The C3 is a consumer smartphone that tops out on EDGE speeds, but can connect to WiFi. As a messaging phone, it will replace the E63 smartphone and be competitive against the EDGE-only BlackBerry Curve on the GSM network. The device, like the Microsoft KIN, will feature access to social netoworking. The C3 will also feature free turn-by-turn OVI Maps, Opera Mini, 3.5 mm headphone jack, and support for up to 8 GB of removable memory. Like the E72, E71, and E63, the C3 will feature a QVGA non-touch display supporting up to 262,000 colors.

The device will run the Symbian OS, though not Symbian^3 nor Symbian^4.
