Twilio is the global, API-first CPaaS you build on; SimplyRCS is the done-for-you US RCS platform you launch on. Choose Twilio if engineers want maximum global API surface and will build the UI and inbox themselves. Choose SimplyRCS if a marketing or ops team wants branded RCS live in weeks, carrier approval handled, and one predictable carrier-rate bill.
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.
- Rich RCS costs the same as basic; on Twilio rich media is priced well above basic.
- 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
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 | Carrier rate, published |
| RCS rich media, sent | ~$0.0220 per message | Same rate as basic |
| RCS rich media, received | ~$0.0165 per message | Same rate as basic |
| Platform fee | None, pay as you go | $250/month per RCS Agent |
| Sender onboarding | Reported around $700 | $0 |
| Carrier fees | Passed through, reported at 36 to 60% surcharges | 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 |

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.
On SimplyRCS rich and basic are the same rate, so the message you actually want to send is not the expensive one.
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 messages bill at the published carrier rate plus one flat $250 monthly charge per RCS Agent, with carrier fees itemised on their own line. Both numbers are on the pricing page and the method is written out in billing transparency. For the category-wide breakdown, see how much RCS costs.
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.
A US-focused marketing, CRM, or operations team, for example in retail and e-commerce, that wants to launch branded RCS without building software, wants carrier approval handled, and wants a bill it can actually predict, rather than an API toolkit and a stack of carrier and number fees.

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 the carrier rate plus a flat $250/month per RCS Agent, with rich priced the same as basic.
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, sender onboarding reported around $700, 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?
On the basic text rate the two are close, because both track the carrier rate. The gap opens on rich media, which is where RCS earns its keep: Twilio prices it at roughly $0.0220 against $0.0083 for basic, while SimplyRCS charges the same rate for both and adds one flat $250 per month per RCS Agent. 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.
