An SMS gateway is a way of sending a text message with or without using a mobile (cell) phone. Specifically, it is a device or service offering SMS transit by either transforming messages to mobile network traffic from other media or by allowing transmission or receipt of SMS messages with or without the use of a mobile phone. Typical use of a gateway would be to forward simple email to a mobile phone recipient. It can also be useful in developing web applications that we can interact with via SMS (Short Messaging Service).

Some SMS gateway providers can be classified as aggregators or SS7 providers. The aggregator model is based on multiple agreements with mobile carriers to exchange 2-way SMS traffic into and out of the operator's Short Message Service Centre (SMS-C), also known as "local termination model".[citation needed] Aggregators lack direct access into the SS7 protocol, which is the protocol where the SMS messages are exchanged. These providers have no visibility and control over the message delivery, being unable to offer delivery guarantees. SMS messages are delivered in the operator's SMS-C, but not the subscriber's handset.
Another type of SMS gateway provider is based on SS7 connectivity to route SMS messages, also known as "international termination model".[citation needed] The advantage of this model is the ability to route data directly through SS7, which gives the provider total control and visibility of the complete path during the SMS routing. This means SMS messages can be sent directly to and from recipients without having to go through the SMS-C of other mobile operators. Therefore, it's possible to avoid delays and message losses, offering full delivery guarantees of messages and optimized routing.[citation needed]
Several operators have true fixed-wire SMS services. These are based on extensions to the ETSI GSM SMS standards and allow fixed-fixed, fixed-mobile and mobile-fixed messaging. These use Frequency-shift keying to transfer the message between the terminal and the SMS-C. Terminals are usually DECT-based, but wired handsets and wired text-only (no voice) devices exist. Messages are received by the terminal recognising that the CLI is that of the SMS-C and going off-hook silently to receive the message.
Implementations
Direct To Mobile Gateway Appliance
A Direct To Mobile Gateway is a device which has built-in wireless GSM connectivity. It allows SMS text messages to be sent and/or received by email, from made by acquiring a Subscriber Identity Module (SIM) web pages or from other software applications. Direct To Mobile Gateways are different to SMS Aggregators because they are installed on an organization's own network and connect to a local mobile network. The connection to the mobile network is made by acquiring a Subscriber Identity Module (SIM) card from the mobile operator and installing this in the gateway. Typically Direct To Mobile Gateway appliances are used for low to medium volume messaging.scientist[citation needed]
Direct To SMSC Gateway
A Direct To SMSC Gateway is a device which allows SMS text messages to be sent and/or received by email, from web pages or from other software applications. The Gateway connects directly to a Mobile Operator's SMSC via the Internet or direct leased line connections. It converts the message format into a format understood by the SMSC, typically this is the SMPP protocol. Direct To SMSC Gateways are used by SMS Aggregators to provide SMS services to their clients. Typically Direct To SMSC Gateways are used for high volume messaging and require a contract directly with the Mobile Operator.[citation needed].
Microsoft Outlook
Microsoft Outlook 2007 has native support for sending SMS messages worldwide via the Outlook Mobile Service.[1] There are also plug-ins for Microsoft Outlook that add this functionality.
AOL Instant Messenger
AOL Instant Messenger (AIM) version 5.2 and above has support for sending SMS messages for free.[2] Third-party client Pidgin also supports this functionality through the AIM protocol.[3]
ICQ
ICQ also has support for sending SMS messages for free.[4] Third-party client Pidgin also supports this functionality through the ICQ protocol since version 2.2.[5]
SMS send platform
Some software providers are proposing a SaaS ( software as Service ) solution to send SMS directly from an internet connected PC.
Windows Live Messenger
MSN Messenger (Windows Live Messenger) 7.0 and up have support for SMS messages.
Yahoo! Messenger
Yahoo! Messenger, accessible through a dedicated client application, or through a web site (mail.yahoo.com) have support for SMS messages.[6] Third-party client Pidgin also supports this functionality through the Yahoo! protocol since version 2.6.[7]
