Telegram and Viber both offer real business-messaging tools- but both require the recipient to have a separate app installed. Here's how RCS, Telegram Business, and Viber Business Messages actually compare on features, pricing, and reach across the Indian market.

RCS (Rich Communication Services)is the modern successor to SMS, built directly into Google Messages on Android. It carries verified-brand messages with images, carousels, suggested replies, and tappable action buttons- inside the customer's default messaging app, with no separate download or opt-in step. For a broader overview of how RCS fits into a business messaging strategy, see our Business Messaging Platform page.
Telegramis a standalone, downloadable messaging app with bots, public channels, and a Business API that verified businesses can use to message users who have started a chat, joined a channel, or interacted with a bot. It's a genuinely capable platform for community-style broadcast, but it requires the recipient to have Telegram installed and to have found and opted into that channel or bot first.
Viber is a similar standalone app, and Viber Business Messageslets verified businesses send transactional and promotional notifications to their existing Viber user base. Like Telegram, it requires the recipient to have the Viber app installed. RCS differs from both in one structural way: it lives inside the phone's default messaging app, so there's no separate app to install or discover before a message can be delivered.
On raw feature capability, the three channels are closer than most comparisons suggest- the real differences show up in reach and install requirements, covered in the sections below.
| Feature | RCS | Telegram / Viber |
|---|---|---|
| Rich Images | ✅ | ✅ |
| Carousels | ✅ | Depends (varies by platform) |
| CTA Buttons | ✅ | ✅ |
| Verified Brand | ✅ (Google) | ✅ (platform-specific verification) |
| Read Receipts | ✅ | ✅ |
| Analytics | ✅ | Varies by platform |
| API Integration | ✅ | ✅ (Telegram Bot API / Viber Business Messages API) |
| Customer Experience | High, default-app reach | High, but requires the recipient to already have the app installed |
| App install required | ❌ | ✅ |
Telegram Business API access and Viber Business Messages are priced per-message or per-session by their respective platforms, and rates vary by region and message type- we won't estimate figures we can't verify. RCS is priced per message through providers like Get Click Media. See our RCS Pricing India page for current rates, and factor in reach- not just per-message cost- when comparing channels for a general customer base.
Rich media isn't a meaningful differentiator between RCS, Telegram, and Viber- all three support images, cards, and buttons within their own app. The factor that actually separates them is reach, covered next.
RCS, Telegram, and Viber all render inline images and structured message cards- visual quality alone isn't what separates these three channels.
RCS and Telegram both support swipeable product carousels; Viber's carousel support varies by message type and account setup, so it's worth checking against your specific integration.
Tappable buttons are standard on RCS, Telegram bots, and Viber Business Messages- friction reduction here is comparable across all three.
Read receipts are available on RCS, Telegram, and Viber alike- none of the three has a meaningful edge on this specific feature.
This is the section that matters most for an India-focused comparison. Telegram and Viber both have real, engaged user bases- but a business messaging through either app only reaches the customers who already use and have installed that specific app, which is a meaningful constraint for broad-reach campaigns in the Indian market.
| Aspect | Telegram / Viber | RCS |
|---|---|---|
| Installed base in India | Real, but meaningfully smaller than WhatsApp or the default Android SMS/RCS messaging app- both platforms have genuine but comparatively niche user bases in the Indian market. | Available by default within Google Messages on a large and growing share of Android devices in India, with no separate app download needed. |
| Reach on a general customer list | Limited to the subset of your customers who already use and have installed the specific app. | Reaches your general customer base without requiring a specific app to already be installed. |
| Where the app does have strength | Both have genuinely engaged, loyal audiences for specific use cases- tech-savvy communities, particular regional or interest groups, and privacy-conscious users. | Strongest for broad-reach campaigns across a general Indian customer base, not limited to a specific sub-audience. |
RCS sits inside Google Messages, the app already on the phone- no install step stands between your message and the customer.
Telegram channels and Viber Business Messages both reach real, often highly engaged audiences- just a smaller slice of the general population in India.
The practical question isn't which app is "better"- it's whether your campaign needs broad reach or a specific, already-engaged community.
General-population messaging penetration in India currently favours SMS/RCS and WhatsApp over Telegram or Viber, though this varies by audience and city.
Telegram has a verified-channel and bot-verification system for businesses, and Viber runs its own business verification process. RCS uses Google's brand verification to confirm sender identity before a message goes out. All three offer a genuine trust signal- the real differentiator between the channels isn't security depth, it's reach and whether the recipient needs a specific app installed to receive the message at all.
Telegram and Viber both offer some level of delivery and engagement reporting through their respective business tools, though the depth varies by platform and account tier. RCS campaigns through Get Click Media's RCS Analytics add read receipts, button-tap tracking, and carousel engagement data in a single dashboard, which is useful if you're already comparing that reporting layer against what Telegram or Viber provide natively.
The Telegram Bot API and Viber's Business Messages API are both mature, well-documented APIs that plenty of businesses integrate against directly. The Get Click Media RCS API follows a comparable request/response pattern for RCS. This isn't really a capability gap between the platforms- it's more a question of which channel's reach and install base fits your audience, which the next section covers directly.
Telegram is a strong fit for community and channel-style broadcast- reaching an audience that has actively chosen to follow a business through a public channel or group, and it tends to skew toward tech-savvy or privacy-conscious users. RCS is a better fit for reaching a business's general existing customer base- order updates and appointment reminders- without requiring that customer to first discover and join a Telegram channel.
| Aspect | Telegram | RCS |
|---|---|---|
| Audience type | Reaches users who have actively found and joined your channel, group, or bot. | Reaches your existing customer base directly, with no discovery or join step required. |
| Best for | Community broadcast to an engaged, opted-in following- announcements, updates, tech-savvy or privacy-conscious audiences. | Order updates, appointment reminders, and other one-to-one communication with customers you already have. |
| Reach requirement | Recipient must have Telegram installed and must have joined the specific channel or bot. | Recipient needs only a default Android messaging app with RCS enabled- no separate discovery step. |
Viber Business Messages is built for the same kind of transactional and promotional notifications RCS is used for- the difference is that it's gated by whether the recipient has the Viber app installed. RCS reaches the same use cases without that install requirement, for the larger share of Android users in India who already have RCS available by default.
| Aspect | Viber | RCS |
|---|---|---|
| Primary use | Transactional and promotional notifications sent to Viber's existing user base. | The same transactional and promotional use cases, without an app-install prerequisite. |
| Reach requirement | Recipient must have the Viber app installed on their device. | Available by default within Google Messages for the large share of Android users in India who already have RCS. |
| Message format | Rich media, buttons, and business verification, similar in capability to RCS. | Comparable rich-media formatting- the practical difference is the install requirement, not the message itself. |

If your business already has a Telegram or Viber following, those channels remain worth keeping for that specific audience. For broad-reach communication across a general Indian customer base, RCS's default-app reach makes it the stronger primary choice. See our Business Messaging Platform page for how RCS fits alongside other channels.

It depends on the goal. For reaching a business's general existing customer base- order updates, reminders, support notifications- RCS has an advantage because it lives inside the phone's default messaging app with no install step. Telegram is strong for community-style broadcast to an audience that has actively chosen to follow a business, which is a different use case.
