verification. Setting the data SIM to Jio or Airtel deactivates Vi SMV for that session and reverts the authentication to OTP delivery via SMS.
When Will Vi Expand SMV to Other Apps?
Vi has announced plans to extend network-based authentication capabilities to more third-party applications and ecosystem partners beyond Meta. No specific timeline or confirmed list of partner apps has been published as of June 2026. Vi CEO Abhijit Kishore confirmed that Vi will continue building authentication, trust, and intelligence solutions that use Vi’s telecom network capabilities for a broader set of digital platforms. Smaller third-party apps may face higher per-call API costs compared to bulk SMS OTP costs, which may affect the pace of adoption across the wider Indian app ecosystem.
Vi SMV and the Future of Trusted Digital Infrastructure in India
Vi’s SMV launch with Meta is a step in a larger shift in how Indian telecom networks are used for digital identity verification. The GSMA Open Gateway initiative now includes all three major Indian operators, and federated CAMARA APIs are already active for SIM Swap detection and Number Verification for banks.
Network-based authentication gives telecom carriers a direct role in India’s digital identity verification framework. This role sits alongside government-led identity systems and extends the security layer to widely used consumer apps.
Vi’s plan to expand SMV beyond Meta to more third-party platforms signals that the network-based authentication model will become standard practice in Indian telecom over the next few years. For Indian consumers, this means fewer OTPs, fewer fraud opportunities, and faster access to digital services across platforms.
