Each of the three is priced at £379.95 ($619 USD) off-contract. On the other hand, if you sign up for a plan costing £21 ($34 USD) a month or more, the phone is free. Carphone Warehouse suggests the plan from Vodafone which gives you 300 minutes, unlimited texts and 250MB of data monthly for £21 a month. Not only does that include the phone for free, it also includes a free mini flip cover for the device. For those of you in the states feeling some pangs of jealousy, the pink model is heading to AT&T.
As far as the innards of the phone are concerned, the purple, orange and pink versions of the Samsung Galaxy S4 mini are exactly the same as the more mundane black and white models.
