Google RCS spam has once again moved to the center of India’s messaging debate — and this time, Google is responding with a deeper telecom-level integration.

As persistent spam complaints continue to shadow Google’s Rich Communication Services (RCS) rollout in India, the company is tightening its approach. On Sunday, Bharti Airtel announced a new integration with Google that brings the carrier’s network-level spam filtering directly into the RCS ecosystem.

The move signals a more defensive and infrastructure-driven strategy as Google works to stabilize user trust in one of its most ambitious messaging bets.

Google RCS Spam Triggers Airtel Integration Move

Bharti Airtel, India’s second-largest telecom operator with more than 463 million subscribers, said it has partnered with Google to embed its spam filtering systems into RCS traffic within the country.

The aim is straightforward: strengthen protections against unwanted messages and fraud on the platform.

India has proven to be one of the toughest markets globally when it comes to messaging spam. The scale of the country’s mobile user base, rapid digital payments adoption, and aggressive enterprise marketing have created a challenging environment for any messaging platform.

Back in 2022, complaints about unsolicited ads delivered through Google’s RCS — primarily via the Google Messages app — became significant enough for Google to temporarily pause business promotions on the platform in India. While that step addressed immediate concerns, user frustration over spam on Google Messages has continued to surface.

Airtel made it clear that it had previously held back from deeper RCS alignment until stronger routing controls were in place.

“We had not onboarded Google because we first wanted RCS messages to be routed through the Airtel spam filter,” an Airtel spokesperson said.

Under what many are describing as an Airtel Google RCS spam filter partnership, the carrier’s network intelligence will now work alongside Google’s RCS platform to enable real-time checks on business messaging. That includes sender verification, spam detection, and enforcement of users’ do-not-disturb preferences.

Airtel called the integration a “global first” for combining telecom-level spam filtering directly into an over-the-top messaging platform, though no comparative examples were shared.

Sameer Samat, president of Android ecosystem at Google, said the company is committed to working with carriers globally to create a consistent and trusted messaging experience for RCS users. The statement suggests that similar models could be explored beyond India.

India’s Messaging Battlefield and RCS vs WhatsApp India messaging

India is critical to Google’s messaging ambitions. The country has more than a billion internet users and over 700 million smartphone users. At the same time, competition remains intense.

According to World Population Review, WhatsApp has more than 853 million users in India. That scale highlights the ongoing RCS vs WhatsApp India messaging comparison that continues to shape the broader ecosystem.

Industry analysts say the deeper carrier integration reflects efforts to address longstanding weaknesses in rich messaging systems.

Prabhu Ram, vice president for the industry research group at CyberMedia Research, told TechCrunch that the effectiveness of this partnership should be measured through tangible outcomes — such as reductions in spam volume, fewer user complaints, lower fraud incidence, and improved engagement with legitimate messages.

Over the past year, Airtel has stepped up its anti-spam efforts. The company says its AI-led systems have blocked more than 71 billion spam calls and 2.9 billion spam messages. According to Airtel, this has contributed to nearly a 69% drop in fraud-related financial losses on its network.

More broadly, Google has positioned RCS as the successor to SMS. In May 2025, the company said the standard was handling more than a billion messages daily in the U.S., based on a 28-day average.

What remains unclear is whether similar carrier-level integrations will be deployed in other markets, or how much measurable impact the current partnership could have on reducing spam and fraud in India.

For now, the Airtel integration represents a significant attempt to address user trust — and to ensure RCS can scale in one of the world’s most competitive messaging environments.
