First Twitter turned off SMS notification in the UK…
Then they turned it back on for Vodafone subscribers in the UK.
Now they have turned it on for O2 subscribers too.
Full, two-way interaction with Twitter over SMS is now available for everyone who uses O2, the largest mobile operator in the UK.
Easy to set up
To Twitter over SMS with your iPhone or any other mobile, head over to your account settings and activate your device. The Twitter shortcode in the UK is 86444 if you want to save it in your address book.
Not sure impact on me as the iPhone and Twitterific makes it very easy to keep in touch with Twitter. However if you have a “standard” phone, or a phone without a data contract for the web, then this does make sense and will be useful.
