SimplyRCS vs Twilio, RCS Pricing & Features (2026)

The Twilio figures below are from Twilio's US messaging pricing page, checked on 7 October 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.

Rates above are Twilio's published US figures, checked on 7 October 2026.

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 $0.022, 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 rates are below Twilio's basic and rich media rates. A text with suggested replies, a Call button or a browser link bills at the plain text rate, $0.0039 per segment, so those buttons carry no premium at all. Any rich card or carousel, and any message that carries an image or a video, bills at $0.0150, the same as an MMS, against Twilio's $0.022. 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 Twilio the process starts with a Console form you fill in. Getting a verified RCS agent through onboarding carries a $500 one-time carrier onboarding fee and $200 a year for Aegis, per sender, according to Twilio's support article. 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: $0.0083 per segment for RCS text and $0.022 per message for rich media. 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 lists them beside each rate, varying by 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.

How a long RCS message is counted

This is the mechanic that most often makes an RCS forecast wrong. Since July 2025, US RCS text is billed per 160-byte segment, like SMS, at Twilio and SimplyRCS alike, while rich media, including any card or carousel, is one flat charge per message at any length. So a long text costs several segments on either channel, and a card costs one rich media message however much text it carries. The one size-based charge is T-Mobile's: $0.001 per MB over 5 MB on rich media, which SimplyRCS passes through at cost.

The comparison that matters is the rate per segment and per rich media message: $0.0083 and $0.022 at Twilio against $0.0039 and $0.0150 on SimplyRCS. See the RCS character limit for how bytes are counted and How RCS billing works for which elements make a message rich media.

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, with no monthly platform fee on top, before carrier fees, which are itemised on their own line. Rich cards without attached media count as rich media on both platforms, so 100,000 of them are also $1,500 here against about $2,200 at Twilio. The same content sent as text with reply buttons, one segment each, is $390 here against about $830 at Twilio. 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.

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 fill in a Console form, Twilio reviews it and submits it to Aegis and the carriers, and Twilio says most senders complete the process in about five to nine weeks. 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 rates, carrier fees at cost, and no monthly platform fee, with email support free and Premium Support optional.

The RCS API overview has the SimplyRCS request shape and the webhook model; the public API reference has every endpoint.

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.
• Registrations do not move with the number. 10DLC brand and campaign filings and the verified RCS agent are tied to the provider that filed them, so they have to be re-submitted whichever platform you move to. On SimplyRCS our team prepares and files them for you; on Twilio the same work starts with a Console form you fill in.

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. For comparison, Twilio's own estimate for taking a new RCS sender through its process is about five to nine weeks for most senders (Twilio support, checked 7 October 2026). The step-by-step for leaving Twilio is in moving from Twilio without losing your numbers. Weighing other providers as well?
