There are pay monthly sim only deals, I am on one myself with Three so I am not tied in. Hence why I mentioned looking at the cost to buy the phone outright then get a pay monthly sim deal, could save you some money.
Yea, I just worked out all the costs based upon buying the phone new, buying a PS4 new and then the average price for the contract allowance as a rolling contract.
It seems the deal is slightly cheaper. Unless I bought something second hand.
At some point, I will no doubt be buying a PS4... I won't use it much, as I'm a PC gamer, but still, a console would be nice in the living room. My old 360 isn't in the best shape.
Overall, it's costing a little more getting it under a monthly payment, but it's handy I guess. Plus, I'll sell my N5 and pay off a chunk of the contract (if you can do that?)
