This is the official Nokia 1606 User Guide in English provided from the manufacturer. If you are looking for detailed technical specifications, please see our Specs page.
The 1606 is the entry-level model, and lacks camera. The design again is very similar to the 3606, but the front shell only has a simple greyscale landscape display. The keypad is almost the same also, but with dividers between the keys. Though not unique but helpful is the built-in LED light on the hinge which is activated by a button on the front shell, above the screen.
