Availability & rollout
Where RCS is available, how to tell whether it's enabled for your project, and which of your contacts can actually receive it.
RCS is rolling out gradually. Two things decide whether a message goes out as RCS: the country it's available in, and whether each contact's phone can receive it. This page explains both, and where to see your reachable audience.
Where RCS is available
RCS is available through Instasent in Spain currently. France, Italy and Germany are coming next. The list grows country by country.
Is RCS enabled for your project
SMS is always available, and RCS sits alongside it. To begin sending RCS, you first create your sender. Then you register and approve the RCS agent in each country where you want to operate. Until the agent is approved in a country, you can't send RCS messages to that destination. Once the agent is approved, RCS becomes available for that project and that country. See RCS senders & verification to register yours.
Who can receive RCS
A contact receives RCS when their phone and messaging app support it, in a country where your agent is approved. Instasent tracks this per contact, so each one is one of:
- Supported — confirmed able to receive RCS.
- Not supported — confirmed unable; they'll get the SMS fallback instead.
- Unknown — not yet determined.
Supported contacts receive your message as RCS. For Not supported and Unknown contacts, if fallback is enabled, delivery is attempted by SMS, which is billed under the SMS channel's conditions; how each case is charged is detailed in SMS fallback.
See how many contacts are reachable
When you pick the audience for a campaign or automation, the summary shows a Breakdown by RCS support — how many contacts are Supported, Not supported or Unknown — alongside the Available audience for RCS + SMS. This tells you, before you send, how much of your audience RCS will reach directly.
