Choosing a Username
Twitter will do its best to set up your SMS Tweet notifications using the appropriate language settings. You can change your language settings at any time as long as the language is listed below:
Arabic (ar), Danish (da), German (de), Spanish (es), Farsi (fa), Finnish (fi), Filipino (fil), French (fr), Hebrew (he), Indonesian (id), Italian (it), Korean (ko), Malay (msa), Dutch (nl), Norwegian (no), Portuguese (pt), Polish (pl), Russian (ru), Swedish (sv), Turkish (tr), Urdu (ur), and Chinese (zh-cn).
In order to change the language settings for your Tweet notifications just send the command, SET LANG [language], to your Twitter code. For example, If you would like to change your language to Korean you would text: SET LANG KOREAN.
