How does Kero decide which channel to use?

Kero checks the recipient's device capabilities in real time. If the device supports RCS, the message sends via RCS. If not, Kero checks for WhatsApp. If neither is available, the message delivers via SMS. This happens automatically with one API call. You don't need to build any routing logic.

What does SMS messaging cost through Kero?

SMS pricing varies by country and volume. Kero bundles SMS with RCS and WhatsApp in a single platform plan with flexible volume tiers to suit businesses of all sizes. You get all three channels with one billing relationship. Contact us for pricing specific to your region.

Which countries does Kero support for SMS?

Kero has 1,500+ global SMS connections across Africa, Europe, the Middle East, and beyond. SMS delivery is available anywhere with mobile network coverage. Contact us for the full list of supported countries and carrier routes.

Can I send SMS without using RCS or WhatsApp?

Yes. While Kero's intelligent routing tries rich channels first, you can configure SMS-only campaigns for use cases where plain text is preferred, like OTP codes, appointment reminders, or compliance notifications. You control the routing rules per campaign.

How do I integrate SMS into my existing systems?

Kero provides a single JSON API that handles SMS, RCS, and WhatsApp. One integration covers all three channels. The API includes webhooks for delivery status, full documentation, and hands-on support from the Kero team.

SMS Messaging

Every Message Delivered, Every Device Reached

SMS is the universal messaging channel that reaches every mobile device on the planet. Use it as a standalone channel for direct campaigns, OTPs, and alerts — or as the intelligent fallback that guarantees delivery when RCS and WhatsApp aren't available.

The Challenge

Rich Channels Don't Reach Everyone

RCS and WhatsApp cover most of your audience, but gaps remain. Without a reliable fallback, some customers never receive your message.

Device Compatibility Gaps

Not all phones support RCS. Not all users have WhatsApp installed. Without SMS fallback, these customers simply never receive your message.

Silent Delivery Failures

Sending via a single channel means some messages disappear with no notification. You think the message was sent. The customer never sees it.

Fragmented Multi-Channel Setup

Managing separate SMS providers alongside RCS and WhatsApp means three dashboards, three APIs, and three billing systems. Operational overhead adds up fast.

Intelligent Routing in Three Steps

Kero handles channel selection automatically. Every message finds the best path to delivery.

Step 1

Message Sent

Compose your message once in Kero. The platform selects the best channel — RCS, WhatsApp, or SMS — based on device capabilities.

Step 2

Message Delivered

Kero confirms delivery to the recipient's device with real-time status updates. If the primary channel fails, automatic fallback ensures the message reaches its target.

Step 3

Message Read

Track read receipts and engagement across all channels in one unified dashboard. Know exactly when customers see and interact with your messages.

SMS Messaging FAQ

Common questions about SMS delivery through Kero.

RCS and WhatsApp don't reach every device. Some phones don't support RCS, and not all users have WhatsApp installed. SMS is the universal fallback that works on every mobile phone in every country. With Kero, your message tries the richest channel first and falls back to SMS only when needed, so you get the best experience possible with guaranteed delivery.
