Index: https://jointextkit.com/llms.txt

**TextKit: $0.0032 per segment, plus carrier fees at cost.** The same rate on every US and Canadian carrier. Carrier fees are passed through at cost, per segment: the same fees Twilio, Plivo, Vonage, and Sinch pass through. That rate is lower than the rates of Plivo, Sinch, Twilio, Vonage, ClickSend, and Textmagic.

We compared seven SMS APIs on what a US text really costs, rate plus carrier fees, and on what each one is good for.

Rate + carrier fees: the published price of one outbound text (one segment, up to 160 plain characters) to a US mobile from a registered 10DLC number, plus the per-segment fees AT&T, T-Mobile and Verizon charge, lowest to highest. TextKit passes the same carrier fees through at cost, as Twilio, Plivo, Vonage, and Sinch do. Pay-as-you-go list prices, checked October 24, 2026.

- TextKit's rate, $0.0032 a segment, is lower than the rates of Plivo, Sinch, Twilio, Vonage, ClickSend, and Textmagic, and it costs less on every US carrier once carrier fees are added.

## How to choose

- **Sending only to the US and Canada:** Compare rates, then check the carrier fees. They add $0.0035 to $0.005 to every segment on most of these APIs, TextKit included.
- **Sending long messages:** A message over 160 plain characters, or 70 with an emoji, is split into segments, and every provider here bills each segment. See how [segments](/compare/sms-api-pricing) change your bill.
- **Need voice, WhatsApp or 100+ countries:** A multi-channel platform such as Twilio, Vonage or Sinch covers more than SMS.
- **Want a dashboard more than an API:** ClickSend and Textmagic are built for teams that text from a web app.

## How we counted

- **Source.** Each provider's own public pricing page and its carrier-fee page or help article, read on October 24, 2026. No reseller sites, no old blog posts.
- **The message.** One outbound SMS to a US mobile, from a registered 10DLC (local) number. That is the case almost every developer starts with.
- **The price.** The lowest pay-as-you-go list price, before the volume discounts or contracts most providers here offer.
- **Carrier fees.** The per-segment pass-through fees for registered 10DLC traffic on AT&T, T-Mobile and Verizon, ours included. Smaller carriers are left out. Where a provider includes them, we say so.
- **Left out.** Taxes, 10DLC brand and campaign registration (passed through at about the registry's cost by most providers here, TextKit included), MMS, and international traffic.
