Full disclosure: this guide is published by SimplyRCS, so we are on the list. Every rate quoted here was checked against the vendor's own published pricing or documentation, and where a vendor does not publish a rate we say so rather than guess. Where a competitor is the better choice, we say that too.
Why teams look for a Twilio alternative for RCS
Twilio is the best-known CPaaS in the world and reached general availability for RCS on US carriers in 2025. It is an excellent platform for engineering teams that want to assemble messaging into their own product. The reasons teams look elsewhere for RCS specifically tend to be the same four:
- The delivered cost is above the rate card. Twilio publishes about $0.0083 for a basic RCS message and about $0.0220 to send rich media, but carrier fees are passed through on top and have been reported at surcharges of 36 to 60 percent. Number rental, 10DLC registry fees and a $0.001 charge on failed messages sit alongside. The published rate is the floor, not the forecast. See SimplyRCS vs Twilio for the line-by-line version.
- Verification is self-serve. Getting a branded, verified RCS sender through Twilio means filing the submissions yourself, and Twilio's own onboarding guidance says to allow four to six weeks. There is no approval SLA and onboarding has been reported at around $700.
- There is no no-code RCS builder. Rich cards, carousels and suggested actions are built in code against the Messaging API. If marketing or support owns the channel rather than engineering, that is a standing dependency.
- Support is tiered. Human support at a useful response time is a paid add-on.
None of those is a flaw if you are a product team with engineers on the channel. They are the whole problem if you are not.
What to compare a Twilio alternative on
Six things decide whether a move pays off, and only one of them is the per-message rate.
- Published pricing, by message class. Ask for the rich text rate and the rich media rate separately, whether rich text bills per segment or per message, and whether carrier fees are passed through at cost or marked up.
- Who files verification and 10DLC. On a self-serve platform, brand registration, campaign vetting and the Google RCS agent submission are your work. On a managed platform they are the provider's.
- Time to first verified send. Weeks, not days, on every platform, because carrier approval is the long pole. The spread is 2 to 4 weeks at the fast end and 6 to 12 at the slow end.
- No-code tooling and an inbox. Whether a non-developer can build a carousel, run a campaign and answer replies without a ticket to engineering.
- Number portability. Every provider on this list can take your long codes, toll-free numbers and short codes. What differs is who does the paperwork and what has to be re-filed.
- Geography. SimplyRCS delivers on US carriers only. If your recipients are outside the United States, that rules us out before price is discussed.
The best Twilio alternatives for RCS, compared
1. SimplyRCS: best for US teams that want verified RCS live in weeks, with published rates
SimplyRCS by Signalmash is a US-only RCS platform built on direct Tier-1 connections to AT&T, Verizon and T-Mobile. The platform is free to use with no contract. Published rates are $0.0039 per RCS text or SMS and $0.0150 per RCS multimedia or MMS message. An interactive card with buttons, chips or suggested actions and no attached media bills at the text rate, which is the format most business RCS programmes send most often. The one fixed cost is $250 per month per verified RCS agent, plus a $250 agent install, with carrier vetting and activation passed through at cost on their own line.
The team prepares and files your brand registration, 10DLC campaigns and Google RCS agent submission, and targets a first verified US send in 2 to 4 weeks. The app includes a no-code bot builder, a team inbox, automatic SMS and MMS fallback where a handset cannot take RCS, and an AI agent that answers only from your approved content. Moving from Twilio means your long codes, toll-free numbers and short codes are ported for you, and 10DLC is re-filed by the team. Both platforms can run in parallel during cutover with no overlap charge.
Honest limits: US only. At low volume on rich media, a no-platform-fee API like Telnyx or Plivo can total less until the flat agent fee is earned back.
2. Telnyx: best for developer teams that want the lowest published API rates
Telnyx is a carrier-owned, developer-first platform with an unusually low rate card and free 24/7 in-house engineering support. It publishes RCS at $0.0065 per segment for rich text and $0.016 for rich media, with SMS at $0.004 per part, and charges no monthly platform fee. RCS is a secondary product next to its voice and SMS infrastructure, and there is no no-code campaign builder or inbox, so you build the UI.
Against SimplyRCS the maths is transparent because both rate cards are public. On rich text, the $250 agent fee pays for itself at roughly 96,000 messages a month, below which Telnyx is the cheaper line item. On rich media the two rates are a tenth of a cent apart, so the fee takes far longer to earn back. SimplyRCS vs Telnyx works through both crossovers.
3. Plivo: best for pay-as-you-go API access with published RCS rates
Plivo is a developer-friendly CPaaS with plans from about $25 a month and, unusually for the category, an open US rate card: $0.0077 for SMS on a 10DLC long code and the same for RCS rich text, billed per segment, with rich media at $0.0180 per message. It supports rich cards, carousels, suggested replies and verified senders properly. There is no app or inbox.
On rich text SimplyRCS's flat fee pays for itself at about 65,800 messages a month; on rich media at about 83,000. Below those volumes Plivo's pay-as-you-go total is lower. Above them, the per-message gap ($0.0039 against $0.0077 per segment on text) is where the difference is real. Full comparison at SimplyRCS vs Plivo.
4. Sinch: best for global carrier reach under one contract
Sinch is a large global aggregator with wide country coverage and the Chatlayer no-code bot builder, which can run on RCS through its Conversation API. Sinch does not publish a US RCS rate card; the per-message price is quoted against your volume and markets. Its own onboarding guidance estimates 6 to 12 weeks to a first send. Choose Sinch if you need many countries and social channels in one agreement. SimplyRCS vs Sinch has the itemised comparison.
5. Infobip: best for enterprise omnichannel suites across 60-plus countries
Infobip sells RCS as one channel inside a large omnichannel suite with direct operator connections in more than sixty countries, plus Moments for campaigns and Answers, a no-code chatbot builder that lists RCS among its channels. Pricing is quote-only, and Moments has carried a per-interaction processing fee of around $0.07. Onboarding is an enterprise process and public reviews commonly cite multi-day support response times. See SimplyRCS vs Infobip.
6. Vonage: best if you already run Vonage voice or unified communications
Vonage is a global omnichannel API alongside a unified communications business. It documents a three-class RCS billing model, Basic for text, Rich for images and carousels, and Conversation for an exchange inside a time window, but does not publish the US rates themselves. Its US SMS list rate runs around $0.0068 plus carrier fees. The channel is API-first and self-serve, so you manage verification and the build. Vonage AI Studio, its no-code agent designer, documents SMS, WhatsApp and web chat rather than RCS. Comparison at SimplyRCS vs Vonage.
7. Bird (formerly MessageBird): best for European audiences and visual flow building
Bird is a Europe-first omnichannel suite with a well-regarded visual Flow Builder, a customer data platform and AI agents that its documentation shows running on an RCS channel. It does not publish RCS rates, and its public direction has centred on AI marketing tooling. If most of your audience is in Europe it belongs on the shortlist; for a US programme, ask specifically for rich text and rich media rates and whether carrier surcharges are passed through at cost. See SimplyRCS vs Bird.
8. Bandwidth: best for large enterprises buying wholesale carrier capacity
Bandwidth owns its own nationwide US IP network and sells contract-first to enterprises and wholesalers, with an account manager, contracting and a phased launch. It publishes its fee structure (SMS and RCS rich text billed per segment, other types per message) but not the rates, which come with a negotiated contract. If you have the volume and procurement for that relationship it is carrier-grade; if you want to start without a sales cycle it is not the fit. See SimplyRCS vs Bandwidth.

How to move from Twilio without losing your numbers
You keep your numbers on every platform here. What differs is the process for each number type and how much of the paperwork the new provider does.
- Long codes move by standard US number porting. You sign a Letter of Authorization, the gaining provider validates your details against Twilio's customer service record, and a port date is scheduled. On the Twilio side the gaining carrier initiates the port. Mismatched account details are the most common cause of a rejected port, so the name and service address must match Twilio's record exactly.
- Toll-free numbers move by a change of Responsible Organization on the shared toll-free registry rather than a port. Same outcome, different process and timeline.
- Short codes are leased to your business, not to Twilio, and are migrated carrier by carrier. Carriers set migration fees that are passed through at cost: $500 T-Mobile, $250 Verizon, $150 Claro. Long codes and toll-free numbers carry no migration fee.
The part most migration plans underestimate is what does not move with the number. 10DLC campaigns are filed by the provider, so the new provider files new ones; your brand record is generally reusable. The verified RCS agent is granted through a provider's relationship with Google and the carriers, so the new provider submits a new agent for your brand and your name, logo and colours carry over while the approval does not. Opt-in records belong to you and must be carried across, not re-collected.
The safe pattern is to overlap rather than cut over cold: register and verify on the new provider while Twilio is still carrying traffic, prove delivery on a small share of volume, then move the rest and port the numbers last. On SimplyRCS the practical timeline is the same 2 to 4 weeks as a new verified send, because carrier approval rather than the port is the long pole, and there is no overlap charge. Porting a number to a new messaging provider covers each number type in detail.
How to choose
- Marketing or operations owns the channel, recipients are in the US: SimplyRCS. Published rates, approval handled, no-code builder, numbers moved for you.
- Engineering owns the channel and volume is modest: Telnyx or Plivo. Lowest published API totals until the flat agent fee is earned back.
- Recipients span many countries: Sinch or Infobip. One contract for many markets, priced by quote.
- You already run Vonage or Bird for other channels: stay in the suite if the RCS terms you are quoted are acceptable in writing.
- You are buying wholesale capacity on a contract: Bandwidth.
Whatever you pick, get the rich text rate, the rich media rate, the carrier fee treatment and the verification owner in writing before the numbers move. A free way to check whether your own handset and carrier are RCS-ready before any of this is the free sender ID test.
Frequently asked questions
What are the best Twilio alternatives for RCS messaging?
For US teams that want verified RCS live in 2 to 4 weeks with published rates and no-code tooling, SimplyRCS by Signalmash. For developer teams wanting the lowest published API rates with no platform fee, Telnyx and Plivo. For global reach across many countries under one quote-priced contract, Sinch and Infobip. Vonage and Bird fit teams already inside those suites, and Bandwidth fits enterprises buying wholesale carrier capacity on a contract.
Can I move from Twilio to another RCS provider without losing my numbers?
Yes. Long codes port through standard US number portability with a Letter of Authorization, toll-free numbers move by a change of Responsible Organization, and short codes are migrated carrier by carrier with carrier-set fees of $500 for T-Mobile, $250 for Verizon and $150 for Claro passed through at cost. 10DLC campaigns and the verified RCS agent do not transfer and are re-filed by the new provider. SimplyRCS does that filing and the porting for you, and both platforms can run in parallel during cutover.
Is SimplyRCS cheaper than Twilio for RCS?
Per message, yes on published rates: $0.0039 for an RCS text or interactive card against Twilio's roughly $0.0083, and $0.0150 with media against roughly $0.0220, with carrier fees passed through at cost rather than at reported surcharges of 36 to 60 percent. SimplyRCS adds a flat $250 per month per verified RCS agent, so at very low volume the totals converge; above a few tens of thousands of messages a month the per-message gap dominates.
Which Twilio alternatives publish their RCS pricing?
SimplyRCS ($0.0039 text, $0.0150 media), Telnyx ($0.0065 per segment rich text, $0.016 rich media) and Plivo ($0.0077 per segment rich text, $0.0180 rich media) publish US rate cards. Sinch, Infobip, Bird and Bandwidth price by quote or contract. Vonage documents its three-class billing model but not the US rates.
How long does it take to switch from Twilio to a new RCS provider?
Plan on 2 to 4 weeks on SimplyRCS, and 6 to 12 weeks on Sinch by its own estimate. Carrier approval of the new verified agent and re-filed 10DLC campaigns is the long pole, not the number port itself, which is why the safe sequence is to verify on the new provider first and port the numbers last.
Do 10DLC registrations transfer when I leave Twilio?
Campaigns do not. They are filed with The Campaign Registry by the provider acting as Campaign Service Provider, so the new provider files new campaigns. Your brand record is tied to your business and is generally reusable. On a self-serve platform that re-filing is your work; on SimplyRCS the team prepares and files it with your approval.
Does SimplyRCS work outside the United States?
No. SimplyRCS delivers on direct Tier-1 US carrier connections and its fee structure is US-regulatory. If your recipients' phone numbers are outside the United States, Sinch, Infobip or Bird are the providers on this list built for that.
