How is a carousel parsed for SMS?

We convert carousels to text bullet points, appending custom short links pointing to a web display.

Can we define the fallback timeout?

Yes. The default fallback check window is 30 seconds, which can be modified in API headers.

What is RCS (Rich Communication Services) and how does it work?

RCS is the modern successor to traditional SMS developed by Google and MNOs for Android smartphones, enabling brands to send interactive, rich content directly inside native text messaging boxes.

What is the main commercial difference between RCS and traditional SMS marketing?

RCS supports rich colored logos, verified business profiles, carousel cards, videos, and dynamic call-to-action buttons, yielding click-through rates (CTR) up to 4 times higher.

Does RCS require end-users to install secondary messaging applications on Android?

No. RCS runs natively inside the pre-installed Google Messages inbox on almost 90% of active Android devices in Brazil.

How does the brand registration and verified profile process work for RCS?

Our operations team coordinates the approval of your corporate sender profile directly with Google and Brazilian carriers, activating your official verified business badge securely.

What dynamic action buttons are supported inside RCS cards?

RCS supports native dynamic buttons that allow users to click to open a secure HTTPS URL, dial support phone lines, load GPS maps, or write calendar reminders.

Does RCS support rich product carousel cards?

Yes. You can send rich carousels containing up to 10 image cards complete with dynamic descriptions, offer prices, and individual purchase triggers.

Does RCS provide read receipts for transmitted messages?

Yes. Unlike legacy SMS where we only track carrier delivery, RCS provides explicit read receipts (Read Receipts) alongside click-through indicators on buttons.

How is RCS pricing structured in the Brazilian market?

Carriers bill RCS per 24-hour conversational session divided into two main categories: Basic Text (Utility) and Rich Media (Promo). Contact our sales team for volume estimates.

RCS to SMS Smart Fallback

Why is automated RCS-to-SMS fallback critical?

RCS is active on Android, but some users may be offline or on devices without RCS capability. Our systems check network status and switch delivery to SMS text within seconds.

This keeps your transactional pipeline 100% reliable without adding routing complexity to your backend application.
