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.
