Key features

Everything you need to run RCS at scale.

Verified sender

Your brand name, logo and verified badge appear on every message.

Rich cards & carousels

Show products, offers and tickets with images and descriptions.

Suggested replies & actions

Add buttons to buy, call, open a link or add an event to the calendar.

Read receipts

See when a customer has read your message, not just received it.

Automatic SMS fallback

Devices without RCS receive the message as SMS automatically.

Campaign analytics

Track deliveries, reads and button clicks for every campaign.

How it works

Go live in three simple steps.

  1. Create your RCS agent

    Share your brand name, logo, colours and description. We handle the verification and approval process.

  2. Design your message

    Build rich cards and carousels in the dashboard or send them through the API.

  3. Launch with fallback

    Send to your audience. Non-RCS devices receive SMS automatically.

What is RCS Business Messaging?

RCS (Rich Communication Services) is the upgrade to SMS on Android. It lets businesses send branded, verified messages with images, carousels and interactive buttons.

What happens if a customer's phone does not support RCS?

TalkNest automatically sends the message as SMS, so every customer still receives it.

How long does RCS agent approval take?

Approval timelines depend on the verification process. Our team prepares your brand details to make approval as smooth as possible.

Can I track RCS campaign results?

Yes. You get delivery, read and click reports per message and per campaign.
