Latest reviews and articles:
The Samsung Galaxy A5 2017 is a beautiful phone that's been over-priced. On monthly contracts, it will cost around the same as the Galaxy S7, but this is not a flagship phone. Wait for the price to fall to around £20/month, and you'll get a stunning phone with a sharp screen, fast processor, and plenty of memory.
The Samsung Galaxy A3 (2017 edition) is a compact and slim smartphone with a beautiful unibody design. With a decent processor, excellent screen and good camera, only the battery life is below average. But we feel that at £25/month on Pay Monthly, the phone is over-priced.
USSD (Unstructured Supplementary Service Data) codes are used in GSM phones to retrieve data from the service provider (EE, O2, Vodafone, etc.) USSD codes are commonly used to find out information about the phone, check account details, balance, usage, online banking, and other network services. They are sometimes called "secret codes".
The LG GBB60PZGFB is an unusually tall freestanding fridge-freezer with a gloss metallic finish. It's frost-free with a practical interior layout, and good value too. But what really makes this model stand out is its exceptionally efficient and quiet linear compressor, which achieves an unprecedented A+++ energy rating, making it the best energy-saving fridge-freezer that we know.
The Sony Xperia XZ is Sony's flagship phone for 2016. Slim and sleek, the XZ is a premium-build device running Android M and featuring a fast Snapdragon 820 processor with plenty of memory. Photography is a key strength too, thanks to its 23 megapixel camera with laser autofocus.
Plusnet is a UK-based broadband and phone provider, offering either standard or fibre broadband internet, including phone calls. YouView TV and BT Sport Lite are also available to broadband customers. On 29th November 2016, LIFE Mobile customers joined the Plusnet family and became Plusnet Mobile customers.
The Huawei Nova is a top-rated mid-range phone. With a premium-design metal body, it has the look of a high-end handset but for half the price. Its top features are its 5-inch high resolution screen, fingerprint scanner, fast 8-core processor, and very long battery life.
The HTC One A9s is a top mid-range phone, with an attractive slimline all-metal build. The 5-inch HD screen looks good, and the phone takes good pictures with its HDR cameras. Performance from the 8-core processor is strong, and battery life is reasonable too. Priced for value, this is an excellent buy.
