T-Mobile is offering unlimited mobile broadband for £15 a month to customers who sign up before the end of March.
Subscribers to the Web'n'Walk Plus price plan will also receive a free wireless USB modem, which allows high-speed internet access using T-Mobile's cellular network.
Customers will also have free access to the company's extensive number of Wi-Fi hotspots. There is also an unlimited usage allowance, meaning that customers will never pay more than £15 a month to use the service no matter how much they use the internet.
Web'n'Walk Plus is available at the reduced price for a limited time period only, with the offer ending on March 31st.
The deal is available to those signing up to a 24 month contract.
Mobile broadband is becoming an increasingly popular option for those who want internet access on the move, with a number of internet service providers expressing their commitment to providing such offerings at the recent Mobile World Congress.
