Twitter is a real-time information network that connects you to the latest breaking news, trends, gossip, or other information that is interesting to you. With Twitter you can either follow public streams, or sign up with Twitter to follow other Twitter users and add them to categorical lists. Twitter users can also follow you and add you to their lists, too. You can use Twitter at your home or work computer, and Twitter is also available on mobile devices.

If you already have a Twitter account, you can use Twitter from your phone using SMS or by using your phone’s mobile browser to visit Twitter’s mobile website at mobile.twitter.com. You can also create a new Twitter account via SMS by sending the word START to your Twitter shortcode, which is 40404 in the US. (Visit twitter.com for a full list of Twitter shortcodes.) You can also create an account by visiting mobile.twitter.com and then confirming your email address. It’s important to note that Twitter is a free service, and Twitter doesn’t charge users, even via SMS. Your mobile carrier may charge you for text messages, though.

To use Twitter from your phone to post a tweet, just send a text message to your shortcode. If you’re getting too many updates from Twitter, there are several options to turn updates off. Here’s a few commands you can use to control the updates you get when you use Twitter from your phone:

  • ON: turns ALL your authorized Twitter updates and notifications on.
  • OFF: turns off all updates except direct messages. Send STOP again to turn off direct messages too.
  • STOP, QUIT, End, Cancel, Arret or Unsubscribe: turns ALL phone notifications off.
  • ON username: turns on notifications for a specific person on your phone. Example: ON alissa
  • OFF username: turns off notifications for a specific person on your phone. Example: OFF blaine
  • FOLLOW username: this command allows you to start following a specific user, as well as receive SMS notifications. Example: FOLLOW jerry, or f jerry for short.
  • LEAVE username: this command allows you to stop receiving SMS notifications for a specific user. Example: LEAVE benfu, or l benfu for short.

Additionally, you can set your “Sleep Settings” in your web profile to silence mobile updates for certain periods of every day. This is highly recommended for those who enjoy undisturbed sleep, as getting updates from Twitter on your phone in the middle of the night is annoying, to say the least.

To use Twitter from your phone, you can also download the official Twitter app for iOS devices from the App store, for Android phones from the Market, or for Windows 7 phones from the Windows market. Other third-party Twitter apps are available for smartphones as well, and either these or the official Twitter app will allow you to use Twitter from your phone.
