The phone can send and receive text and multimedia messages with ringtones and images in BMP, JPEG, PNG and GIF formats. The basic 3100 does not have any voice recorder, radio receiver, MP3 player or camera, while the 3100b version supports voice recording. A camera can be added to the phone via its Pop-Port.
This was one of the most popular Nokia phones in Europe and United States.
In 2004 Nokia released the Nokia 3120 phone, which is cosmetically different from the 3100 in having a new metallic effect covers and a revised keypad. The 3120 essentially shares the same platform and form factor with the 3100, other than the aforementioned faceplate.
The Nokia 3200 builds on the features of the Nokia 3100, and incorporates more features from the Nokia 7250i, such as a built-in CIF-resolution camera.

The CDMA version of the Nokia 3100, working in CDMA2000 1xRTT networks. It is physically similar to the 3100 except for a built-in flashlight and a slightly different shape of the rear battery cover; the phone's firmware is more feature-rich than the basic 3100 or 3100b (e.g.: voice tags and voice commands, Organizer menu, etc.)
The Nokia 3105 was used in Australia on the Hutchison Orange network until the closure of the CDMA network in Australia in late 2006. All customers on the Orange network were then moved to Hutchison's 3G network "3".
