Where each one is the right call.
Weigh both sides. The bar shows how the reasons stack up.
- Faster US launch | SimplyRCS targets 2-4 weeks against Sinch's own 6-12 week US estimate.
- No platform activation fee and no charge to change a sender profile, versus up to $500 to activate and ~$75 per change. Carrier vetting and activation charges are passed through at cost and itemized.
- Everything in one price | SimplyRCS doesn't sell the AI/bot layer as a separate $499/month product.
- Published carrier-rate pricing instead of "contact sales" for a US RCS quote.
- Human support included, not gated behind a higher tier.
A comparison that only ever flatters us is not worth reading. Here is where Sinch is genuinely the better call.
- You need messaging across many countries with one vendor and want Sinch's global operator footprint.
- You want social channels (Instagram, Facebook) managed alongside SMS/RCS in one inbox.
- You're an enterprise comfortable with custom contracts and tiered plans.
Sinch RCS pricing, what it costs
Sinch does not publish a US RCS rate card. The per-message price is quoted, so what it costs depends on your volume, your markets, and the contract you negotiate rather than on a number you can check before you talk to anyone. What Sinch does put in writing is the scaffolding around the message, and that is where most of the predictable cost sits.
The published parts
- US RCS agent activation: a one-time fee up to $500, per Sinch's own North America cost page.
- Sender-profile changes: roughly $75 each time you edit one, from the same page.
- Sinch Engage: plans from about $49 to $249 per month for the campaign and inbox tooling.
- Chatlayer, the real AI chatbot: a separate product starting near $499 per month.
- Per-message RCS rates: not published. Quote only.
The parts that are not published
Everything that actually scales. A quoted per-message rate cannot be compared against a published one without asking for the quote first, and the quote is usually tied to a committed volume. Setup timelines matter to the cost too: Sinch's own estimate for US RCS agent registration is 6 to 12 weeks, which is 6 to 12 weeks of paying for a programme that is not sending yet.
How SimplyRCS prices the same channel
Every rate is on the pricing page. RCS text is $0.0039 per message and RCS multimedia is $0.0150, the same rate inbound and outbound, and the same rate whether the message is a plain text or a rich card. The only fixed platform cost is $250 per month per verified RCS Agent, which includes the app, the API, the bot builder, the shared inbox, analytics, and human support, with no tiers and no separate AI product to license.
The fees that do exist are the carrier's, and they are passed through at cost on their own line rather than marked up or hidden in a quote: $250 to install an RCS Sender ID, $200 a year for Aegis vetting, and a one-time $500 T-Mobile sender activation. Changing a sender profile afterwards is free. That is the honest comparison: not "no fees at all", but every fee visible and at cost, against a quote you cannot see until you are in a sales process.
Where Sinch RCS stands in 2026
Sinch's RCS is open to new customers, and has been getting easier to start on rather than harder: in November 2024 Sinch announced that RCS agents can be provisioned from its Customer Dashboard and through a Provisioning API, alongside the Conversation API it has offered RCS on since 2020. The comparison above is therefore not about whether you can get RCS from Sinch, which you can, but about what it costs to find out the price, how long the US onboarding takes by Sinch's own estimate, and how many separately priced products the tooling is spread across. Verify the current fees on the Sinch page linked above before you sign; the figures here were checked in September 2026.
Sinch alternatives for US RCS
If the reason you are reading this is that Sinch quoted a long timeline or would not put a US rate in writing, these are the alternatives a US team usually shortlists, and what each is actually for.
- SimplyRCS if marketing or operations owns the channel: published rates ($0.0039 per RCS text or card, $0.0150 with media, $250 a month per verified agent), verification and 10DLC filed for you, a no-code builder and inbox, first US send in 2 to 4 weeks. US carriers only.
- Twilio if engineering owns the channel and wants the deepest ecosystem; RCS about $0.0083 basic and $0.0220 rich media plus carrier fees, self-serve verification. See SimplyRCS vs Twilio.
- Infobip if you need Sinch-style global reach with an omnichannel suite; quote-priced, enterprise onboarding. See SimplyRCS vs Infobip.
- Telnyx or Plivo if you want the lowest published API rates and will build the UI yourself. See SimplyRCS vs Telnyx and SimplyRCS vs Plivo.
- Bandwidth if you are buying wholesale carrier capacity on a contract. See SimplyRCS vs Bandwidth.
The wider list, with published rates side by side, is in the best Twilio alternatives for RCS; the same eight providers are the Sinch alternatives too.
A US business, for example in financial services, that wants to be live on RCS in weeks rather than months, with one predictable bill and every feature (including bots and two-way) included, not tiered plans, separate AI products, and a multi-month carrier timeline.

SimplyRCS vs Sinch, answered.
How long does Sinch take to set up US RCS?
Sinch's own site estimates 6-12 weeks for US RCS agent registration. SimplyRCS targets 2-4 weeks by handling brand and campaign submission for you.
Does Sinch charge to activate RCS?
In the US, Sinch lists a one-time activation fee up to $500 and about $75 per sender-profile change. SimplyRCS charges no platform activation fee and nothing to change a sender profile. The carrier charges that do apply, $250 to install an RCS Sender ID, $200 a year for Aegis vetting, and a one-time $500 T-Mobile sender activation, are passed through at cost and listed on the pricing page.
Is the AI chatbot included with Sinch?
A keyword-level builder is in Engage, but a full AI chatbot (Chatlayer) is a separate product starting around $499/month. SimplyRCS includes its no-code bot builder.
Is SimplyRCS a good Sinch alternative for US RCS?
Yes, for US business messaging. It matches Sinch's core channels (RCS, SMS, MMS, WhatsApp) on one platform, targets a 2-4 week launch instead of 6-12 weeks, and includes the bot builder and inbox that Sinch tiers or sells separately. For messaging across many countries, Sinch's global footprint is wider.
Does Sinch publish US RCS pricing?
No, US RCS is quote-based, on top of an activation fee up to $500 and per-change fees. SimplyRCS publishes carrier-rate pricing plus a flat $250/month per RCS Agent.
