Vodafone has cut the price of its mobile broadband USB modems by £50 for users on 30-day contracts.

Following a similar move by 3 last month, Vodafone has reduced the price of its broadband-on-the-move modem stick from £99 to £49.

Contracts currently start at £15 a month for 3GB of usage on a 12-24 month period going up to £25 a month for 5GB on a 12-24 month deal, while 30-day contract users pay £20 a month for 3GB of usage.

Vodafone launched its first USB modem, the Mobile Connect USB, in November 2006. The device was hailed as a breakthrough for combining online-anywhere performance offered by PC Cards with the flexibility of USB.

Last month 3 cut the price of its £99.99 ZTE and Huawei E220 modem dongles to £49.99 on pay-as-you-go deals.
