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.
The seven Vonage alternatives, at a glance:
- SimplyRCS, for US marketing or operations teams that want verified RCS live in weeks on published rates, with approval filed for them.
- Twilio, for engineering teams that want the widest global API surface and per-message rates they can see.
- Telnyx, for developer teams that want the lowest published API rates and free 24/7 engineering support.
- Plivo, for pay-as-you-go API access with an open US rate card and no platform fee.
- Sinch, for many countries and social channels under one contract.
- Infobip, for enterprise omnichannel across 60-plus countries with a CDP.
- Bird, for largely European audiences and a visual flow builder.
Each is worked through below, then compared in one table, then followed by what actually happens to your numbers, 10DLC registrations and verified RCS agent when you leave Vonage.
Why teams look for a Vonage alternative for RCS
Vonage's API business, the former Nexmo, is a mature omnichannel Messages API covering SMS, MMS, WhatsApp, RCS, Viber and Messenger across 160-plus countries, and since 2022 it has sat inside Ericsson alongside Vonage's unified-communications and contact-centre products. That breadth is the reason to choose it. The reasons teams look elsewhere for RCS specifically tend to be the same four:
- The US RCS rates are not published. Vonage documents how RCS is billed, in three classes, Basic for text, Rich for images and carousels, and Conversation for an exchange inside a time window, and then directs you to sales for the country rates. You cannot model a US programme from the website. SimplyRCS vs Vonage works through what the three-class model does to a forecast.
- The SMS list rate is above the published-rate peers. Vonage's US SMS list rate runs around $0.0068 plus carrier fees, against $0.0039 to $0.0077 on the providers that publish everything, and SMS is where most RCS programmes still carry most of their volume through fallback.
- Verification is self-serve, and RCS access can need a managed account. Brand registration, campaign vetting and the Google RCS agent submission are your work, and Vonage's RCS access has routed through managed or enterprise accounts rather than the self-serve dashboard.
- There is no no-code RCS builder. Vonage AI Studio, its visual agent designer, documents SMS, WhatsApp and web chat rather than RCS, so rich cards, carousels and suggested actions are built in code against the Messages API. If marketing or support owns the channel, that is a standing dependency on engineering.
None of those is a flaw if you run Vonage for voice, video or contact centre and want one vendor across many countries. They are the whole problem if you are a US team that wants RCS as the lead channel.
What to compare a Vonage 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. Coming from Vonage, ask specifically which class an unanswered outbound rich card falls into, because that is the question the three-class model leaves open.
- 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, and the global aggregators are the honest comparison to Vonage.
The best Vonage 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 Vonage 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, so a programme that also texts Vonage's other 160 countries needs a second provider for them. 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. Twilio: best for engineering teams that want the widest API surface with visible rates
Twilio is the best-known CPaaS in the world and the closest like-for-like swap for a team that wants to stay API-first. Unlike Vonage it publishes its US RCS rates: $0.0083 per segment for a rich message and $0.022 for rich media, with carrier fees itemised per carrier on top (from $0.0045 to $0.0062 on rich text and $0.007 to $0.0135 on rich media), a $1.15 monthly long-code rental and a $0.001 fee on messages that end in a failed status. Verification is self-serve with no approval SLA, and rich cards and carousels are built in code. Choose Twilio if engineers own the channel and you want the widest global surface with rates you can at least see. SimplyRCS vs Twilio has the line-by-line comparison, and best Twilio alternatives for RCS is the companion to this guide.
3. 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 per message for rich media, with 10DLC SMS at $0.004 per message part, and states a $0 platform fee outright. 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.
4. Plivo: best for pay-as-you-go API access with published RCS rates
Plivo is a developer-friendly CPaaS with, 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, with rich media at $0.0180 per message, carrier surcharges listed per carrier alongside, and long codes at $0.50 a month. 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 on text) is where the difference is real. Full comparison at SimplyRCS vs Plivo.
5. Sinch: best for global carrier reach under one contract
Sinch is the most direct alternative to what Vonage actually sells: a large global aggregator with wide country coverage, social channels and the Chatlayer no-code bot builder, which can run on RCS through its Conversation API. Like Vonage it 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 the reason you chose Vonage was many countries in one agreement and the reason you are leaving is not price transparency. SimplyRCS vs Sinch has the itemised comparison.
6. 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. For a Vonage customer it is the closest match on breadth, with a CDP and a no-code builder that Vonage's RCS does not have. See SimplyRCS vs Infobip.
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.

What Vonage charges for RCS, and why it is hard to compare
The question behind most "Vonage RCS pricing" searches has no public answer, so here is the structure at least. Vonage bills RCS in three classes. Basic is a text-only message. Rich is a message with an image, a card, a carousel or another interactive element. Conversation covers an exchange inside a time window as one billable unit rather than per message. The rates for each are given by sales per country.
The three-class model changes how you forecast. Under per-message billing a support conversation with fifteen replies costs fifteen messages. Under conversation billing the same exchange is one unit inside the window, which is cheaper for genuinely two-way traffic and more expensive for one-way notifications that never get a reply. Neither is better in the abstract. What it means for a comparison is that a Vonage quote has to be read against your actual mix of broadcast and conversational traffic, and the alternatives above that publish one rate per message class are simply easier to model. On SimplyRCS an interactive card with buttons and no media bills at the text rate, and there is no conversation class at all.
How to move from Vonage 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 Vonage's customer service record, and a port date is scheduled. Mismatched account details are the most common cause of a rejected port, so the name and service address must match Vonage'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 Vonage, 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.
- One Vonage-specific check. If your numbers sit on Vonage Business Communications, the phone system, rather than on the Messages API, the port-out request goes through that account and its contract terms apply. Confirm which side of Vonage holds each number before you schedule anything.
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 Vonage 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.
Vonage competitors, by category
"Vonage competitors" and "Nexmo competitors" cover three different kinds of company, and comparing across the kinds is where most shortlists go wrong.
- Global aggregators and omnichannel suites. Sinch, Infobip and Bird compete with Vonage on its own ground: many countries, many channels, one contract, quote-based pricing. LINK Mobility is the European equivalent. Twilio sits here on breadth but differs by publishing its rates.
- Developer-first APIs with published rates. Telnyx and Plivo compete on a public rate card and the expectation that you build the campaign tooling, inbox and approval workflow yourself. They win on price at low volume; they do not change who does the work.
- Managed, US-focused platforms. SimplyRCS competes by removing the work rather than repricing it: the app, inbox and carrier approval are included, and the rate card is public. TrueDialog is the SMS-first version of the same idea; RCS Studio by Vibes is the RCS-only, enterprise-marketing version.
If the question is "who matches Vonage's reach," it is the first group. If it is "who will get a US programme live in weeks without an engineering project," it is the third. SimplyRCS alternatives puts all twelve on one page.
Vonage alternatives for SMS, not only RCS
Every provider here also sends plain SMS, and for many programmes SMS remains most of the volume, because RCS falls back to it wherever a handset cannot take RCS. The published US SMS rates for a 10DLC long code, all before carrier fees:
| Provider | SMS, per message | Notes |
|---|---|---|
| SimplyRCS | $0.0039 | Same rate as an RCS text; carrier fees passed through at cost |
| Telnyx | $0.004 per part | Published; $0 platform fee |
| Vonage | ~$0.0068 | List rate; carrier fees on top |
| Plivo | $0.0077 | Published; long codes $0.50/mo |
| Twilio | $0.0083 | Plus itemised carrier fees, $1.15/mo number rental |
| Sinch, Infobip, Bird | Quoted | Not published for the US |
Two things to check beyond the rate. First, whether SMS is billed per message or per 160-character segment, which changes the cost of anything longer than a short sentence. Second, whether carrier surcharges are passed through at cost or marked up; on a $0.004 message a marked-up surcharge can be the larger line. 10DLC, toll-free and short codes explained covers which number type each rate applies to.
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.
- You want to stay API-first but see the rates: Twilio, or Telnyx and Plivo if the lowest published total matters more than breadth.
- Recipients span many countries and the reason you chose Vonage still stands: Sinch or Infobip. One contract for many markets, priced by quote.
- Audience is mostly European: Bird.
- You run Vonage for voice, video or contact centre and RCS is a small part of it: stay, if the RCS terms you are quoted are acceptable in writing.
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 Vonage 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 teams staying API-first, Twilio publishes the rates Vonage does not, and Telnyx and Plivo publish the lowest totals with no platform fee. For the many-country reach that Vonage is chosen for, Sinch and Infobip are the like-for-like alternatives, and Bird fits a European audience.
Does Vonage publish its RCS pricing?
No. Vonage documents a three-class billing model, Basic for text, Rich for images and carousels, and Conversation for an exchange inside a time window, and gives the per-country rates through sales. Its US SMS list rate runs around $0.0068 plus carrier fees. Of the alternatives, SimplyRCS, Twilio, Telnyx and Plivo publish full US RCS rate cards.
Is SimplyRCS cheaper than Vonage?
On SMS, yes on list rates: $0.0039 against roughly $0.0068, both before carrier fees, and SimplyRCS passes carrier fees through at cost. On RCS a like-for-like comparison needs the Vonage quote, because the US rates are not public. 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.
Can I move from Vonage 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 Nexmo the same as Vonage?
Yes. Nexmo was the CPaaS that Vonage acquired in 2016 and rebranded as the Vonage Communications APIs, and since 2022 the whole company has been part of Ericsson. A search for a Nexmo alternative or Nexmo competitor is a search for a Vonage API alternative, and the list above applies.
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, which is also the one case where staying with Vonage may be the right answer.
