OnePlus's first UK carrier partnership kicks off sales from September 29.

OnePlus is best known for direct-to-consumer sales at low prices, but in the past year it's started teaming up with select carriers, like Finland's Elisa, with strong sales resulting. And now the company has partnered with O2 in the UK to get its latest handset, the OnePlus 3, onto store shelves. Sales kick off from September 29, with prices starting at £28 per month on O2 Refresh.

The OnePlus 3 is available on a range of O2 Refresh tariffs, offering from 500MB to 20GB data. Tariffs include £28 per month for 500 minutes, unlimited texts and 500MB of data, and £35.50 per month for unlimited minutes, unlimited texts and 3GB data. Both tariffs come with no upfront payment.

In today's press release, OnePlus co-founder Carl Pei talked up O2's history of focusing on premium handsets and tech-savvy consumers:"We chose O2 as our exclusive partner in this important market because they have a history of focusing on the most premium smartphones for the most savvy users, which aligns very well with our products and users."

It's possible Pei was referring to O2's history with Apple: O2 was the first UK operator to partner with Apple to launch the original iPhone in the UK back in 2007, and exclusively carried that phone for more than two years.

The OnePlus deal isn't of the same scale as that, of course, but there's no denying the OnePlus 3 has made a splash since its debut earlier this summer. In our review, Andrew Martonik said, "OnePlus is finally ready to join the big leagues with the OnePlus 3. Gone are the days of justifying missing features with a cheap price, and no longer can we give it a pass for its upstart-style of operation. The OnePlus 3 is the real deal, ready to be compared and evaluated as the flagship phone that it is."

To celebrate the launch, there'll also be a OnePlus pop-up event on launch day from 10 a.m. to 10 p.m. at O2's Westfield White City store in London. A full list of price plans will go up on O2's site from September 29.
