T-Mobile has announced that it will introduce a 3G service to the UK in May.

Initially the service, which offers download speeds of up to 384Kbps, will be accessible by corporate customers using a laptop PC card.

But the operator revealed that it also has a portfolio of handsets in the pipeline, including the Nokia 7600 which supports its Mobile Jukebox service and the viewing of video clips, and the Sharp TM100, which features a 't-zone' button to launch the operator's mobile portal.

The devices will automatically select the quickest network available depending on coverage, and either General Packet Radio Service (GPRS) or Universal Mobile Telecoms System (UMTS) or, in the case of notebooks, Wi-Fi.

"The new network is yet another vital building block in our multimedia network," said René Obermann, chairman of T-Mobile, in a statement.

"We will help our customers choose the optimal technology to suit their individual needs by providing innovative terminal equipment and services.

"Our target is easy-to-use, seamless communications. This is why we offer our customers services based on GPRS, UMTS and wireless Lan."
