ai: Google looks to tackle longstanding RCS spam in India — but not

Google is intensifying its efforts to combat persistent spam on its Rich Communication Services (RCS) platform in India, announcing a strategic partnership with Bharti Airtel. The collaboration, unveiled Sunday, integrates Airtel’s robust network-level spam filtering directly into the RCS ecosystem, aiming to significantly strengthen protections against unwanted messages and fraudulent activity within the country.

India's Unique Spam Challenge

India presents a particularly formidable challenge in the fight against messaging spam and fraud. This environment is fueled by the nation’s massive mobile user base, the rapid acceleration of digital payments, and aggressive enterprise marketing practices across various channels. The scale of the issue led to widespread complaints about unsolicited advertisements on Google’s RCS, primarily delivered through the Google Messages app. These concerns were significant enough to prompt Google to temporarily pause business promotions on the platform in India during 2022. Despite these past measures, users continue to express frustration over spam messages in Google Messages, indicating that the problem has persisted.

Airtel's Strategic Integration

Bharti Airtel, India's second-largest telecom operator boasting over 463 million subscribers, had previously adopted a cautious approach to deeper alignment with Google's RCS initiatives. A spokesperson for Airtel confirmed that the carrier had not onboarded Google for RCS until it could ensure that all messages were routed through its proprietary spam filter, highlighting legitimate concerns about escalating fraud risks. This new partnership directly addresses that prerequisite.

Under the terms of the agreement, Airtel’s sophisticated network intelligence will be seamlessly combined with Google’s RCS platform. This integration is designed to enable real-time checks on business messaging traffic, incorporating crucial functions such as sender verification, advanced spam detection algorithms, and stringent enforcement of users’ do-not-disturb (DND) preferences. Airtel has described this initiative as a “global first” for embedding a telecom operator's spam filtering directly into an over-the-top messaging platform, though specific comparative details were not disclosed by the companies.

Airtel's commitment to anti-spam measures is well-established; over the past year, its AI-led systems have actively blocked more than 71 billion spam calls and 2.9 billion spam messages. These efforts have been instrumental in driving a significant nearly 69% reduction in fraud-related financial losses experienced on its network, demonstrating the carrier's capability in this domain.

Broader Implications for RCS

This innovative model in India could serve as a significant precedent for Google's broader global strategy for the RCS standard. Sameer Samat, president of Android ecosystem at Google, reiterated the company's commitment to collaborating with the wider ecosystem of carriers internationally. The goal is to cultivate a consistent and trusted messaging experience for all RCS users around the globe, strongly hinting at the potential expansion of similar deep integrations beyond India to standardize security across the entire RCS framework.

India remains an exceptionally critical market for Google's messaging ambitions, given its expansive digital landscape. The country is home to over a billion internet users and more than 700 million smartphone users. The competitive intensity in mobile messaging is further underscored by India’s substantial WhatsApp user base, which exceeds 853 million, according to World Population Review. Prabhu Ram, vice president for the industry research group at CyberMedia Research, underscored the importance of this deeper carrier integration, viewing it as a vital effort to address longstanding weaknesses in rich messaging ecosystems that have historically been vulnerable to widespread spam and fraud.

Ram further emphasized that the ultimate efficacy of this partnership should be evaluated through tangible metrics. These include measurable reductions in overall spam volume, a decrease in user complaints regarding unsolicited messages, a lower incidence of fraud, and, conversely, an improvement in engagement rates with legitimate business communications. Google has been actively positioning RCS as the modern successor to traditional SMS, having reported in May 2025 that the standard was handling over a billion messages daily in the U.S. based on a 28-day average.

Despite the significance of this development, Google did not disclose whether similar carrier integrations are currently being planned for other international markets. The company also refrained from providing any specific estimates regarding how much this new initiative in India is projected to reduce overall spam and fraud on the platform.
