The Nokia 3110 was announced at the CeBIT exhibition in Hannover, Germany in 1997. It was the first Nokia to feature the Navi-Key menu navigation system which was developed by Nokia employee, Christian Lindholm.
The Navi Key was the large button immediately below the screen and its function varied depending on the text displayed above it. Nokia claimed that the 3110 offered "the ultimate ease of use with a unique one-key access to functions".
Initially the "C" key functioned as an "Exit" key in the user interface logic. This proved intuative to novice users but was confusing to experienced Nokia users. In a later software release this was changed to "Back" and then "Exit" with a long press.
The monochrome screen could display 4 x 13 characters with variable font size.
The phone book could store up to 250 telephone numbers and associated names using the SIM card. Speed dialling was provided for nine of these entries using keys 1 to 9; you pressed the key once and then the Navi-Key button to make the call.
Alternatively, one touch dialling was available for eight entries by holding down key 2 to 9 and this automatically called the number associated with the relevant button The use of key 1 in this mode was reserved to call the network service provider's voice mail service.
The Nokia 3110 supported SMS text messaging, call registers recorded the five most recently dialled, received and missed calls and call timers recorded the duration of the last dialled or received call together with a cumulative total. In addition you could personalise the phone by selecting one of the 25 preloaded ring tones.
The 3110 was built on the same "platform" as the
Nokia 8110 and it used the same accessories.
