RCS business messaging in India: what it is and how it compares to WhatsApp

Updated 2026-09-19 · 4 min read · By the Convo360 team

What RCS actually is

RCS (Rich Communication Services) is a messaging standard that upgrades plain old SMS into something closer to a modern chat app: read receipts, typing indicators, rich media, suggested reply buttons and branded sender cards, all inside a phone's default Messages app, with no separate app to install. Google has pushed RCS heavily through Android's Messages app; Apple has also added RCS support on iPhone in recent years for person-to-person messaging.

For businesses, this means a message can arrive looking closer to a WhatsApp-style card than a plain grey SMS bubble, without asking the customer to install anything new or accept a fresh set of app permissions.

Technically, RCS business messaging is delivered through the phone's carrier network and Google's Messages infrastructure rather than over the open internet the way WhatsApp is, which is part of why its rollout depends so heavily on individual carriers switching it on in a given country or circle, rather than a single global company deciding when it is available.

How it compares to WhatsApp in India

The core difference is reach. WhatsApp is already installed on the overwhelming majority of Indian smartphones across every brand and carrier, and customers have already granted it the permissions and trust that come with years of daily personal use. RCS business messaging depends on the customer's Android phone, their Messages app being set as default, and their carrier having enabled RCS, a combination that, while growing, is not yet as consistent across India as WhatsApp's simple install-once reach.

Feature-for-feature, RCS's rich cards and buttons are conceptually similar to WhatsApp's carousel and button templates, which is why many businesses treat RCS as a complementary SMS upgrade rather than a WhatsApp replacement, at least for now.

Where RCS could fit for an Indian business

• Sending richer order confirmations or delivery updates to customers who don't have WhatsApp, as a step up from plain SMS rather than a full replacement channel.
• Reaching Android users specifically for time-sensitive alerts where SMS is already the fallback channel today.
• Complementing, not replacing, a WhatsApp-first support and sales strategy, especially for businesses that already send a lot of transactional SMS.
• Banks, NBFCs and logistics companies with very high SMS volumes, where even a partial shift of SMS traffic to a richer RCS card could improve how customers understand and act on the message.

Because adoption in India is still uneven across carriers and devices, RCS today is best thought of as a channel to watch and plan for, not the one to build your primary customer communication strategy around just yet. A business that already sends thousands of transactional SMS a month is well placed to benefit early once RCS coverage broadens, since the underlying customer list and message content mostly carry over.

A simple comparison

What Convo360 supports today, and what's coming

Convo360 currently supports WhatsApp Business (Meta Cloud API), Instagram DMs, Facebook Messenger, Telegram, website chat widget, SMS (via Plivo) and Email, all manageable through the same Flow Builder and omnichannel inbox. RCS is on the roadmap — when it ships, it will plug into the same flow structure so you won't need to rebuild anything you've already built for WhatsApp or SMS.

Until then, the practical move for most Indian businesses is to build your automation on WhatsApp first, since it already covers the largest share of your customers, and layer in SMS via Plivo for the fallback cases RCS is aiming to solve down the line.

How to prepare now

1. Get your WhatsApp Business API connected and templates approved — see our WhatsApp API setup guide.
2. Use SMS (via Plivo) as your fallback channel for customers without WhatsApp today.
3. Design your message content (order updates, reminders) in a channel-neutral way, clear, short and action-oriented, so it ports easily to RCS later without a rewrite.
4. Keep an eye on Convo360's channel updates for RCS availability, since your existing flow logic will carry over once it ships.

Mistakes to avoid while RCS is still emerging

Do not delay setting up WhatsApp automation while waiting for RCS to mature — that trade-off costs you reach today for a channel that isn't uniformly available yet. Equally, do not assume RCS will simply replace SMS overnight; carrier rollout and device support both need to catch up first. The safest approach is to treat RCS as additive: something you will switch on for the Android-and-carrier-supported slice of your audience once it is available on Convo360, without disrupting the WhatsApp and SMS automation you already rely on.

Another mistake is assuming RCS availability is purely a software question. Even after Convo360 supports it, an individual customer will only receive an RCS-rich message if their specific carrier and device combination supports it — otherwise the same message typically falls back to a plain SMS automatically, which is why keeping your SMS fallback well-maintained still matters even after RCS becomes available.
