O2 has announced that its UK subscribers will be able to receive tweets by text for free from the start of August.
From that point, users can turn on text notifications on the popular micro-blogging site, and receive replies and direct messages for free as texts.
Users will be able to post their own tweets via text too, although as part of their normal text message bundle, or for the price of a normal text.
Twitter turned off the option to receive tweets by SMS last August, saying it was costing the company too much to send them. Instead, it's looking to make deals with operators, like this one with O2.
O2 says it has a fair usage policy in place, though: users have got to try to stay below 600 messages a month - meaning just 20 a day. Not such great news for heavy Twitterers.
The deal with Twitter joins existing O2 partnerships with Facebook and Bebo. "We believe that mobile will soon become the most popular way of accessing social networking sites, giving real time access to tweets and status updates wherever you are," says head of content Antony Douglas.
"The agreements we now have in place with Twitter and the other key sites brings this a step closer."
