The Galaxy S8 might be the smaller of the two, but it still has a huge display and a truly stunning design. For those sorts of looks, you’ll need to spend big. There’s no right or wrong way to finance such a purchase, but the usual rules apply — skimp on the upfront payment and you’ll have to pay more on the monthly plan, and vice versa. Three has some of the cheapest monthly plans, however the lowest, at £35 per month, only comes with 500MB of data. Hope you don’t like streaming on the go…

If you want go SIM-free, you’re best bet is probably to buy from Samsung direct. A few retailers such as Carphone Warehouse and Buymobiles are stocking the phone, but their prices are pretty much the same. At £689, it’s an expensive phone, but you do have the option of financing it on a monthly basis through Samsung’s Upgrade Programme.

The larger Galaxy S8 Plus obviously demands slightly deeper pockets. It is, however, one of the best phones that money can buy, so unsurprisingly it has a price-tag to match. There aren’t too many deals to be had, but we like the one O2 offers for £42 per month, with unlimited texts, minutes and 500MB of data. If you’re willing to spend a little more, you can double your monthly data cap for £46 per month, or grab 3GB for £49 per month.
