Twilio is the best-known CPaaS in the world: a mature, global, API-first platform that reached general availability for RCS on US carriers in 2025. It is built for engineering teams that want to assemble messaging into their own product. RCS basic messages are priced like SMS at about $0.0083, while rich media runs roughly $0.0220 to send and $0.0165 to receive, with carrier onboarding and per-message carrier fees on top. Twilio does not ship a built-in messaging dashboard or shared inbox, you build that yourself.

Where each one is the right call.
Weigh both sides. The bar shows how the reasons stack up.
- No code required, marketing teams launch in a no-code builder; Twilio expects you to build the interface and the inbox yourself.
- White-glove US carrier approval included, versus Twilio's self-serve submission with no approval SLA.
- One transparent bill, carrier rates plus a flat $250/month per RCS Agent, with fees itemized; Twilio layers number rentals, carrier fees, registration, and a failed-message fee.
- An interactive rich card costs the same as a plain text, $0.0039, and a message carrying media is $0.0150 against Twilio's roughly $0.0220.
- API and app at the same price, every feature included, no separate products to license.
A comparison that only ever flatters us is not worth reading. Here is where Twilio is genuinely the better call.
- You have an engineering team that wants maximum global API surface and is happy to build and maintain the UI.
- You operate in many countries and need Twilio's breadth of international routes and products.
- You're already deep in the Twilio ecosystem (Voice, Verify, Segment) and want one vendor for everything.
Twilio RCS pricing in 2026
The Twilio figures below are from Twilio's US messaging pricing page, checked on 8 September 2026, which lists the per-carrier fees beside each rate.
Twilio publishes its RCS rates, which is more than most of the category does, but the published rate is not the bill. Twilio prices RCS by message class, charges more for rich media than for basic text, and then layers carrier fees, number rentals, and registration costs on top. Here is the rate card next to ours.
| What you are billed for | Twilio, published rate | SimplyRCS |
|---|---|---|
| RCS basic text, sent | ~$0.0083 per message | $0.0039 per message |
| RCS rich card, no media | Billed as basic text | $0.0039 per message |
| RCS rich media, sent | ~$0.0220 per message | $0.0150 per message |
| RCS rich media, received | ~$0.0165 per message | $0.0150 per message |
| Platform fee | None, pay as you go | None; $250/month per verified RCS Agent (how that differs from a platform fee) |
| Sender onboarding | One-time carrier onboarding fee per sender, amount not published | $250 agent install, plus carrier vetting and activation at cost |
| Carrier fees | Passed through, published at $0.0025 to $0.02 per message | Passed through at cost, on their own line |
| Failed messages | $0.001 each | Not billed |
| Phone numbers | Monthly rental per number | Included |
| Campaign registration | 10DLC brand and campaign fees, you file | Carrier fees at cost, we file |
Rates above are Twilio's published US figures as of June 2026, verify current pricing with Twilio directly.
Why the rich media rate is the one that matters
The headline people quote is $0.0083, because that is Twilio's basic RCS rate and it matches SMS. But basic RCS is text. The reason to run RCS at all is the rich part: the carousel, the image, the branded card, the suggested-action chips. That traffic is billed at roughly $0.0220, about two and a half times the headline, so a campaign built the way RCS is meant to be built prices off the higher number, not the one in the comparison articles.
SimplyRCS splits the same traffic two ways rather than three, and both halves are lower. A rich card with buttons, chips or suggested actions but no attached media bills at the plain text rate, $0.0039, so the interactive part of RCS carries no premium at all. A message that actually carries an image, a video or a carousel bills at $0.0150, the same as an MMS, against Twilio's roughly $0.0220. Both figures are on the pricing page.
What a Twilio RCS bill is actually made of
The rate card answers "what does a message cost". It does not answer "what will the invoice say", and those are different questions. A Twilio RCS bill has four layers, and only one of them is the number people quote.
Before you send anything. Phone numbers rent monthly, per number. 10DLC brand and campaign registration carries Campaign Registry fees, and on a self-serve platform you file them yourself. Getting a verified RCS agent through onboarding carries a one-time carrier fee, which Twilio's guidelines confirm without publishing the amount. None of this is per message, and all of it is spent before the first send.
Per message, by class. This is the rate card: roughly $0.0083 for basic RCS text and $0.0220 for rich media, with rich media received at about $0.0165. The class is decided by what the message contains, so the same campaign can bill at two different rates depending on whether a given send carries a card.
On top of every message. Carrier fees are passed through rather than absorbed, and Twilio publishes them beside each rate at $0.0025 to $0.02 per message depending on carrier and message type. They are the layer that moves a forecast furthest, because they scale with volume exactly as the message rate does and are easy to leave out of the plan.
The lines you did not plan for. Failed messages bill at $0.001 each. Number rental continues whether or not you send. Neither is large on its own; both are invisible until the invoice.
One RCS message is not one SMS segment
This is the mechanic that most often makes a Twilio RCS forecast wrong, and it cuts in your favour.
SMS bills per 160-character segment, so a 400-character message is three billable segments. RCS bills per message, and one RCS message carries up to 3,072 characters. A long message that would have been three or four SMS segments is a single billable RCS message.
That means a like-for-like comparison of "RCS costs more than SMS" is often wrong for longer content: at $0.0083, basic RCS matches Twilio's SMS rate per message, while SMS is charged per segment. Where it stops helping is rich media, which is billed per message at the higher class and is the whole reason to use the channel. See the RCS character limit for the segment maths.
A worked example, 100,000 rich RCS messages
At Twilio's published rich media rate, 100,000 sends is about $2,200 in message charges before anything else. Add per-message carrier fees, the numbers you rent, the registration filings, and a share of failed messages, and the real number lands meaningfully higher. Twilio does not dispute this, it is simply how pay as you go plus pass-through works, and it is why forecasting a Twilio bill is its own job.
On SimplyRCS the same 100,000 rich media messages are $1,500 in message charges at $0.0150 each, plus one flat $250 monthly charge per RCS Agent, so $1,750 before carrier fees, which are itemised on their own line. Send those same 100,000 as rich cards without attached media and the message charge is $390 rather than $1,500, because a card with buttons bills at the plain text rate here and at Twilio's basic rate there. Both numbers are on the pricing page and the method is written out in billing transparency. For the category-wide breakdown, see RCS pricing by provider.
To put your own volume through it rather than ours, the RCS ROI calculator takes a monthly send count and returns the cost side and the engagement lift side together.
Twilio RCS API vs the SimplyRCS API
Both are REST APIs with webhooks, and both send RCS through Google's RBM programme underneath. The differences are in what surrounds the call.
- What the API includes. Twilio's is the product: you get sending, receiving and events, and build the campaign tooling, inbox and approval workflow on top. The SimplyRCS API is the same interface the app uses, so the builder, inbox, templates and analytics exist already and the API reaches into them; there is nothing to license separately, and the API and the app carry one price.
- Agent onboarding. On Twilio you create and submit the RCS sender yourself, self-serve, with no approval SLA. On SimplyRCS the agent is prepared and submitted for you, with a first verified US send targeted at two to four weeks.
- Fallback. Both fall back to SMS. On SimplyRCS it is automatic per recipient on every send and reported per channel; on Twilio it is configured on your side through a Messaging Service, and the per-channel reporting is yours to build.
- Pricing lines. Twilio bills per message plus carrier fees, number rentals, registry fees and a $0.001 charge on failed messages, with production support paid; SimplyRCS bills the published per-message rate, carrier fees at cost, and $250 a month per verified agent, with support included.
The RCS API overview has the SimplyRCS request shape and the webhook model; the public API reference has every endpoint.
Migrating from Twilio, and what happens to your numbers
You keep your numbers. SimplyRCS ports long codes, toll-free numbers, and short codes off Twilio, and re-files your 10DLC brand, your campaigns, and your verified RCS agent with the carriers on your behalf. You approve the filings; you do not assemble them.
Both platforms can run in parallel during cutover, so you move traffic when you are ready rather than on a switchover date. There is no overlap charge from us for running both.
Two things worth knowing before you plan the move:
- Short-code migrations carry carrier fees, set by the carriers and passed through at cost: $500 T-Mobile, $250 Verizon, $150 Claro. Long codes and toll-free numbers do not carry a migration fee.
- 10DLC registrations do not transfer. Brand and campaign filings are tied to the provider, so they have to be re-submitted whichever platform you move to. On SimplyRCS our team prepares and files them; on a self-serve platform that work lands on you.
The practical timeline is the same 2 to 4 weeks we target for a new verified US RCS send, because carrier approval, not the port, is the long pole. The step-by-step for leaving Twilio is in moving from Twilio without losing your numbers. Weighing other providers as well?

SimplyRCS vs Twilio, answered.
Is SimplyRCS a good Twilio alternative for RCS?
Yes. It covers the same core channels and adds a no-code app, a built-in two-way inbox, white-glove carrier approval, and published carrier-rate pricing, the pieces Twilio leaves to you.
Is SimplyRCS cheaper than Twilio?
Typically, once you count Twilio's carrier fees, number rentals, registration, and the higher rich-RCS rate. SimplyRCS charges $0.0039 for an RCS text or an interactive card and $0.0150 for a message carrying media, plus a flat $250/month per RCS Agent, and both of those rates sit below Twilio's equivalents.
Can I move from Twilio to SimplyRCS without losing my numbers?
Yes. SimplyRCS ports your long codes, toll-free numbers, and short codes off Twilio and keeps them, and re-files your 10DLC brand, campaigns, and verified RCS agent with the carriers for you. Both platforms can run in parallel during cutover, so traffic moves when you choose. Short-code migrations carry carrier-set fees passed through at cost ($500 T-Mobile, $250 Verizon, $150 Claro); long codes and toll-free numbers do not.
How much does Twilio RCS cost?
Twilio publishes about $0.0083 per basic RCS message, the same as its SMS rate, and about $0.0220 to send rich media with $0.0165 to receive. Those are message charges only. Per-message carrier fees, a one-time carrier onboarding fee per RCS sender (Twilio's US RCS guidelines say carriers charge one, without publishing the amount), monthly phone number rentals, 10DLC registration, and a $0.001 failed-message fee sit on top, so the delivered cost runs above the published rate.
Is Twilio RCS pricing cheaper than SimplyRCS?
SimplyRCS is lower on both classes. Twilio prices basic RCS at roughly $0.0083 against $0.0039 here, and rich media at roughly $0.0220 against $0.0150 here, and SimplyRCS adds one flat $250 per month per RCS Agent. The larger difference is where the line between the classes falls: an interactive card with buttons and no attached media bills at the plain text rate on SimplyRCS, so the interactive part of RCS carries no premium. Once number rentals, onboarding, and carrier surcharges are counted, SimplyRCS is typically lower and always easier to forecast.
Does Twilio include an inbox or campaign builder?
No. Twilio is API-first and doesn't ship a built-in dashboard or shared inbox; you build those. SimplyRCS includes both.
How fast can you launch RCS on SimplyRCS versus Twilio?
SimplyRCS targets a first verified US RCS send in 2-4 weeks and prepares and submits your brand and campaign registrations for you. Twilio is self-serve with no published approval SLA: you build the integration and file the carrier registrations yourself, so timelines vary.
Does SimplyRCS cover the same US channels as Twilio?
For US business messaging, yes, on one platform: RCS, SMS, MMS, toll-free, short codes, and 10DLC, with a shared inbox and no-code builder included. Twilio reaches the same channels through its APIs but expects you to build the dashboard. For reach beyond the US, Twilio's global routes are wider.
Does Twilio bill RCS per message or per segment?
Per message. SMS is billed per 160-character segment, so a long text is several billable segments, but an RCS message is billed once and carries up to 3,072 characters. That is why "RCS costs more than SMS" is often wrong for longer basic messages, and right for rich media, which is billed per message at the higher class.
What do you pay on Twilio before sending a single RCS message?
Phone number rental, which is monthly and per number, 10DLC brand and campaign registration fees that you file yourself, and RCS agent onboarding, a one-time carrier fee whose amount Twilio does not publish. None of it is per message, and all of it lands before the first send. On SimplyRCS the equivalent is a $250 agent install plus carrier vetting and activation passed through at cost, and we file the registrations.
Why is my Twilio RCS bill higher than the rate card?
Usually three layers that are not on the rate card: carrier fees passed through on top of every message, $0.0025 to $0.02 each at Twilio's published rates; number rental that continues whether or not you send; and a $0.001 charge on failed messages. The published per-message rate is the floor, not the forecast.
What does Twilio RCS messaging cost compared with SimplyRCS?
Twilio RCS messaging is priced like SMS for a basic message, about $0.0083, and roughly $0.0220 to send or $0.0165 to receive with rich media, plus carrier fees per message and a one-time carrier onboarding fee per sender. SimplyRCS lists $0.0039 for an RCS text and $0.0150 with media, with carrier fees passed through at cost.
How does Twilio SMS API pricing compare?
Twilio SMS API pricing in the US starts at about $0.0083 per segment plus carrier fees and monthly number rental, and a long SMS is billed per 160-character segment. SimplyRCS bills SMS at $0.0039 with carrier fees at cost, and the API costs the same as the app.
