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.

What long messages cost

Every provider here, TextKit included, bills per segment: 160 plain characters, or 70 when the message has an emoji or a character outside the basic SMS alphabet. Longer messages split into parts of 153 (or 67), so a 300-character order update is two segments on the bill, and each pays the rate and the carrier fee.

The costs list prices leave out

  • Carrier fees. AT&T, T-Mobile and Verizon charge a fee on every segment of a business text. Most APIs, TextKit included, add it at cost as a separate line.
  • Segments. A long or emoji-heavy message is billed as several segments.
  • Failed messages. Twilio charges $0.001 for each message that fails (source). TextKit does not bill a message the carrier did not accept.
  • Phone numbers. A local number is $0.50 at Plivo, $1.00 at Sinch, and $1.05 at Vonage a month; $0.95 at TextKit.
  • Registration. Every US business sender registers for 10DLC. Brand and campaign fees come from the registry, and most providers pass them through.
