Vodafone UK on its forum has sent notice that it will start charging for data over 500MB on its network. Starting June 1st, the carrier will still supply 500MB of data with any bundle plan worth £25 or higher but will pay an extra £5 for every 500MB they use over that threshold. It had previously put a 500MB "fair use" ceiling on these plans but didn't charge for it or throttle use unless it created a significant problem on the network.
