How does SMS fallback work?

Not all recipients can receive RCS messages. Some use older devices, have no data plan, or their mobile carrier doesn't support RCS yet. With our SMS fallback, you still reach everyone.

  • Automatic detection of the recipient's RCS capability
  • Seamless switch to SMS without delay
  • Configurable fallback message for optimal SMS length
  • Transparent reporting shows RCS vs. SMS delivery
Benefits

Why SMS fallback matters

RCS is the future, but SMS is still indispensable today. With SMS fallback, you get the best of both worlds.

100% Reach

Reach every recipient, regardless of their device or mobile carrier.

No manual effort

The system automatically detects who supports RCS and who doesn't. You don't have to do anything.

Cost efficient

Pay RCS prices for RCS recipients and SMS prices for SMS fallback.

Real-time decision

The fallback decision is made in real time, without delaying delivery.

Transparent reporting

See exactly which messages were delivered via RCS and which via SMS.

Future-proof

The more RCS grows, the less SMS fallback you'll need. But you're already ready today.

Use cases

When is SMS fallback activated?

SMS fallback is triggered automatically when the recipient cannot receive RCS messages. This can happen for various reasons:

  • Older devices without RCS support (feature phones, older smartphones)
  • No data plan or no internet connection on the recipient's device
  • Mobile carrier doesn't yet support RCS in certain regions
  • RCS disabled by the user in their settings
  • Roaming abroad without RCS support
