If your PAYG phone has a web browser, you just browse away and Orange will deduct £2 per day (more if you exceed 25 megabytes, less if you only download a trivial amount).

To reduce this cost, you can buy an "extra" which deducts an amount from your PAYG balance in advance. For £1 you get all-day access (25 megabytes maximum), or for £5 you get access for a week (25 MB per day maximum).

The details are here:

You can buy the bundle from the phone by voice (I seem to recall the number is 453 and you need to go through many levels of nested voice menus), or by the phone's browser from the Orange start-up page, or from the Orange website if you've registered your device and set up an account with their website.

The words to search for are "Orange World". Not an intuitive name for "Mobile Web Access" is it? I guess the name is a remnant of their attempt to set up a "walled garden" for their users.
