U.S. SMS Gateway

SMS Gateway facilitates communication between your application and wireless carriers. ClearLine SMS Gateway is designed to accomplish this goal. With a single interface and one time integration, we can have your application up and testing within minutes.

SMS Gateway functionality

SMS Gateways are connected to carrier networks on one side and software applications on the other side.

A request containing a message and a phone number is submitted to the gateway (through its API) that locates the country and carrier network associated with the phone number. The message is then passed to the respective carrier and sent on to the recipient’s phone number.

The diagram below demonstrates the message flow between a typical application, ClearLine SMS Gateway, and mobile users around the world:
