What is Sinch's RCS Upscale offering?

Sinch’s RCS Upscale solution allows businesses to seamlessly transition from SMS to RCS without additional costs or integration changes. For markets with no reach and devices that aren’t RCS-enabled, we proceed with sending SMS instead guaranteeing messaging reach.

So, it’s RCS when we can and SMS when we can't, ensuring messages are always delivered!

How does it work?

SMS API customers send their SMS request to Sinch as normal, hence no integration changes for existing customers wanting to onboard to our RCS Upscale solution.
Sinch performs an on-net capability check to determine if the country has RCS coverage and whether RCS Upscale is configured. If the answer is yes, we check whether the contact has an RCS-compatible device.
Based on these conditions being met and by performing a capability check upfront, we either send a business message to a customer as RCS (to RCS-enabled devices) or SMS to the rest:
