SMS gateways for US businesses
An SMS gateway is the service that connects your business software to mobile carrier networks so you can send and receive text messages. You pay the provider a per message rate, plus a per message carrier fee that US carriers charge on 10DLC, toll-free and short code traffic, and a rental charge for the number. You reach the gateway through the REST API or SMPP of your provider, or by email to SMS and its web app. We score 15 SMS gateway and API providers, and the lowest published US rate we found was 0.35c per message on a long code, on Bird, read September 8, 2026.
