TalkTalk has reintroduced the unlimited usage allowance for its entry-level Essentials home phone and broadband package.
Previously, subscribers have been limited to 40GB of data per month, but there will now be no specific cap on downloads, reports ISPreview.co.uk.
Only persistent heavy downloaders - those who breach TalkTalk's fair usage policy - will be penalised for their usage.
The reintroduction of an unlimited usage allowance is likely to boost the popularity of TalkTalk Essentials, which is currently priced at £3.25 for 12 months.
The broadband deal - available on a 12-month contract - offers download speeds of up to 13Mb and a free wireless broadband router.
Customers also receive HomeSafe online security, allowing parents to set up web controls and blocks.
Essentials subscribers receive inclusive evening and weekend calls to UK landlines and 0845/0870 numbers, and unlimited calls to other TalkTalk-members
As an added bonus, they are also entitled to ten per cent off the 16 phone numbers they call most frequently.
Households seeking anytime home phone calls may be better off signing up for the higher-tier TalkTalk Plus broadband package.
The deal offers up to 13Mb download speeds, an unlimited monthly usage allowance, a free Wi-Fi router, free security and unlimited calls throughout the week.
Customers receive a 50 per cent discount for six months, enabling them to pay just £7.25 per month for unlimited broadband and calls.
Both TalkTalk Essentials and TalkTalk Plus subscribers are required to pay a line rental fee of £14.50 per month, reduced to £9.50 if they pay a year in advance.
