A service that allows short text messages to be sent between mobile phones and smartphones. Short Message Service. No email address is required. If a message is sent to a phone number, it will be automatically received if the recipient's mobile phone is able to receive it. The sender pays the fee. It is popular worldwide because it is cheaper than mobile phone charges. It can send several dozen full-width characters or a hundred or so half-width characters. In Japan, it was not possible to send and receive SMS between mobile phone operators, but this became possible in July 2011. It is called SMS (NTT Docomo, Softbank Mobile, E-Mobile), C-mail (au, but SMS(i) for iPhone), Litemail (Willcom), and other names vary depending on the service provider. SMS from domestic operators other than Willcom also supports international SMS with mobile phone operators in Japan. As mobile phones become more sophisticated, there are messaging services that have evolved from SMS, such as Enhanced Messaging Service (EMS), which can send decorated text, images, and voice, and Multimedia Messaging Service (MMS), which can send color images and videos. Taking advantage of the immediacy and reliability of SMS, there are cases where it is used as an emergency contact network for local governments and companies, and there are also notification services where financial institutions send account transaction information by SMS at any time to strengthen security.
