The Sony Ericsson K600 is a 3Gmobile phone handset manufactured by Sony Ericsson. It was announced in the first quarter of 2005. The K600i is its international variant. Generally available on the Orange network in the UK, the K600i is very closely related to the K608i and V600i models, and was produced at the same time. The K608i was available on the 3 network, and the V600i was available on the Vodafone network. The K608i and V600i are both practically the same phone internally as the K600i, but look different externally.
The K600 was relatively small for a 3G phone at the time of its manufacture. As the phone doesn't feature a memory card slot, it is mainly criticised for its inability to expand memory. It is usually praised for its connectivity options, it can serve as a modem for a computer either via USB data cable or Bluetooth.
