Infobip RCS vs SimplyRCS, Compared (2026)

Infobip sells RCS as one channel inside a much larger omnichannel suite. You reach it through the same Messages API that carries Infobip's SMS, WhatsApp, Viber, and email traffic, or through Moments if you want campaigns built in a visual tool rather than in code. Rich cards, carousels, and suggested actions are all supported, and Infobip handles Google RBM agent verification as part of enterprise onboarding.

Where Infobip RCS is genuinely strong

Reach is the real product. Infobip holds direct operator connections across sixty-plus countries, so if your audience spans several markets, one contract and one API cover all of them. The enterprise tooling around the channel is mature too: Conversations for agent-handled threads, Moments for orchestration, and a CDP underneath if you need one. For a global enterprise, that consolidation is worth a great deal.

Where it gets expensive or slow

Infobip does not publish RCS pricing. Every rate is a custom quote, which means the number depends on your volume, your markets, and your negotiating position rather than on a rate card you can check. Its AgentOS pricing also lists a processing fee starting at about $0.075 per outbound interaction, charged on top of a $530 a month platform fee and the message cost. On a 100,000-message campaign that surcharge alone can run into thousands, and it is the line most people miss when they compare a quoted per-message rate against a published one.

Onboarding is an enterprise process rather than a signup, and support terms are set by contract rather than published. Neither is unusual at that scale, but both matter if you are a US team that wants to be live in weeks.

What Infobip says about carrier fees

Very little, and that is the finding. US carriers levy their own per-message surcharges on A2P traffic, and those fees are real money at volume: on a 50,000-message month they are the second largest line on our own invoice after the messages themselves. Whether a provider passes them through at cost, marks them up, or blends them into a headline rate changes the total substantially.

Infobip's public RCS pricing page does not state which of those it does. The only statement it makes on the subject is that "local operator agreements set the base cost", which describes where the cost originates rather than how it reaches your bill. Combined with there being no published per-message rate at all, that means the carrier component of an Infobip quote cannot be checked from outside.

So ask for it explicitly, and ask in these terms: are US carrier surcharges passed through at cost or marked up, do they appear as their own line on the invoice or inside the per-message rate, and which carriers' fees are included in the quoted number. A quote that answers all three is comparable to a published rate card. One that does not is a single number you cannot decompose.

Our own answer is on the billing transparency page: carrier surcharges are passed through at cost, on their own invoice line, with no markup, and the sample bill shows them itemised against a 50,000-message month.

How SimplyRCS differs on the same channel

The RCS itself is the same standard, the same verified sender, the same rich cards in the same Google Messages inbox. What differs is everything around it. SimplyRCS is US-only and publishes every rate on the pricing page, charges no per-interaction fee, includes the campaign builder and shared inbox rather than licensing them as enterprise modules, and prepares and files your brand, campaign, and RCS agent registrations for you. If you need Jakarta and Lagos, Infobip is the answer. If you need AT&T, Verizon, T-Mobile, and a bill you can predict, this is.

Infobip exposes RCS as one channel inside its omnichannel messaging API, alongside SMS, WhatsApp, email and voice, and the same suite carries Moments for campaigns and Answers for chatbots. The API is broad and global; access, pricing and onboarding are enterprise: quote-priced, contracted, with a per-interaction processing fee reported on Moments. The SimplyRCS API is narrower on purpose. It covers RCS, SMS and MMS for US carriers from one verified sender, with a public OpenAPI reference, self-serve keys, published per-message rates and no per-interaction fee, and it is the same interface the app uses. Choose Infobip's API when the programme spans many countries and channels under one contract; choose SimplyRCS's when it is a US programme that needs to start this month on a rate card you can read.
