The Nokia 3595 is an entry-level mobile phone with a Nokia Series 30 96 x 65 color user interface. It operates on North American GSM-1900 and GSM-850 networks. GPRS is used for data transmission and mobile Internet WAP service. Users can download Java applications, background images and polyphonic ringtones. The phone supports SMS and MMS messaging, and includes an IM client for AOL Instant Messenger and ICQ in the latest firmware revisions. The 3595 is of the DCT4 hardware generation. The European / Asian equivalent to the 3595 are the Nokia 3510i and the Nokia 3530, which operates on GSM 900/1800, and features a more conventional keypad. It should be noted that the 3595 and 3590 faceplate and keypad buttons are interchangeable.
Prior to the release of the 3595, the Nokia 3560 was released, with a more standard arrangement of the keypad, and operating on TDMA and AMPS for roaming. IS-136. The 3560 was released in the Spring of 2003 and was sold through early 2004 when TDMA accounts were no longer being activated. The 3560 came with more preloaded content than the 3595 since the phone was primarily designed for prepaid TDMA customers. The 3595 contains less preloaded content but enables users to download new content using GPRS, or MMS. The 3595 is often though of as the GSM equivalent to the TDMA 3560, although it is actually an upgrade to the Nokia 3590 handset.
A newer version of the 3595 is the Nokia 6010, which improves on the keypad and gives the phone a more business-oriented look. The 6010 also has corrected all of the software bugs that were previously found in the 3595 handset. The 6010 was discontinued by all major GSM carriers except T-Mobile in 2006. T-Mobile will likely discontinue the 6010 by the end of 2006 or early 2007, although the handset is still popular amongst consumers who desire a user-friendly handset without expensive features.
