The phrase pertains to the process of ensuring the SMS/MMS application on a given mobile operating system is running the most current version. This can involve updating the core application itself or, in some instances, updating carrier services that interface with the application. For example, if a user’s messaging app lacks certain features like Rich Communication Services (RCS), updating it can provide access to these newer capabilities.
Keeping the messaging application current is important for several reasons. Updates often include security patches that protect against vulnerabilities and potential malware. Furthermore, updated applications typically offer enhanced functionality, improved stability, and compatibility with the latest operating system features. Historically, the need for manual updates has evolved as mobile operating systems and app stores have become more sophisticated, often automating the update process to ensure users are always using the latest version.
