The Nokia 3620 and Nokia 3660 are smartphones that succeeded the Nokia 3600/3650. Both run on Series 60 version 1.x on Symbian OS. They were introduced on October 9, 2003.[1]

Changes from the 3600/3650 include a conventional keypad (as opposed to the 3650's circular keypad [1]), and a 16-bit display (as opposed to the 3650's 12-bit display).

Both the 3620 and 3660 are basically the same phone, except that the Nokia 3620, being targeted at the US market, operates on GSM 850/1900, while the Nokia 3660, a European phone, operates on GSM 900/1800/1900.

They use an ARM compatible main CPU (ARM4T architecture) running at 104 MHz.

In the United States, the 3620 was carried by AT&T Wireless and Dobson Communications, while the 3660 was carried by T-Mobile USA.

The replacement for the Nokia 3660 is the Nokia 3230. The 3620 does not have an official replacement, although it was replaced by the Nokia 6620 in AT&T/Cingular's lineup after the merger between AT&T Wireless and Cingular.
