What Is RCS

SMS Upgraded — No App Required

RCS Business Messaging (RBM) is the carrier-backed successor to SMS, delivering rich interactive experiences through the device's native messaging client. MOBITELSMS connects to Google RBM and multiple GSMA-accredited aggregators, giving your messages the broadest possible reach with automatic SMS fallback for non-RCS handsets.

Features

Rich Messaging Capabilities

Rich Cards & Carousels
Send standalone rich cards or horizontal carousels containing images, titles, descriptions, and action buttons. Ideal for product showcases, appointment confirmations, and promotional campaigns.
Suggested Actions
Embed reply chips, dial-number buttons, open-URL actions, and share-location prompts directly in messages. Recipients interact with one tap — no typing required, maximising conversion rates.
Verified Sender Identity
GSMA-verified brand profile with your logo, brand color, and description displayed in the messaging thread. Recipients see who they are talking to before reading — combating SMS fraud and spoofing.
Read Receipts & Typing
Full ISRM (Is-Composing) and read-receipt notifications give real-time insight into message engagement. Delivery and read events feed directly into your campaign analytics dashboard.
Automatic SMS Fallback
The platform detects RCS capability per MSISDN in real time. Non-RCS handsets automatically receive an SMS fallback version, ensuring 100% audience reach without duplicate campaign management.
HMAC Webhook Security
All inbound RCS events (replies, delivery receipts, user actions) are delivered to your webhook endpoint with HMAC-SHA256 signature verification, preventing spoofed event injection.
