The company's new piece of hardware will cost £39 and is offered with an initial £15 worth of credit.
Vodafone's dongle will allow for 1GB of data - equivalent to 30 hours of web surfing.
Conversely, users can send 650 emails or download the equivalent to 65 music tracks, at a rate of between 1-2Mb.
Users are not tied to a single computer and can use the dongle in any PC USB port.
Unlike other mobile broadband dongles, the Vodafone modem will not expire if a top up is not provided within an allotted time - although there is a minimum top-up fee of £15.
The dongle can also be used as a Flash drive, storing up to 4GB of files.
Vodafone's new dongle follows the launch of its Stick Pro at the beginning of last month, offering download speeds of up to 7.2Mb
