The retailer is the only place that customers can get the Xperia Z3 Compact in green as well as the regular colours of black, orange and white with a variety of options both on contract and SIM-free.

Users interested in the Xperia Z3 can get the handset for as little as £38 per month with no upfront cost on O2, which brings unlimited minutes and texts plus 1GB of 4G data, and it costs £549.95 SIM-free.

The Xperia Z3 Compact, meanwhile, can be ordered for as little as £28 per month with no upfront cost on O2 and that tariff includes 500 minutes, unlimited texts and 500MB of 4G data, with the device costing £429.95 SIM-free.

Both handsets were announced at the recent IFA 2014 show in Berlin and the larger of the devices is already being dubbed an iPhone-killer in certain circles thanks to an impressive list of specs that is led by a 20.7-megapixel camera that has autofocus, LED flash and is designed to work well in low light conditions.

Inside the case there is a Qualcomm Snapdragon 801 quad-core processor clocked at 2.5GHz and supplemented by 3GB of RAM, the same 5.2in full-HD display of its predecessor and it is water and dust proof.

The smaller Xperia Z3 Compact, meanwhile, has a similar set of tools to its larger sibling except for a 4.6in screen that has a 720p resolution.
