The chief executive of Nokia expects replacement handsets to make up 80% of the Finnish mobile communication giant's sales next year, with wireless application protocol-enabled (Wap) phones leading the way.
Jorma Ollila predicted that as interest in wireless access to the Internet grows, Nokia would double its handset sales.
The company said it has sold 78.5 million of the 275 million mobile phones produced last year. Its closest rival, Motorola, sold some 50 million.
Nokia launched its 7110 Wap-enabled phone which costs about £130 each, last November. The Nokia handsets, however, have been in short supply despite the company claiming to be shipping "hundreds of thousands".
BT Cellnet has also begun offering a Wap service for the 7110 handset. Ericsson is expected to launch its first Wap handset in Britain in the next few months.
Siemens, Philips, Samsung and Mitsubishi are also thought to be working on similar handheld Wap devices.
