O2 is only offering its three months' free broadband deal for one more week.
Customers in the UK looking to switch to the broadband provider have until May 31st to take up the deal, which is available to those who also sign up for the company's new home phone services.
Available on a minimum 12-month contract deal, the package includes access to speeds of up to 24Mb and a free wireless router.
Unlimited evening and weekend calls are also included in the deal, which is only available online and reverts back to its regular price of £9.50 a month.
O2 recently launched its new Niggles and Narks advertising campaign, which is designed to highlight how consumers can forget about common complaints by switching to its services.
Research was published to coincide with the launch of the promotion and revealed that 41 per cent of people regard slow internet connections as their biggest daily frustration.
