If you’ve recently enabled Rich Communication Services (RCS) on Google Messages and noticed a sudden flood of promotional and scam messages, you’re not alone. The rise of RCS spam in India has frustrated thousands of users who expected a smarter, more secure texting experience but ended up drowning in unsolicited stock tips and brand offers. While RCS is meant to be the next generation of SMS, in India it has exposed a deep problem—one that reflects poor privacy enforcement and lackluster spam protection.
What is RCS, and Why Did It Backfire in India?
RCS is Google’s modern take on SMS, offering features like typing indicators, read receipts, rich media sharing, and end-to-end encryption for chats. It’s meant to compete with WhatsApp and iMessage, giving Android users a better built-in texting experience.
However, after enabling RCS, many Indian users—including myself—began to notice something odd: a steady increase in spam messages. These weren’t just promotional messages from brands we’d interacted with in the past. There were also shady stock market tipsters and companies we’d never heard of.
The most frustrating part? Even when you try to unsubscribe using the built-in “STOP” command, it often responds saying you’re opted out, only for the same brand to message you again—this time using a different sender ID. This tactic creates an endless loop of spam you can’t really opt out of.
Why Is RCS Spam in India So Common?
A Possible Loophole in Digital Privacy Laws
While it’s hard to pin down a single reason, a lack of strict data protection laws in India may be a major contributor. Unlike regions like the EU (with GDPR) or California (with CCPA), India is still in the process of rolling out comprehensive data privacy legislation. This gives marketers, data brokers, and even scammers a more lenient playing field.
Moreover, RCS’s spam protection is vague and underdeveloped in Google Messages. Despite having options to “block & report” senders, the system often fails to recognize or restrict patterns of spam when it’s sent using alternate sender IDs.
Another key issue is the abuse of verified business messaging, where legitimate companies use RCS to push promotions without strong consent mechanisms. The lack of a centralized and transparent opt-out registry makes it worse.
How Other Countries Compare
Interestingly, Reddit discussions show that RCS users in countries like the US or Germany don’t face this level of spam. This suggests the issue isn’t with RCS as a technology—but with how it’s being used (or misused) in India. Loose regulatory oversight combined with aggressive marketing practices is likely the real culprit.
Google has not provided a clear roadmap or solution for Indian users beyond suggesting individual blocks—which don’t work when spammers simply rotate sender names.
What Can You Do?
- Disable RCS chats if you’re overwhelmed with spam (Settings → Chat features → Turn off RCS chats).
- Block individual senders, though this is a cat-and-mouse game.
- Use alternative apps like WhatsApp or Signal for critical conversations.
- Raise awareness by reporting the issue on forums like Reddit or tagging Google on social media.
If you’re running a tech blog or writing about digital privacy in India, this is a growing area of concern worth documenting.

RCS was supposed to be the future of messaging—but in India, it’s quickly becoming a nightmare for users who value their privacy. Until there’s stronger spam regulation and better user controls, RCS spam in India will continue to worsen. For now, disabling the feature might be your only way out.
🚫 Why TRAI Can’t Control RCS Spam Easily
1. RCS Operates Outside Telecom Regulatory Boundaries
RCS messages are sent over the internet (via mobile data or Wi-Fi), not via traditional SMS gateways that go through telecom operators. That makes it harder for TRAI to regulate, because:
- TRAI’s rules (like the Telecom Commercial Communications Customer Preference Regulations, 2018) apply to telecom operators and SMS routes — not internet-based platforms like Google Messages using RCS.
- RCS is technically a form of OTT (Over-the-top) messaging, like WhatsApp, so it’s not bound by the same spam filtering protocols telecoms must follow.
2. No Universal Sender ID Verification for RCS
TRAI mandates registered sender IDs and template approvals for SMS promotions. But Google Messages’ RCS platform doesn’t follow TRAI’s strict template-checking system, so brands and scammers can just rotate sender names to bypass filters.
3. Lack of Reporting/Blocking Integration
The TRAI DND app is tightly integrated with carrier SMS logs. But with RCS, especially Google-controlled RCS, there’s no unified or enforced reporting mechanism connected to TRAI systems. You can report in Google Messages — but it goes to Google, not TRAI.
🧩 So, What Can Be Done?
- Google must introduce India-specific spam control that aligns with existing DND guidelines — e.g., block repeated unsolicited business messages from verified brands.
- A central opt-out system for RCS promotions (similar to DND registry) could help.
TRAI curbed SMS spam by regulating telecoms. But RCS runs on internet protocols, not telecom SMS channels, so TRAI has no direct control over it — yet. The ball is now in Google’s court…
