As the HTC One X's European release approaches, we're seeing Euro carriers ramp up their promotion of the device. Vodafone UK is now listing the One X in white and grey, and offering both for free on two-year contracts of £41 or more per month. That'll get you the phone, 900 minutes, unlimited texts and 1GB of data. If you're looking for a lower monthly bill, it's also possible to bag a One X for as little as £26 per month, though you'll pay £299 up-front for the privilege.

The One X's little brother, the HTC One S, is also up for pre-order, and free from £36 per month (that's with 600 minutes, unlimited texts and 1GB). There's no word on Pay As You Go prices, as Voda typically limits its PAYG offerings to low-end devices.

While rival networks aren't revealing their price plans for the One X or One S just yet, Three, O2, Orange and T-Mobile all offer registration links, where customers can sign up for more info as it's available. Retailer listings suggest the One X will sell for just under £500 SIM-free, while the One S is expected to cost around £450.
