Here's a good deal for anyone who wants a mobile phone that they can easily type email and text messages on without paying a fortune. Samsung's C6625 smartphone has a full QWERTY keypad, rather like the ones found on older Blackberry phones, and yet today you can buy it for less than £100 - and that's SIM free, ready to use on any mobile phone network.

The C6625 runs the Windows Mobile operating system and has a large 2.6in colour screen. It has a fast HSDPA internet connection and a 2-megapixel camera for snapping photos. It can play music and video files, and if there's not enough storage space inside for all your media files you can add more with a memory card. Click the jump for details on how to buy one.
