Consumers can receive special introductory discount when taking out a T-Mobile dongle subscription on an 18-month contract.
For consumers seeking mobile broadband services through the internet service provider, the current pay monthly deal offers a third of their standard monthly bill.
T-Mobile has reduced the price of its Mobile Broadband USB stick 610 contract – which comes with an unlimited data allowance – from £15.32 per month to just £10.21.
The ISP said this allows consumers to get their hands on "fantastic value mobile broadband".
It added that the dongle is both PC and Mac-compatible, and users have the option of adding a 4GB memory card to store photos, files and music.
"The USB Modem Stick lets you download at speeds up to 7.2 Mb. It's also nippy if you need to swap files between PCs, Macs and phones. Just slip a microSD card into the slot - it'll take up to 8GB," T-Mobile explained.
"And getting online couldn't be easier. Simply plug the USB Modem Stick into any USB port. Then enjoy fast, reliable mobile broadband that covers a whopping 80 per cent of the UK."
