SMS is also employed in mobile marketing, a type of direct marketing.
Marketing through cellphones' SMS (Short Message Service) became increasingly popular in the early 2000s in Europe and some parts of Asia when businesses started to collect mobile phone numbers and send off wanted (or unwanted) content.

GSM 03.40

3GPP TS 23.040 (originally GSM 03.40)3GPP 23.040 (originally GSM 03.40)3GPP 23.040
The technical standard known today was largely created by IDEG (later WP4) as the two recommendations GSM 03.40 (the two point-to-point services merged) and GSM 03.41 (cell broadcast).
GSM 03.40 or 3GPP TS 23.040 is a mobile telephony standard describing the format of the Transfer Protocol Data Units (TPDU) of the Short Message Transfer Protocol (SM-TP) used in the GSM networks to carry Short Messages.

Signalling System No. 7

SS7SS7 networkCCS7
The Mobile Application Part (MAP) of the SS7 protocol included support for the transport of Short Messages through the Core Network from its inception.
It also performs number translation, local number portability, prepaid billing, Short Message Service (SMS), and other mass market services.

Neil Papworth

The first SMS message was sent over the Vodafone GSM network in the United Kingdom on 3 December 1992, from Neil Papworth of Sema Group (now Mavenir Systems) using a personal computer to Richard Jarvis of Vodafone using an Orbitel 901 handset.
Papworth is known as the sender of the first text message (also known as SMS message) in 1992.

GSM

GSMGSM (850/900/1800/1900) GSM/GPRS/EDGE
The first action plan of the CEPT Group GSM was approved in December 1982, requesting that "The services and facilities offered in the public switched telephone networks and public data networks ... should be available in the mobile system."
The following year saw the sending of the first short messaging service (SMS or "text message") message, and Vodafone UK and Telecom Finland signed the first international roaming agreement.

Network switching subsystem

HLRMSCnetwork switching subsystem
Prior to standardized CAMEL control of the Short Message Service, IN control relied on switch vendor specific extensions to the Intelligent Network Application Part (INAP) of SS7.
The NSS originally consisted of the circuit-switched core network, used for traditional GSM services such as voice calls, SMS, and circuit switched data calls.

Digital AMPS

TDMAD-AMPSANSI-136
Although most SMS messages are mobile-to-mobile text messages, support for the service has expanded to include other mobile technologies, such as ANSI CDMA networks and Digital AMPS.
IS-136 added a number of features to the original IS-54 specification, including text messaging, circuit switched data (CSD), and an improved compression protocol.

SMS gateway

SMS Gatewayemail to/from SMS text-messageSMS Gateways
Another type of SMS gateway provider is based on SS7 connectivity to route SMS messages, also known as "international termination model".
An SMS gateway allows a computer to send or receive Short Message Service (SMS) transmissions to or from a telecommunications network.

Airwide Solutions

Mavenir Systems
The first SMS message was sent over the Vodafone GSM network in the United Kingdom on 3 December 1992, from Neil Papworth of Sema Group (now Mavenir Systems) using a personal computer to Richard Jarvis of Vodafone using an Orbitel 901 handset.
Airwide Solutions was a privately held (majority shareholder smac|partners Germany), but United States-based mobile messaging and wireless internet infrastructure company.

Short Message service center

SMSCshort message service centreshort message service center
The first commercial deployment of a short message service center (SMSC) was by Aldiscon part of Logica (now part of Acision) with Telia (now TeliaSonera) in Sweden in 1993, followed by Fleet Call (now Nextel) in the US, Telenor in Norway and BT Cellnet (now O2 UK) later in 1993.
Its purpose is to store, forward, convert and deliver Short Message Service (SMS) messages.

GSM 03.38

GSM 7-bit alphabet3GPP TS 23.038national language shift tables
Short messages can be encoded using a variety of alphabets: the default GSM 7-bit alphabet, the 8-bit data alphabet, and the 16-bit UCS-2 alphabet.
In mobile telephony GSM 03.38 or 3GPP 23.038 is a character encoding used in GSM networks for SMS (Short Message Service), CB (Cell Broadcast) and USSD (Unstructured Supplementary Service Data).

Acision

The first commercial deployment of a short message service center (SMSC) was by Aldiscon part of Logica (now part of Acision) with Telia (now TeliaSonera) in Sweden in 1993, followed by Fleet Call (now Nextel) in the US, Telenor in Norway and BT Cellnet (now O2 UK) later in 1993.
Prior to this, it was a privately held mobile communications software company specialising in messaging systems that enable popular services such as text messaging or Short Message Service (SMS), Multimedia Messaging Service (MMS), voicemail, IP Messaging, Mobile Value Added Services and Enterprise Mobility Solutions.

User Data Header

Larger content (concatenated SMS, multipart or segmented SMS, or "long SMS") can be sent using multiple messages, in which case each message will start with a User Data Header (UDH) containing segmentation information.
User Data Header (UDH) is a binary structure which may be present at the start of a short message in the Short Message Service in GSM.

For instance, there is an LED display machine controlled by SMS, and some vehicle tracking companies use SMS for their data transport or telemetry needs.
Many modern telemetry systems take advantage of the low cost and ubiquity of GSM networks by using SMS to receive and transmit telemetry data.

Short Message Peer-to-Peer

SMPPshort message peer-to-peer protocolShort Message Peer-to-Peer
The Value-added service provider (VASP) providing the content submits the message to the mobile operator's SMSC(s) using an TCP/IP protocol such as the short message peer-to-peer protocol (SMPP) or the External Machine Interface (EMI).
Short Message Peer-to-Peer (SMPP) in the telecommunications industry is an open, industry standard protocol designed to provide a flexible data communication interface for the transfer of short message data between External Short Messaging Entities (ESMEs), Routing Entities (REs) and Message Centres.

Satellite phone

All commercial satellite phone networks except ACeS and OptusSat support SMS.
They provide similar functionality to terrestrial mobile telephones; voice, SMS and low-bandwidth Internet access are supported through most systems.

Value-added service

value-added servicecontent providervalue-added services
The Value-added service provider (VASP) providing the content submits the message to the mobile operator's SMSC(s) using an TCP/IP protocol such as the short message peer-to-peer protocol (SMPP) or the External Machine Interface (EMI). Subscriber-originated messages are transported from a handset to a service center, and may be destined for mobile users, subscribers on a fixed network, or Value-Added Service Providers (VASPs), also known as application-terminated.
For mobile phones, technologies like SMS, MMS and data access were historically usually considered value-added services, but in recent years SMS, MMS and data access have more and more become core services, and VAS therefore has begun to exclude those services.

Short code

short codeshortcodeCommon short code
In this case, the VASP providing the service obtains a short code from the telephone network operator, and subscribers send texts to that number.
Short codes, or short numbers, are short digit sequences, significantly shorter than telephone numbers, that are used to address messages in the Multimedia Messaging System (MMS) and short message service (SMS) systems of mobile network operators.

IMessage

While SMS is still a growing market, traditional SMS is becoming increasingly challenged by Internet Protocol-based messaging services such as Apple Inc.'s iMessage, Facebook Messenger, WhatsApp, Viber, WeChat (in China) and Line (in Japan), available on smart phones with data connections.
iMessage allows users to send texts, documents, photos, videos, contact information, and group messages over Wi-Fi, mobile phone Internet access, or other forms of Internet access to other iOS or macOS users, thus providing an alternative to standard SMS/MMS messaging for most users with devices running iOS 5 or later.

Televoting

Mobile-originated short messages may also be used in a premium-rated manner for services such as televoting.
Televoting can also extend to voting by SMS text message via a mobile cell phone.

Long number

long numberlong numberslong code
An alternative to inbound SMS is based on long numbers (international number format, such as "+44 762 480 5000"), which can be used in place of short codes for SMS reception in several applications, such as TV voting, product promotions and campaigns.
A long number (e.g. +44 7624 80055 in international notation or 757-772-8555 in typical U.S. notation), also known as a virtual mobile number, dedicated phone number or long code, is a reception mechanism used by businesses to receive SMS messages and voice calls.

Over-the-air programming

over-the-airOTAFOTA
Short messages can send binary content such as ringtones or logos, as well as Over-the-air programming (OTA) or configuration data.
OTA via SMS optimizes the configuration data updates in SIM cards and handsets and enables the distribution of new software updates to mobile phones or provisioning handsets with the necessary settings with which to access services such as WAP or MMS.

Matti Makkonen

Makkonen, Matti
According to Matti Makkonen, the inventor of SMS text messages, Nokia 2010, which was released in January 1994, was the first mobile phone to support composing SMSes easily.
In 2008, Makkonen was awarded The Economist Innovation Award in the computing and telecommunications category for his work on text messaging (SMS).
