There are similar functions between the K750i and K550i, but the latter is more advanced and economical to use. This phone is available in two colours, black and pearl white. Both the models look equally attractive and sleek. The phone is not very big in size therefore it is easy to handle it or simply just slip it in your pocket. The keypad of this phone is similar to the W880i, the alphabets are written above the keypad. The dark blue back light illuminates the keys well.

The phonebook has the capacity of 2500 contacts and you can sign five phone numbers to one contact. The phone book capacity is enough for even the most active user because only about 500 entries are recorded at the most.

The messaging tools are similar to most of the common handsets. The smiling faces that are used to insert while sending a message are improved. MMS and Email functions are upgraded as well.

The phone can edit music files using a soft ware named Music DJ. It can also be used to create ringtones. There is an advanced version of this software called the Video DJ. It can save files of the 3PG format. Along with these soft wares there is another one called the Photo DJ. You can edit photos taken from the camera. This is a very impressive function.

This phone features a 2MP camera with auto focus and built in flash. The camera is almost similar to the K750i, but its look has been given a face lift. Overall this phone is economical and provides all the functions at the same time.
