RCS Business Messaging (RBM)

RCS Business Messaging (RBM) is the enterprise variant of RCS: brands send verified, branded messages with rich media and interactive elements straight into the phone's native messaging app. Instead of an anonymous number, recipients see a name, logo, and a trust checkmark. It replaces plain bulk SMS with branded, interactive conversations.

What is RCS Business Messaging (RBM)?

RCS Business Messaging, or RBM, is the application-to-person (A2P) branch of RCS: businesses use it to send messages to customers directly in the pre-installed messaging app ("Google Messages" on Android). Unlike classic SMS, the recipient sees more than text from a number; they see a verified, branded sender with logo, brand colours, and a trust checkmark. RBM turns plain SMS sending into a branded, interactive conversation.

Features of RBM

RBM bundles several capabilities SMS does not offer:

  • Verified sender: a vetted brand name, logo, and checkmark instead of an anonymous number.
  • Rich cards and carousels: image, title, text, and buttons in one card, multiple cards as a horizontally scrollable carousel.
  • Suggested replies and actions: tappable buttons for replies, links, calls, location, or calendar entries.
  • Read receipts and typing indicator: the sender sees whether a message was delivered and read.
  • Rich media: images, short videos, and files directly in the chat.

Positioning vs. SMS and WhatsApp, requirements

RBM sits functionally between SMS and messenger apps: like SMS it uses the native app with no extra download, but it offers rich media and interaction like a modern messenger. Sending requires agent registration and brand verification, usually handled through an aggregator; once approved, the branded sender goes live. Reach in Germany: RCS today reaches around 70 million people, according to the four German carriers. iPhones are reachable since iOS 18 (late 2024), where the mobile carrier supports RCS; a conversation between an iPhone and Android still stays a green bubble. Technically, RBM messages are transport-encrypted to industry standard (TLS 1.3) between the device and Google's RBM platform, but not end-to-end encrypted. Where RCS is unavailable, an SMS fallback typically takes over.

RBM and SendSeven
