Why is fallback necessary for RCS campaigns?

RCS depends on device compatibility (Android with Google Messages) and carrier support. Since some users may be on iOS (until full RCS rollout), older handsets, or out of internet coverage, a fallback channel like transactional SMS is critical to ensure important alerts are never lost.

How does Textspeed check RCS capability?

Our platform performs a real-time lookup against Google's RCS capability directory before dispatching the message, determining within milliseconds whether to route the RCS rich payload or trigger the SMS fallback template.

Do I need to write two separate messages for every campaign?

Yes. Through our API or dashboard, you define the rich RCS content (images, buttons, carousels) and the plain SMS fallback text version. This ensures that the SMS version reads naturally rather than as a broken rich payload.

Is SMS fallback DLT compliant in India?

Yes. Textspeed's fallback router is DLT-aware. When a message downgrades to SMS, it routes through your pre-registered DLT templates and headers automatically to ensure compliance with TRAI regulations.

What is RCS Fallback

Rich Media Delivery Without the Channel Risk

RCS (Rich Communication Services) lets you send branded, interactive messages — images, carousels, buttons, quick replies — instead of plain text. The catch: RCS only works when both the recipient's device and carrier support it. Everyone else needs to get the message some other way, or they get nothing.

RCS Fallback solves this at the platform level. You send one message. TextSpeed checks device and carrier RCS capability in real time — if RCS is supported, it delivers the rich experience; if not, it automatically falls back to a plain SMS template with the same core content, so the message always reaches the customer.

Key Features

Everything You Need for Resilient Rich Messaging

A single integration that balances premium visual design with absolute delivery assurance.

Automatic, Real-Time Fallback

Capability is checked per recipient at send time — no manual list segmentation, no guesswork. RCS-capable numbers get rich messages; everyone else gets SMS instantly.

Rich RCS Experiences

Send carousels, suggested replies, action buttons, images, and branded sender profiles — a native app-like experience inside the messaging thread.

Guaranteed Reach

Every message either lands as RCS or falls back to SMS — never silently dropped because a device isn't RCS-capable.

One API, Two Channels

A single API call handles both RCS and SMS delivery logic. No separate integration, no separate vendor for the fallback channel.

Unified Delivery Reporting

See exactly which messages delivered as RCS vs. fell back to SMS, per campaign, in one dashboard.

Configurable Fallback Content

Define your rich RCS message and a matching SMS fallback text independently, so the SMS version reads naturally rather than as a broken RCS payload.

DLT Compliant Fallback

SMS fallback messages route through your DLT-registered templates automatically — no compliance gaps when a message downgrades channel.

Built to Scale

Send to a handful of numbers or millions — capability checks and fallback routing happen transparently at any volume.

Common Use Cases

Seamless Fallback Across Every Scenario

Define your rich content layout and text fallback content once. The router handles the rest dynamically.
