Which RCS provider has the most transparent pricing?

A rate card is transparent when the invoice can be predicted from it. That is a higher bar than publishing a number, because the per-message rate is usually the smallest of the surprises. The scorecard below marks each provider on the five layers of a US messaging bill, using only what each one has put in writing, and says so where a number is missing rather than guessing one. Figures were verified in September 2026 against each vendor's published pricing or documentation; quote-priced vendors change terms by contract, so confirm with them directly.

What transparent pricing has to include

Seven things decide what a US RCS programme costs over its life. A provider is transparent to the extent it publishes all seven.

1. Per-message rates, by class. The text rate and the media rate separately, whether an interactive card with buttons bills as text or as media, and whether text bills per message or per 160-character segment. A long message that is one RCS message can be three SMS segments.
2. Carrier fees. Verizon, AT&T, T-Mobile and US Cellular each levy a per-message surcharge on business traffic. The question is whether the provider publishes them, passes them through at cost on their own line, or blends them into a headline rate.
3. Setup and sender fees. Agent or sender activation, annual vetting, and what it costs to change a sender profile you already paid to create.
4. Numbers and registry fees. Monthly number rental, 10DLC brand and campaign fees from The Campaign Registry, and who files them.
5. The penalty lines. Failed-message charges, per-interaction processing fees, support tiers and separately licensed AI products. Infobip publishes $0.07456 per outbound AI interaction on its AgentOS plan; Twilio publishes production support from $250 a month or 4 percent of spend; on SimplyRCS email support is free, Premium Support is optional at $250 a month, and AI usage is an optional package priced separately.
6. Onboarding and porting costs. What it costs to move in: number porting, re-filing 10DLC and the verified RCS agent, and running in parallel with the old provider. Long codes and toll-free numbers carry no carrier migration fee anywhere; short codes carry carrier-set fees ($500 T-Mobile, $250 Verizon, $150 Claro) that should be passed through at cost. Ask whether the provider itself charges for any of the three; SimplyRCS does not, and moving from Twilio without losing your numbers has the checklist.
7. Contract fine print. Term, minimum monthly commitment, notice period, auto-renewal, overage rates above a plan tier, and what happens to the rate when volume falls. Pay-as-you-go providers have none of these; plan-tier and enterprise providers have all of them, and they belong in the comparison because they decide what you pay in a slow month and what it costs to leave. SimplyRCS has no contract, minimum or term.

The scorecard

Three tiers fall out of that table. SimplyRCS and Plivo publish rate cards, and SimplyRCS also publishes the carrier fees and the setup fees around them. Twilio, Vonage and Bandwidth publish part of the picture: rates without surcharges, a billing model without rates, or a fee structure without a price. Sinch, Infobip and Bird price by quote, so the only way to compare them is to get the quote first.

Why the per-message rate is the least of it

On a real invoice the per-message line is often not the largest one. On the billing transparency page, the illustrative 50,000-message month shows $195 in message charges next to $261.30 in carrier pass-through surcharges, and that is with the surcharges at cost. A provider that marks those fees up, or folds them into a blended rate, can quote a lower headline number and deliver a higher total, and there is no way to tell from the outside unless the fees are published.

The same is true of message classes. Twilio's $0.0083 is the rate for basic RCS, which is text. The rich cards, carousels and suggested actions that are the reason to use RCS bill at the rich class, about $0.0220. SimplyRCS follows the carriers' US model: text with reply buttons is the text rate and any card, carousel or media is the media rate. Either way, the published rate you compare has to be the one for the format you will actually send. How much does RCS cost walks through each component.

Transparent is not the same as cheapest

The two published rate cards are shaped differently, and honesty about that is part of being transparent. Neither charges a monthly platform or agent fee, so the comparison comes down to the per-message rates. On rich text SimplyRCS is $0.0039 a segment, against $0.0077 per segment at Plivo. On rich media it is $0.0150, against $0.0180. So SimplyRCS's published rates are lower at every volume. Cheapest is still a separate test from transparent: carrier surcharges, registry fees and one-time sender setup belong in any total, and the rates side by side are on SimplyRCS vs Plivo. Which RCS providers charge no platform fee lists the usage-only providers and what each still charges per verified sender.

What the rate cards leave out is the work around the messages: the campaign builder, the shared inbox, the bot builder, support, and the team that files your carrier registrations. On SimplyRCS the software is free, email support is free on every account, and we file the registrations; Premium Support adds a dedicated account manager for $250 a month if you want one. On a developer-first platform that tooling is yours to build and maintain, and it appears on nobody's rate card.

How to check a quote you cannot see

If the provider you are evaluating is one of the quoting six, the quote becomes comparable to a published rate card only when it answers the same five questions. Ask for the text rate and the media rate separately, and whether text bills per segment or per message. Ask whether US carrier surcharges are passed through at cost or marked up, whether they appear on their own invoice line, and which carriers' fees the quoted number includes. Ask for the activation fee, the annual vetting fee and the cost to change a sender profile. Ask what a number costs a month and who files 10DLC. And ask what is billed on a failed message, on a support ticket, and on the AI product. A quote that answers all of them can be compared. One that does not is a single number you cannot decompose. Questions to ask an RCS vendor has the full list.

A ten-line audit you can run on any vendor

Score a provider one point per "yes", from its public pages alone, before the first sales call. Seven or more and the invoice can be predicted; four or fewer and you are buying a quote, not a rate card.

1. Is the US RCS text rate published?
2. Is the US RCS media rate published separately from the text rate?
3. Does the page say whether an interactive card without media bills as text or as media, and whether text bills per message or per segment?
4. Are US carrier surcharges published per carrier and passed through at cost on their own invoice line?
5. Are the one-time sender setup fee and the annual vetting fee published, with the cost of changing a sender profile?
6. Are number rental and the Campaign Registry fees listed?
7. Is any recurring charge that exists whether or not you send named and priced per sender?
8. Are failed-message, support and AI charges either published or stated to be included?
9. Are porting, re-filing and parallel-run charges either published or stated to be none?
10. Is there no term, minimum or notice period, or are all three published?

How SimplyRCS answers each line

Two things this page does not carry, on purpose. There are no screenshots of competitor pricing pages, because those pages change and a stale image misleads; every figure above links to the live page it came from and carries its check date. And there is no customer quote, because SimplyRCS does not publish testimonials it cannot attribute; the sample invoice on the billing transparency page is the evidence of cost predictability, line by line.

Where SimplyRCS sits

SimplyRCS publishes every layer on the pricing page: $0.0039 per SMS or RCS text segment, $0.0150 per MMS or RCS card or media message, the same rate inbound and outbound; $0.0004 per RCS device check and optional conversation pricing at $0.05 per 24-hour conversation; the per-carrier surcharge table at cost; no monthly platform or agent fee, with the app, API, bots, inbox and analytics free and email support on every account; the one-time $250 RCS Sender ID setup and review, $200 a year Aegis sender review and $500 T-Mobile activation itemised up front; optional Premium Support at $250 a month, with no setup fee and RCS Sender ID setup and review waived; numbers from $0.50 a month; the Campaign Registry fee schedule; and nothing to change a sender profile. Taxes and surcharges are estimated before checkout and reconciled on the invoice, and the billing transparency page shows a sample bill line by line. That is the standard we would hold any provider to, including us.
