Mobile operator 3 has extended its all-you-can-eat data offering to all customers for an extra 3 a month.
It builds on two announcements in the past year from 3 - The One Plan contract, launched in December 2010, and a 15 bundle deal including unlimited data for PAYG customers, introduced in March 2011.
The all-you-can-eat option will be made available on all contracts from 7 October, with deals starting at 18 per month.
Our customers tell us that their use of data goes up significantly over the lifetime of their contracts, as they do more and more with their handset.
"The One Plan quickly became our number one contract tariff and our all-you-can-eat PAYG offer is our most popular bundle," said Thomas Malleschitz, marketing director at 3 UK.
"Our customers tell us that their use of data goes up significantly over the lifetime of their contracts, as they do more and more with their handset. All-you-can-eat data means that they don't have to worry, they can have that peace of mind for the long term on a contract of their choice."
Spectrum warning
Meanwhile, 3 has warned it may run out of network capacity in urban parts of the UK if the Ofcom-organised spectrum auction next year.
Chief executive David Dyson warned rivals may be trying to delay the auction as it would benefit them.
"There is a huge financial incentive for rival operators to delay the auction," Dyson said during a press briefing, according to reports. "We are worried that the other three will attempt to squeeze us out of the market."
O2 and Vodafone have raised issues with the auction, questioning its legality under UK law.
The auction has been pushed back by a quarter at least to the second quarter of 2012, after Ofcom failed to deliver the terms of the spectrum sell-off this month.
