If you already have a Twitter account, you can access it from your phone using SMS or Twitter's mobile website, mobile.twitter.com. You can also create a new Twitter account via SMS by sending the word START to your Twitter shortcode.
Twitter is a free service; we do not charge you to use it, even via SMS. However, if you use Twitter via text message on your phone, your mobile carrier may charge you for those messages according to your service plan. Read more here.
These are phone numbers that are used by Twitter to help you access your Twitter account via SMS on your phone. You can text message your Tweet to your respective code/number and it will post to your Twitter profile. Different countries use different codes. Find yours here!
Yes. When you've attached your phone to your Twitter account, you will only receive updates from friends you've asked to get mobile Tweets from (learn about this here). When you send a text message from your phone to your Twitter code, it will always post as a Tweet to your profile.
Turn off mobile updates from users you follow in one of these ways:
If you have a smartphone that supports an official Twitter app and are receiving two sets of notifications (one through SMS and one through the app's push notifications) you may want to disable your SMS notifications. To do this, send OFF to your Twitter short code. Now you will only receive one set of notifications!
We have short codes for many countries and carriers - texting one of these will allow you to Tweet via SMS. If your country is not listed there, you might want to use our one-way long code to post content to Twitter. Please note that all subscribers (even in the UK) may be charged international message rates.
You can also go to our mobile website, mobile.twitter.com from your phone's browser no matter where you are in the world (as long as you have cell reception on your smartphone!).
Unfortunately, Google Voice doesn't allow messages to or from the US short code (40404) so we're unable to link your Google Voice phone number to a Twitter account at this time. We're working toward making this a possibility soon, and we appreciate your patience in the meantime.
