An S-M-S gateway allows a computer to send or receive Short Message Service (S-M-S) transmissions to or from a telecommunications network. Most of the messages are finally scattered into the mobile phone networks. Many bulk SMS provider gateways support media conversion from email and other formats.
Several mobile telephone network operators have true fixed-wire S-M-S services. These depends on addendum to the European Telecommunications Standards Institute (E-T-S-I) Global System for Mobile Communications (G-S-M) S-M-S standards and allow messaging between any mix of fixed and mobile equipment. These use frequency-shift computing to transmit the message between the terminal and the S-M-S-C. Terminals are typically depends upon Digital Enhanced Cordless Telecommunications (D-E-C-T), but wired handsets and wired text-only (no voice) devices exist. Messages sent through the bulk SMS service are received by the terminal identifying that the Caller ID is that of the S-M-S-C and going off-hook silently to receive the message.
G-S-M gateway appliance
A direct-to-mobile gateway is a device which has built-in wireless G-S-M connectivity. It allows S-M-S text messages to be sent and received by email, from Web pages or from other software applications by receiving a distinctive identifier from the mobile phone’s Subscriber Identity Module or S-I-M card. Direct to phone gateways are dissimilar from S-M-S accumulators, because they are installed on an organization’s own network and linked to a community mobile network.
The link to the mobile network is made by acquiring a SIM card number from the mobile mechanic and locating it in the bulk SMS gateway provider gateway. Usually, direct-to-mobile gateway appliances are used for hundreds to thousands of messages every month. Much more advance appliances now offer the capability of send up to 100,000 messages everyday. A large number of vendors that have historically provided G-S-M Gateway equipment for voice also have S-M-S capability for different types of SMS. Some are more original than others. More competent devices are designed with SIM management to regulate the number of S-M-S messages per SIM, O-D-B-C to connect to a database, and HTTP interfaces to interact with third party applications.
G-S-M gateway equipment is covered by the Wireless Telegraphy Act in the UK and can legally be used by any business to transmit S-M-S to their own customers when using their own gateway equipment. In India it is controlled by the Telecom Regulatory Authority of India ( i.e. T-R-A-I).

The short messages Peer-to-Peer (S-M-P-P) protocol is typically used to convey S-M-S between an application and the S-M-S-C. Direct to S-M-S-C gateways are used by S-M-S accumulator to provide S-M-S services to their customers and huge businesses who can explain such use. They are basically employed for huge volume messaging and require a compact directly with a mobile operative.
An S-M-S gateway typically sits betwixt the end user who needs to send or receive S-M-S and a mobile network’s S-M-S-C. Such gateways provide a choice of protocols, including HTTP, S-M-T-P, S-M-P-P and Web services. Providers of S-M-S gateway services include S-M-S accumulator and mobile operators.
