Unlimited broadband provider O2 has made moves to clarify its current usage policy.
The broadband deal provider's BT Wholesale-based Home Access packages were marketed as coming with unlimited downloads, however, the firm is urging users to abide by its traffic management and usage restrictions to avoid being blocked from accessing the broadband offers.
O2 has already contacted a number of its heaviest users with its current broadband internet restrictions, which it says are not new.
The firm said that while users are entitled to unlimited broadband downloads, they must use the services provided within reason.
O2'S usage policy states: "Our network's been designed to cope with people downloading large files (like music or films) and watching video online.
"But if you're using the service excessively - like continually downloading large files at peak times - then we do reserve the right to warn you to lower your usage."
Recently, O2 research showed that two-fifths of customers find slow broadband packages and not download limits most frustrating.
