Twitter introduced a new feature called Fast Follow, that allow users to follow twitter users without creating a Twitter account. Anyone in the USA can receive Tweets on their phone even if they haven’t signed up for Twitter.
For example, let’s say you want to get Tweets from New York City’s office of emergency management (@NotifyNYC). Just text ‘follow NotifyNYC’ to 40404 in the US.
Set SMS alerts: From your computer, wherever you see a user on Twitter.com, you can hover over their name or avatar, and click on the phone icon that appears in the hovercard. Whenever they tweet, you’ll get it as an SMS message on your phone.
It’s just as easy to set alerts from your phone. Send ‘on [username]’ or ‘off [username]’ to 40404 in the US. (Tip: Check our list of numbers for each country and add the Twitter number to your address book.)
