The Nokia 7110 is a GSM mobile phone announced in February 1999 and released in October 1999.
The 7110 was Nokia's second handset with a sliding cover that could be used to answer and terminate voice calls.
As with the 8110 before, with the cover deployed, the microphone was brought closer to the user's mouth, improving the clarity of the voice reception.
Connectivity is provided via a standard IrDA transceiver on the top edge of the handset.
The navi-roller was used in place of the familiar up and down buttons, allowing the user to rapidly scroll through lists of options; depressing the roller selected the currently highlighted option.
