# Cheapest SMS API in 2026: what does an SMS really cost? > An SMS to France costs $0.07 to $0.17 on most APIs, and a US one $0.0075 to $0.06 before 10DLC fees. Seven providers compared, plus the free route. Source: https://unlimitedmessaging.app/articles/cheap-sms-api Comparison # Cheapest SMS API: _the real price of one SMS in 2026_ SMS APIs advertise a price per message, then add carrier surcharges, registration fees, number rental and per-segment billing. Here are the published prices of seven providers to France and the United States, every fee around them, and the route that costs nothing per SMS: sending from your own phone plan. [Send SMS from your phone](https://app.unlimitedmessaging.app)[View pricing](https://unlimitedmessaging.app/pricing) The short answer ## Which SMS API is the cheapest? There is no single cheapest SMS API: it depends on the destination. To the United States, Telnyx has the lowest published rate ($0.004 per message plus a carrier fee). To France, Brevo's credits are the cheapest we found (about €0.045 per SMS), while Twilio, Plivo and ClickSend sit between $0.066 and $0.08\. Prices are on each [provider's pricing page](https://www.twilio.com/en-us/sms/pricing/fr). The headline price is rarely the bill. US carriers add a surcharge of $0.0035 to $0.005 to every message, sending from a US 10-digit number requires A2P 10DLC registration ($4.50 brand fee and $41.50 vetting at Twilio), and a message longer than 160 characters, or 70 with a single emoji, is billed as several segments. There is a cheaper route for messages to people who know you: send from the SIM card of your own phone. In France, a Free Mobile plan at €2 a month includes unlimited SMS in mainland France. Unlimited Messaging's free Android app turns that phone into an SMS gateway with an API, at a human pace (Android allows 30 SMS per 30 minutes). All prices below are the providers' published pay-as-you-go rates, read on their own pages on November 9, 2026, without volume discounts or taxes. They change often: each one links to its source.

Among the dearest to France at $0.0798 per SMS, mid-pack to the US. [Twilio↗](https://www.twilio.com/en-us/sms/pricing/us) * ### Vonage The communications API formerly known as Nexmo. Per-country rates shown on its pricing page and in the dashboard at purchase, with the same US carrier fees as everyone else. [Vonage↗](https://www.vonage.fr/communications-apis/sms/pricing/) * ### Plivo A Twilio-style CPaaS that prices slightly lower: $0.0077 per US SMS and from $0.0664 to France, with cheap US numbers at $0.50 a month. [Plivo↗](https://www.plivo.com/sms/pricing/us/) * ### Telnyx A developer-focused CPaaS with the lowest published US rate: $0.004 per message part plus carrier fees, and volume tiers below that. [Telnyx↗](https://telnyx.com/pricing/messaging) * ### ClickSend A prepaid SMS platform with a web dashboard and an API. The entry price is high ($0.0281 to the US), but falls to $0.0092 for large top-ups. [ClickSend↗](https://www.clicksend.com/us/pricing/?region=us¤cy=usd) * ### Textbelt A minimal SMS API sold in prepaid packs, popular with developers for its one-line requests and a free test text per day. Simple, but expensive outside North America. [Textbelt↗](https://textbelt.com/purchase/) * ### Brevo An email marketing suite that sells SMS as prepaid credits that never expire. Cheapest to France in this table, and usable on its free plan. [Brevo↗](https://www.brevo.com/bulk-sms-sender/) * ### Your own phone plan + Unlimited Messaging A free Android app sends SMS from your phone's SIM by API, web app, n8n or MCP. Each SMS counts against your own carrier plan, so a plan with unlimited SMS means no cost per message. The fine print ## What makes an SMS cost more than the advertised price? Five costs sit outside the per-message rate. Add them before comparing providers. 1. 01 ### US carrier surcharges AT&T, T-Mobile and Verizon charge a pass-through fee on every application-to-person SMS: $0.0035 to $0.005 per message on Twilio, Plivo, Telnyx and Vonage. On Telnyx, that fee is larger than the base rate. 2. 02 ### 10DLC and toll-free registration Sending from a US 10-digit number requires registering your brand and campaign with The Campaign Registry: $4.50 plus $41.50 standard vetting at Twilio, then a monthly campaign fee. Brevo requires a registered toll-free number for US recipients. 3. 03 ### Segments, not messages One SMS segment holds 160 GSM-7 characters. One emoji or curly quote switches the message to Unicode and cuts the segment to 70 characters, so a 150-character text can bill as three segments. 4. 04 ### Sender IDs in France To send under a brand name instead of a number in France, Twilio asks for a signed authorization to register the alphanumeric sender ID, and marketing SMS must include a STOP opt-out. Unregistered sender IDs risk being filtered. 5. 05 ### Numbers and minimum top-ups A US long code costs $0.50 to $1.15 a month, a toll-free number $2.15 to $3.44, a dedicated short code $500 to $1,000 a month. Prepaid platforms also set a minimum top-up, from $20 at ClickSend. The free route ## Can you send SMS by API from your own phone plan? Yes: an Android app can send SMS from your phone's SIM on request from your code. You pay your carrier plan, not the API, in exchange for a human sending pace. __Can you send SMS by API from your own phone plan?__ | Paid SMS APITwilio, Plivo, Telnyx, ClickSend... | Your own phone + Unlimited Messagingfree Android app | | | ----------------------------------------------- | --------------------------------------------------------- | --------------------------------------------------------------- | | Cost per SMS | $0.004 to $0.17, plus fees | €0 with a plan that includes unlimited SMS | | Registration | 10DLC, toll-free or sender ID depending on the country | None on our side: your line, your carrier's terms | | Sender | Rented number, short code or brand name | Your real mobile number, replies come back to you | | Throughput | Carrier speed, thousands per minute | 30 SMS per 30 minutes (Android's limit) | | Coverage | Any country, one account | Where your SIM works; international SMS at your carrier's rates | | Reliability | Provider infrastructure with SLAs | Depends on the phone being on, charged and connected | | Other channels | Usually SMS only, or WhatsApp and email billed separately | The same request can also go by WhatsApp or email | Free Mobile plan at €2 a month with unlimited SMS/MMS in mainland France, from mobile.free.fr, read on November 9, 2026\. Carrier plans reserve unlimited SMS for normal use: check your contract before sending business messages from a personal line. How to choose ### Pick by volume and by who you are writing to Thousands of SMS an hour, OTP bursts, strangers or a brand name as sender: a paid API, Telnyx or Plivo for the US, Brevo or Plivo for France, and budget for carrier and registration fees. A few hundred messages a day to customers, clients or guests who know your number: your own phone plan with Unlimited Messaging, at no cost per SMS. Fair play ## When is a paid SMS API worth it? Sending from your own SIM is the cheapest route, not the right one for every job. 1. 01 ### Volume and speed Android lets an app send 30 SMS every 30 minutes. A campaign to 10,000 people or a burst of login codes belongs on a provider built for throughput. 2. 02 ### Messages to strangers Cold or bulk sends from a personal line break most carrier terms and get numbers blocked. Registered business routes exist for that. 3. 03 ### A brand name as sender Alphanumeric sender IDs, short codes and verified toll-free numbers are only available through an SMS provider. 4. 04 ### Coverage and uptime guarantees A provider sends to almost every country from one account, with an SLA. A phone needs to stay on, charged and in range. FAQ ## Questions about cheap SMS APIs On published pay-as-you-go rates in November 2026, Telnyx: $0.004 per message part, plus a carrier fee of $0.0035 to $0.005, so about $0.0075 to $0.009 per SMS. Plivo ($0.0077) and Twilio ($0.0083) follow, with the same carrier fees and 10DLC registration costs. Among the providers we checked, Brevo: 100 SMS credits to France from €4.50, about €0.045 per SMS. Plivo starts at $0.0664, ClickSend at €0.0687 and Twilio at $0.0798\. Sending from your own SIM on a plan with unlimited SMS costs nothing per message. Not from a provider: carriers charge for every application-to-person SMS, and free tiers are limited to tests (Textbelt gives one free text a day). The free route is your own phone: Unlimited Messaging's free Android app sends SMS from your SIM by API, and each SMS counts against your own plan. For US traffic, Telnyx, Plivo and Twilio publish lower entry rates than ClickSend's $0.0281, which only drops to $0.0092 for top-ups from $2,000\. For France, Brevo is cheaper than ClickSend's €0.0687\. For messages to people who know you, your own phone plan costs nothing per SMS. Textbelt is simple but costs $0.06 per US text in its smallest pack and about $0.17 to Europe. A CPaaS such as Telnyx or Plivo is cheaper per message once registered. If you want Textbelt's simplicity without per-text billing, Unlimited Messaging sends from your own Android phone with one API call. A2P 10DLC is the US registration for application-to-person SMS sent from a 10-digit long code. Any business sending through an SMS API to US numbers from a long code must register its brand and campaign; at Twilio that costs $4.50 plus $41.50 standard vetting, then a monthly campaign fee. Yes. Install Unlimited Messaging's free Android app, sign in, and your SIM appears as an SMS account you can use from the REST API, the Python and TypeScript SDKs, n8n or an AI assistant through MCP. SMS leave your phone under your carrier plan, at up to 30 every 30 minutes. The Free plan costs nothing, with no credit card, and adds a short "Sent with UnlimitedMessaging.app" line to messages. Medium costs €19 a month and Max €29 a month; both remove that line. None of them bills per SMS: your carrier plan pays for the messages.
