PAYG from today - 3p/minute, 2p/text, 1p/MB
If you are a heavy data user, this is probably still not very cheap but you no longer have to "buy a bundle" to get low prices (compared with most PAYG pricing, where mobile to mobile can cost up to 50p/min, texts 12p... Knocks spots off even Asda which had a 'Which?' best value award a couple of years ago.)
