text message, 這是最正規的用法
以下是英文網站裏的例子：
A text message is a written message that you send using a mobile phone.
Contains thousands of text messages categorized as love notes, love letters, friendly messages, morning greetings, goodnight kisses, jokes, wise quotes, inspirational thoughts, and heavenly words! On top of these, a number of Bible verses were included to share God's message to everyone.
當然；Short Message 也有在用，但是有點中國化了，是由短信譯來的。 我們在特定清楚地語境下，可以說簡語 message, 但是message 沒有語境限制下，範圍很廣的，我們初中時學的最常用的短語之壹就是Can I leave a message? 就是留言的意思。
