Risk it by taking cash back into account...
It is for those ppl don't have cash...

I would say get the phone for £299, then get Giffgaff £12 p.m

That spending extra £1 per month and not tie with contract.

This is way too expensive. You'd have to be mad to get this

Why wouldn't you just buy the phone and use Ovivo?

I moved from GiffGaff to Ovivo a year ago, I've only had to splash out £10 once and that was last month.
