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 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.
