Samsung Galaxy S8 | £149 upfront | 16GB data | Unlimited minutes and texts | £40pm
This is probably the deal we'd go for on Vodafone this month. 16GB seems like the sweet spot for the S8 on this network. 16GB is enough data for most people and while you can get 32GB for a bit more, this is probably the time to stop going up in price. Total cost over 24 months is £1109

The 2 best Samsung Galaxy S8 deals on O2

Samsung Galaxy S8 | £150 upfront | 3GB data | Unlimited minutes and texts | £32pm
This option from O2 is the cheapest Galaxy S8 deal out there on any network at the moment. All told it's a pretty good deal when compared against all the others. You pay £125 which is about average for the launch deals, but the monthly is lower than average - £35 per month for 3GB and unlimited calls and texts. It's a good balance and works out cheaper even than deals with less data. Total cost over 24 months is £918

 The 3 best Samsung Galaxy S8 deals on Vodafone

Samsung Galaxy S8 | £13.99 upfront | 1GB data | Unlimited minutes and texts | £36pm
This is the cheapest Galaxy S8 deal on the Vodafone network and it comes courtesy of Mobile Phones Direct. It's only 1GB you get with this, but the just-reduced £13.99 upfront fee and £36 monthly cost make it relatively attractive. But it's not the deal we'd go for. Total cost over 24 months is £877.99

Samsung Galaxy S8 | £199 upfront | 4GB data | Unlimited minutes and texts | £38pm
This is a step up in value versus the best 1GB deal on Vodafone - for just a bit more over the two years you get 4GB data which gives you a lot more room for maneuver. £38 monthly is still quite a lot of money though so you might find it's still worth paying more for more data. Total cost over 24 months is £1021
