What is an SMS gateway?
An SMS gateway is a point of entry or exit for SMS messages. It is a network node equipped for interfacing with another network that uses the same or different protocols.
The most common protocols used are SMPP, HTTP, UCP/EMI and SOAP. The Gateway will automatically translate any message into a format that can be delivered by the mobile network either to the message recipient, or from their mobile device back to the sending device. This means that business SMS can be sent by automated systems without requiring a mobile handset, and is therefore a key mechanism in high volume two-way communications between businesses and their customers.
