O2 UK has announced the launch of an HSDPA option for residential customers, making it the last of the British wireless network operators to launch the 3.5G mobile broadband offering. The high speed service is being offered to all existing customers for GBP20 (USD40) per month which includes 3GB of mobile data. O2 has offered mobile data cards to business customers for over a year, but this latest move sees it enter the burgeoning consumer ‘dongle’ market. Customers choosing to sign an 18-month contract will be given a dongle, a USD modem device, free of charge, while those preferring to pay the monthly charge on a rolling month-by-month basis will have spend GBP120. Mobile Broadband customers will also be given free access to 7,500 Wi-Fi hotspots on The Cloud network. Speeds of up to 1.8Mbps are currently available over the 3.5G infrastructure, although this will be upgraded to 3.6Mbps in June.
