Consumers signing up for a 1GB per month T-Mobile dongle can get a free USB modem from the internet service provider.
T-Mobile provides the Mobile Broadband USB Stick 620 at no extra cost when internet users sign up for its £10 per month plan on an 18-month contract.
The mobile broadband deal may be ideal for consumers who wish to browse the internet and check their email on a casual basis.
However, T-Mobile warned heavier data users - such as those who enjoy downloading films and music - that they may be better off signing up for a broadband package with a higher monthly usage allowance.
The USB Modem Works with Windows 7 and Mac software, meaning both Microsoft and Apple customers alike can take advantage of the 1GB mobile broadband deal.
Users are able to store photos, music and files on the USB Modem courtesy of an 8GB memory card.
T-Mobile also offers pay-per-day options for infrequent dongle users, allowing them to pay £2 for 24 hours' worth of internet access every time they wish to access the web.
