How we compiled this
Published self-serve pricing was collected from each provider's own US SMS/messaging pricing page on the accessed date. These are usage-based (pay-as-you-go) APIs with no fixed monthly platform fee, so monthlyUsd is recorded null for every PAYG tier and the real published per-message USD rate is captured in the plan notes; minutes/calls/overage fields stay null as they do not apply to messaging. Where a provider's official page geolocated outside the USA, returned a 403, or rendered its rate table via JavaScript (Vonage, ClickSend), the per-message figure is corroborated against a dedicated 2026 pricing source and noted; every figure is sourced and none invented. Providers whose per-message rate could not be confirmed on any live page (the official table did not render and corroborating sources disagreed) were dropped rather than retained on a guess.
