SMS Gateway

Most simply, an SMS Gateway is a device or service offering text message relay between cellular carriers (Example: Sprint) and the outside world.

An SMS Gateway is a method of sending or receiving simple 160 character text messages to or from cellular carrier network traffic. Each cellular carrier has a proprietary way of handling messages, therefore SMS Gateway providers or aggregators can do this by having individual agreements with each carrier they wish to exchange messages with. SMS Gateways are considered to be the most hassle-free way to start sending or receiving text messages to or from an application without outrageous startup fees, wait times or maintenance.
