Google is taking a new approach to India's messaging spam crisis. The company just announced a partnership with telecom giant Airtel to embed carrier-level filtering directly into Rich Communication Services (RCS), marking the first time the search giant has teamed up with a carrier to fight spam before it reaches users' phones. The move signals Google's growing urgency to clean up RCS as it positions the protocol as the successor to SMS.
Google is finally addressing one of RCS's biggest problems in one of its most important markets. The company announced it's working with Airtel, India's second-largest telecom operator with over 350 million subscribers, to build spam filtering directly into the carrier's RCS infrastructure. Instead of relying solely on device-level blocking in Google Messages, the new system catches spam at the network level before it ever reaches users.
The partnership represents a shift in Google's spam-fighting strategy. Until now, the company has relied on on-device machine learning to identify and block suspicious messages - a reactive approach that still lets spam consume bandwidth and processing power. By filtering at the carrier level, Google and Airtel can stop malicious traffic before it propagates through the network, potentially saving millions in infrastructure costs while protecting users more effectively.
India makes for the perfect testing ground. The country has struggled with rampant SMS and messaging spam for years, with scammers exploiting cheap bulk messaging services to flood users with everything from fake loan offers to phishing attempts. According to industry estimates, Indians receive an average of 3-4 spam messages daily, significantly higher than most Western markets. As RCS adoption grows - Google doesn't disclose exact numbers, but Messages has over 1 billion users globally - spammers have begun migrating to the richer protocol.
The timing isn't coincidental. Google has spent years pushing RCS as the modern replacement for SMS, complete with read receipts, typing indicators, and high-quality media sharing. But spam threatens to undermine that vision. If users associate RCS with the same garbage that plagued SMS, they're less likely to embrace the upgrade. Worse, it gives ammunition to , which has resisted adopting RCS for iMessage, citing security and spam concerns.
