No, no - no, no, no, no - no, no, no, no - no, no, there's no limit. Ahh, Three Unlimited - one of Pocket-lint's favourite Eurodance/Hi-NRG acts from back in the day, or something like that.

And a perfect intro for a story about Three extending its unlimited mobile data across all of its contracts, meaning that for an extra £3, anyone can tap into the unmetered access that The One Plan customers get.

Starting on 7 October, the extension means that unlimited data bundle contracts are available from just £18. For that you'll get yourself involved in one of the new Talk & Text plans.

Think you don't need all that mobile data? Think again - Three has revealed that the average quantity of data its iPhone 4 customers were using in February was 488MB per month and, by August, that number had risen to almost 1.2GB.

"This is a bold, but clever move by Three - and further evidence of the speed at which the smartphone market is evolving," said Ernest Doku, technology expert at

"Unlimited data for less than the price of a posh sandwich would have seemed unthinkable just a few months ago.

"By bringing the price of mobile internet down so dramatically, Three aims to give price-savvy shoppers a genuine choice between pay-as-you-go and monthly contracts."
