O2 and Vodafone reveal their iPad data pricing

Following Orange's pre-emptive iPad plan pricing announcement on Friday, O2 and Vodafone have also revealed how much they will charge for data use on Apple's tablet.

O2 will charge £2 a day for 500MB of usage, £10 a month for 1GB and £15 a month for 3GB. Vodafone will also charge £10 a month for 1GB and will ask for £25 a month for 5GB. All the monthly plans are on a rolling basis, with no long-term contract required.

To recap, Orange will charge £2 for a day's usage up to 200MB, £7.50 for a week's usage up to 1GB, £15 for 3GB a month, or £25 for 10GB a month. Therefore, O2 appears to offer the best value for on-the-day usage, O2 and Vodafone are neck-and-neck for the average user's needs, and Orange is the go-to operator for the heavy user.

These are the three operators that have formally announced iPad price plans, and that will be carrying the new micro-SIM format that is needed to provide 3G access to the device. However, as has been recently demonstrated, anyone with a sharp blade and a keen eye can cut any normal SIM card into the micro-SIM's dimensions, as the iPad is unlocked.
