Best SMS gateway providers in the USA
Kudosity (formerly BurstSMS) scores highest of the 34 eligible US providers, at 8.17 out of ten on six equally weighted criteria. The lowest captured reference rate in this table is Bird (formerly MessageBird) at 0.35c. Your volume and number type determine the rate that applies. The lowest captured flat message rate is Clickatell at 0.751c flat. 11 further providers are reviewed and scored on this site but are not ranked here, because they publish no US per message rate, no capability set, or both.

- Sinch, 8.00 out of 10. Highest scored criterion: features (9.0). From 0.78c per SMS, by number type, read 9 September 2026.

"Highest scored criterion" is the criterion each provider scores highest on of the six we publish; the order is this page's ranking. How we rate.
SMS providers for different requirements
Kudosity for fee-included sending
Kudosity charges $0.015 per segment at 10,000 monthly segments, read from its US global pricing page on 8 September 2026. That rate includes 10DLC and toll-free carrier pass-through, so the carrier line item you compare elsewhere does not appear here.
Included carrier fees do not remove number rental or other charges, so check the rental line before you budget.
Telnyx for low sender-specific rates
Telnyx lists a local and 10DLC rate of $0.004 per part before carrier pass-through, captured from its messaging pricing page on 9 September 2026. Because each sender type carries its own rate, you pay the rate for the number type you actually register.
Pay as you go carries no monthly commitment, so check the actual applicable sender rate and pass-through charges against your sending pattern. Its pricing plan was observed on 22 September 2026.
Twilio and Sinch for estimating carrier costs
Twilio's entry outbound rate is $0.0083 per segment, captured from its US SMS pricing page on 8 September 2026, and a long-code number rents at $1.15 per month on the same capture. Those published components let you estimate the captured message, rental and carrier parts of a bill.
The final price still depends on applicable setup, registration, support, inbound and tax.
Sinch charges $0.0078 per 10DLC segment, read from its SMS pricing page on 9 September 2026. Sinch adds carrier charges on top, and its amounts were not published on the checked pages.
You can estimate Twilio's captured components more precisely, while Sinch requires you to ask for its carrier amounts.
Bird and Plivo for rate floors and minimums
Bird's captured long-code and toll-free reference rate is $0.0035 per segment, read from its SMS pricing page on 8 September 2026. Carrier and third-party transit charges are additional, and Bird publishes those on a separate fee schedule captured 9 September 2026.
A low reference rate narrows the comparison but does not settle the complete bill.
Plivo lists $0.0077 per long-code and short-code segment before carrier charges, read from its US SMS rates page on 9 September 2026. Its captured US plan table makes SMS Enterprise only, with a $1,000 per month minimum on the pricing page read 22 September 2026.
The Enterprise minimum must be included when evaluating the monthly commitment, even when message charges calculate to less.

What it costs at your volume
Only the providers publishing one flat rate can be priced this way. For everyone else the published rate is keyed to a plan, a top up amount, a credit bundle or a number type, none of which a volume slider knows.
| Provider | Rate applies | Rate | Monthly |
|---|---|---|---|
| Clickatell | Flat, any volume | 0.751c | $113 |
| Infobip | Flat, any volume | 0.818c | $123 |
| Vonage | Flat, any volume | 0.86c | $129 |
| SMSGlobal | Flat, any volume | 1.90c | $285 |
| CallHub | Flat, any volume | 1.90c | $285 |
| Notifyre | Flat, any volume | 2.00c | $300 |
| Textmagic | Flat, any volume | 4.90c | $735 |
Only the 7 flat rate providers appear here, because they are the only ones where a monthly figure is arithmetic instead of a guess. Carrier surcharges, number rental and 10DLC fees land on top. Every published rate.
SMS deliverability and carrier filtering
Twilio's documentation says a message can be filtered by Twilio for spam, phishing or fraud, or by a carrier for violating carrier rules or regulations. Twilio also says registering for A2P 10DLC results in lower message filtering and higher throughput, and unregistered 10DLC traffic draws additional carrier fees. On their route to US carriers, 9 of the 15 scored gateways claim direct carrier connections, 2 route through partners, 1 is an aggregator, 1 a carrier or network owner, and 2 state no route. The full route comparison is on the SMS aggregators page.
Several of the SMS gateway providers in this comparison now sell RCS business messaging beside SMS, and that page lists which of the scored providers publish it.

SMS provider selection by workflow
Match the interface to your systems
Check whether the provider documents an integration for your source system, whether the recipient upload format fits your list, and whether scheduled sending, opt-out recording and reply handling work the way your campaign needs.
Some buyers run everything from a dashboard, others automate from their own software, and many use both. Choose by the features each provider actually documents rather than by category labels.
For interface depth, read Best SMS API, Business text messaging and SMS marketing platforms.
Match the sender type to approval and throughput
Different sender types carry provider-specific limits. Before you commit, check the required approval for the sender type you want and the throughput the provider applies to it.
Our 10DLC registration and SMS short codes pages explain the approval paths. The route table on this page quotes vendor descriptions, not a comparative delivery measurement, so treat throughput figures as published limits rather than tested speeds.
Match the contract to your support needs
Check the support channels and hours against the times you actually send, and read the contract SLA for its plan scope, credits and exclusions. An uptime figure a provider states on its website is a claim about that service, not a guarantee of your message delivery.
Where a provider restricts a plan tier, such as Plivo's Enterprise gate for SMS, the contract terms decide whether it fits your volume.
SMS gateway comparison method
Eligibility for the best-provider table requires a published US rate and recorded number capabilities. Of 45 provider reviews, 34 records meet both tests.
The eligible set includes marketing platforms whose capabilities differ from developer gateways, so compare rows on the attributes you need rather than treating the set as interchangeable.
The overall score is the rounded mean of six equally weighted criteria: value, features, reliability, reputation, compliance and customer service. Every provider on the site is scored on the same criteria, so the score supports comparison across the table. The How we rate SMS providers page explains each criterion.
A separate API cohort covers 15 providers, of which 12 carry a numeric developer fit score. Three were not assessed because particular criteria were unread. The API score assesses eight documentation criteria, not runtime performance.
We opened no accounts and sent no test traffic. Rate cells and linked reviews identify the individual source observation dates, and SMS gateway prices carries the price detail.
SMS gateway provider FAQs
What is an SMS gateway provider?
An SMS gateway provider sends business messaging through documented interfaces such as an API or dashboard. Providers differ in reply handling, sender types and pricing models, so check each one's documentation.
Why do providers differ despite similar scores?
The overall score averages six criteria. The average does not show each criterion or each provider's pricing conditions, so read the score breakdown and the price rows together.
Do I need a dashboard or an API?
That depends on your source integration, automation needs and reply handling. Some providers offer both, others emphasize one. Check what each provider documents for your workflow.
Why does a low rate differ from the monthly bill?
A quoted rate covers a defined scope. Number rental, carrier pass-through, plan minimums and taxes add to it, and some providers include carrier fees while others add them separately.
Does the site test delivery?
No. This site compares published source documentation and does not send its own traffic. Delivery and throughput figures quoted here are vendor claims, attributed and dated in the tables.
Is an SMS provider the same as an SMS gateway provider?
Yes. On this site an SMS provider is a company selling application to person SMS to US businesses by API, web app or both, and searchers use SMS provider, SMS service provider and SMS gateway provider for the same company class.
Does a commission change these rankings?
No. Some providers pay a commission when a reader signs up through a link here, and that is disclosed on this page. The order comes from the six scoring criteria and nothing else. How we make money.
