O2 and Vodafone announce their iPad 3G data plans

Apple started taking pre-orders today for the iPad Wi-Fi and iPad 3G in the UK, and tariff prices for the 3G model have also gone on display.

Orange had already announced its iPad data plans - 1GB per week for £7.50, 3GB per month for £15, and 10GB per month for £25.00 - and now O2 and Vodafone have waded in with their price plans.

O2 has both a per day and per month set-up available.

£2 a day will bag you 500MB limit each day, then there are the monthly options - £10 a month for 1GB, and £15 for 3GB.

All three options come with unlimited wi-fi at hotspots (although this is subject to a fair usage scheme).

It's worth noting that these data plans don't have a roll-over system. In other words, if you don't use the whole 500MB in a day, you won't be compensated for the remaining data.

Vodafone's prices are rather steep in comparison. There's no daily rate as of yet, and the monthly price plans are more expensive than its competitors.

250MB will set you back a massive £10 a month, while the 5GB a month plan is £25 a month.

This means O2's 500MB per day for £2.00 is the cheapest day rate, while Orange's 10GB for £25 is the cheapest monthly rate, at least in terms of data for cash.

Details on all the tariffs can be found in the UK Apple Store.
