Fantastic handset, only just got it but after playing with it for a couple of hours...IM IMPRESSED BIG TIME. Its absolutely tiny and weighs nothing...what a great phone. RECOMENDED HIGHLY 10/10.

I decided on the Samsung SGH-Z400 when I was looking for a replacement phone as my contract had come to an end. I had been pleased with the one I had as it was fairly bullet proof & did everything I needed. I read a number of reviews on different phones & decided to order the Samsung D500 as it appeared to be reasonably reliable. Sadly, however, the operator at O2 said that they had discontinued the D500 but recommended the Z400i. As I was fairly indifferent about it all I agreed to give it a go.

Overall, I was pleasantly surprised & feel that it provides a good alternative to my Nokia 6320i. I would recommend this phone to careful individuals who need a reliable phone with good call quality that offers a good range of features & a reasonable degree of personalisation. It has lots of toys to play with, but if you are a total gimmick-freak & you want a 'swiss-army knife' phone then look elsewhere.

I upgraded to the Samsung SGH-Z400 when I renewed my contract. It looks like my old Samsung D500, but it has loads more features. There's a 2 mega-pixel camera, a 2 inch screen and an MP3 player, as well as bluetooth so I can transfer stuff from my laptop. It's brilliant. I like Samsung mobile phones because they have great battery life, and they are pretty intuitive to operate, and as far as I can tell so far, this phone is no different. My only gripe is I'm a girl, and this is a pretty masculine phone. I have small hands, small pockets and small handbags, so I'd rather be carrying something the size of the E350. Hopefully they'll manage to get the features of this great phone into something smaller for us girls so we don't have to carry around a rucksack and a brick when we go out.
