I was looking for a good contract deal with a good phone and couldn't find anything for less than £30 that was from an OK company and had good minutes and data included. I had given up until yesterday, when I was checking, just in case new deals popped up and found this on http://www.mobiles.co.uk
Samsung Galaxy S5 Shimmering White (free)
for less than £25 a month!
I ordered one yesterday, received it lunch time today and was immediately on the phone with my old provider for my PAC. When they asked why I was leaving and said that they can try to match any deal that I have found, so I told them about the deal and they said that it wasn't possible to match :)
And as it comes from mobiles.co.uk, it is also unlocked :)
