Hi this is a redemption cashback deal from buymobilephones.net
An 18 month contract with 600mins and 500 texts plus a booster (don't pick the internet one 3gb comes free with all android phones) works out a £15 a month.
My hubby has this phone and I think its great I'm always pinching it and is being updated to latest version of android.
If you go direct through t-mobile this deal will cost you £25 a month for 18 months plus £36 for phone = £486 so this is nearly half the price
Obviously you will have to claim the cashback but looks like they have made it pretty easy for you now.
£25 quidco or £30 topcashback on top
